Material designations and their meaning Wear and tearPumps or parts of pumps are subject to wear in accordance with state-of-the-art technology (DIN 31051/DIN-EN 13306). This wear may vary depending on operating parameters (temperature, pressure, speed, water condition) and installation/usage situation and may re-sult in the malfunction or failure at different times of the above-mentioned products/components including their electrical/electroni-cal ciruitry.Wear parts are all components subject to rotary or dynamic strain in-cluding electronic components under tension, in particular:

- Seals (incl. mechanical seal), seal ring- Stuffing box - Bearing and shaft- Impellers and pump part- Ball race and wear ring-Wear ring / wear plate-Macerator - Capacitor- Relay / contactor / switch- Electronic circuits, semiconductor components etc.

Pumps and continuous-flow machines (like submersible mixers and recirculation pumps), as well as their components with coatings (cat-aphoresis coating, 2K- or Ceram-coating) are subject to constant wear due to the abrasive fluid contents. It is for that reason that the coating is also listed with the wearing parts contained in these units!

We do not accept liability for faults or defects arising from natural tear and wear.

Fields of application, principle of operation and standards

Planning guide Borehole pumps Fields of application, principle of operation and standards Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"Fields of applicationWilo submersible pumps are designed for the economic, environmen-tally safe and hygienic pumping of potable water, mineral water, thermal water and industrial water. They are therefore also increas-ingly being installed, in addition to their traditional field of applica-tion i.e. installation in deep wells in pits, collection, storage and intermediate tanks, as well as in lakes, dams and rivers.

The product portfolio is divided into three segments: Building services / domestic water supply: Application in domestic

water supply and for irrigation from deep wells and rainwater storage tanks; rainwater utilisation and industrial water supply in the domes-tic sector; as well as fountains and potable water supply

Municipal and industrial water supply: Water pumping and pressure boosting from deep wells and rainwater storage tanks; water control in domestic and professional applications; decentralised water sup-ply; sprinkling and irrigation from deep wells, lakes and rivers; ground water preservation and lowering in street construction and open-pit mining; industrial pumping of cooling and industrial water; sea water applications, desalination systems and thermal water, sprinkler and fire extinguishing installations

Polder pumps: Sea water applications, particularly in offshore envi-ronments

Design and principle of operationSubmersible pumps are centrifugal pumps which form a compact unit together with the motor. They pump clean or slightly muddy water, require no maintenance and are distinguished by their high efficiency and long service life. The hydraulic component, single-stage or mul-ti-stage in single-stream sectional design, has radial or semi-axial impellers, depending on the required flow rate. The housing has re-placeable stationary wear rings in the sealing gap area of the impel-lers. Shielded, fluid-lubricated friction bearings are used as bearings for the blades. Pressure connection optionally with non-return valve or pressure port with threaded or flange connection.

Single-phase or three-phase squirrel-cage motors with waterproof insulated windings are used as submersible motors. The motor filling is potable water or a Wilo-specific factory filling (antifreeze-protect-ed). This is used for cooling the winding and for lubricating the fric-tion bearings. Volume compensation while heating and cooling is achieved by means of a relief diaphragm in the lower part of the mo-tor. The hydraulic axial thrust of the pump and the rotor weight are absorbed by the axial friction bearings. The motor is sealed against the fluid with a mechanical seal (SiC bearing surfaces) and/or with ro-tary shaft seals at the shaft outlet. The power cable connection with the motor is direct and pressure-tight.

StandardsWilo submersible pumps are subject to the following standards:

DIN EN ISO 9001The Wilo quality system ensures that the quality standards are com-plied with in all operational areas in accordance with DIN EN ISO 9001:2000

CE conformityFulfilment of the technical safety requirements of the EU Machinery Directive for pumps and pump units; visible documentation of this matter is provided by the CE mark shown on every pump

KTW approvalKTW approval has been granted for the unproblematic use of plastic components, power cables and coatings in potable water

ISO 9906International standard for the inspection of pumps

DIN EN 60034 (VDE)European standard for all electric motors

VdS certificateThe certificate documents the high quality and reliability of products specially made for fire protection

Water extraction and supply


Planning guide Borehole pumps Water extraction and supply Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"Water extractionWater is one of the most important elements in existence. Water is necessary for life to emerge and for life to be maintained. Neverthe-less, water is not to be found everywhere and it can usually not be used in its natural form. Water extraction therefore comes first and is something that can be accomplished in a wide variety of ways.

Rain waterRain water is to be found almost everywhere, depending on local rainwater heights. Water supply on this basis is however very uncer-tain, due to its irregular and unpredictable distribution. Another fac-tor to consider is that, because of its composition, rainwater is not immediately suitable as a source of potable water.

Surface waterRiver waterRiver water is exposed to the highest degree of contamination and is therefore the least suitable source for potable water supply. It is only when no other water is available that river water should be resorted to.

Because of its extreme quality fluctuations, river water is mainly used as a source of industrial water supply. The level of contamination is frequently so high that its economical use as water supply is either not possible at all or only to a limited extent. In order to extract water with low levels of particles in suspension, to achieve a better temper-ature progression and to simplify the water treatment process, at-tempts are made - to the extent permitted by the respective geolog-ical formations - to utilise river-bank filtrate. In addition, river water is increasingly being applied for artificial groundwater replenishment.

Lake waterLow-nutrient, deep lakes with sufficient inflow are the ones chiefly suitable for lake water extraction. Unlike flat lakes, lakes with depths exceeding around 40 m have a similar temperature equilibrium to that of ground water. The quality of the water depends essentially on the intake of contamination from the feeders of the catchment area and from the shore areas, as well as on the utilisation of the lake (e.g. leisure and recreation). Generally speaking, only the mean annual in-flow is extractable, minus losses, while the volume of the lake has a compensatory effect.

Reservoir waterReservoir dam basins are created by the artificial damming of river valleys. They are able to accumulate large potable water and industri-al water reserves while at the same time acting as storage basins for regulating the drainage fluctuations of rivers and as water storage systems for hydroelectric installations (multipurpose reservoir dams). The water level in the storage basin of a reservoir dam generally fluc-tuates considerably, depending on the extraction of the water for the intended use. The varying water level in the reservoir basins is the es-sential difference between these artificial lakes and natural lakes, which generally speaking have less water level fluctuations. The wa-ter quality is, as is the case with natural lakes, determined by the quality of the inflow from the catchment area.

Sea waterThe majority of all rainfall originates from evaporation that takes place in the atmosphere above the world's oceans, thus making them decisive for water management. The earliest attempts to desalinate sea water date back to antiquity. Nonetheless, the question of the extraction of potable water and industrial water has become increas-ingly urgent over the past 40 years, particularly in the arid and semi-arid parts of the world. Fully developed constructions are already available for desalination installations, but the emphasis here is on developing systems that offer even higher performance levels.

Ground waterGround water from sand layers is the most suitable type for potable water and domestic purposes. It is to be found in the vicinity of river courses, in glacial valleys and sandy deposits left over from the ice ages.

Porous soils (sands, gravels, etc.) have a filtering and thus a purifying effect that is entirely or partially absent in fissured stone formations (contiguous crevassed spaces). When the ground water has spent enough time in porous ground and has flowed a sufficiently long dis-tance, it will take on the mean ground temperature (8 - 12 C) and become germ-free. These properties (consistent temperature, good taste, absence of germs, etc.) make the ground water a particularly suitable source of potable water supply.

Organic and inorganic substances are absorbed and dissolved by the ground layers through which the water passes. The salts that are in solution are not eliminated by the filtration effect of the ground. If harmful or troublesome limits are exceeded, then the ground water requires treatment. The dissolving power for gases increases the deeper the water is and the higher the pressure thus is.

Water purificationOnce the water has been extracted, it must then be treated for the respective requirements. The water passes through a water treat-ment plant for this purpose. Water purification is for the purpose of accommodating the untreated water to the requirements of potable water and process water usage.

Water purification essentially consists of two groups of treatment: Removal of substances from the water (e.g. purification, sterilisation, removal of iron, softening, desalination)

Addition of substances and adjustment of the parameters of the wa-ter (e.g. dosage, adjustment of pH value, ions in solution and conduc-tivity)

Which processes are used depends on the utilisation and the degree of contamination of the water:

Technical water (cooling and process water for power plants, chemi-cal processes, pharmaceuticals) frequently require a very extensive modification of the water properties, e.g. by means of desalination, demineralised water, reverse osmosis, special dosages, degasifica-tion.

Legal specifications (Drinking Water Directive 98/93/EC) and the re-quirements of the distribution system are decisive for adjusting the potable water properties. Potable water can be preset by mixing wa-ter from a variety of sources in order to achieve a more homogeneous quality (e.g. a mixture of river-bank filtrate and reservoir dam water).

Bathing water in open air and indoor swimming pools is treated in ac-cordance with DIN 19643. Flocculation, filtration and chlorine disin-fection are the standard procedures.

Water treatment is frequently necessary when waters with different compositions are mixed. The pH value in mixed water is frequently shifted thereby to such an extent that the calcite solution capacity (i.e. the capacity of the water to dissolve calcium carbonate) exceeds permissible levels (according to the TrinkwV (German drinking water ordinance), the limit value for the calcite solution capacity is 5 mg/l). This ability to dissolve calcium carbonate is frequently referred to as the aggressiveness, or more precisely, the "calcium aggressiveness" of the water.




The treatment of ground water from a sufficiently shielded aquifer is as a rule less complex than that of spring or surface water. The re-moval of iron and of manganese are probably the most frequently used methods for the treatment of ground water. The question of to what extent the chlorination of the ground water is required usually depends on the condition of the pipe system. However, more sophis-ticated processes are used for the treatment of surface water. These frequently include ozoning, flocculation with subsequent sedimenta-tion or filtration and activated carbon filtration for the elimination of absorbable pollutants. These processes are followed by an obligatory disinfection.

Mechanical, chemical and biological processes are applied for water purification.

Water purification processes

Process System components Purpose

Screening Rake, sieve drum, micro-strainer Removal of large solids and floating matter

Sedimentation Grit chamber, settling tank Removal of smaller floating matter, sand, floccula-ted suspended solids

Filtration Filters, sand filters Removal of suspended solids (particles)

Flotation Flotation basin Removal of fine dirt particles by blowing in air

Flocculation Flocculation basin Removal of colloid substances and fine dirt parti-cles by adding flocculants (discharging the parti-cles) and adjusting the pH value. Can also com-bined with a filtration (flocculation filtration).

Precipitation Precipitation basin and/or precipitation filtrati-on

Precipitation of impurities, e.g. iron or manganese oxides by ventilation and subsequent sedimentati-on or filtration.

Adsorption Active carbon filter Agglomeration of, for example, adsorbable haloge-nated hydrocarbon compounds (AOX) or dyes

Deacidification Deacidification unit Removal of aggressive carbonic acids. Used to pre-vent corrosion in the pipework.

Softening Water softener unit Removal of Ca2+ and Mg2+

Desalination Desalination unit Removal of salts, e.g. for converting sea water into potable water and for irrigation

Stripping Stripping basin Removal by blowing in air/gases. Depending on the vapour pressure, this causes water constituents in solution to be transferred to the gas phase and thus to be removed from the water.

Cooling Cooling towers, cooling ponds, heat ex-changers, etc.

Reduction of the temperature in order to fulfil the requirements of subsequent processes or usage.

Biochemical processes Example: Denitrification Exploitation of biochemical processes. With denit-rification, the nitrate content of contaminated, untreated water is reduced by adding carbon either underground or in a reactor.

Disinfection Special basin, additives introduced into the pipework

Sterilisation due to the introduction of chlorine or ozone or by UV radiation

Special treatment Special basin for contaminated sewage Special treatment of sewage that is contaminated with initially unknown substances or organisms. Examples: Untreated sewage from galvanisation plants or threadworms.

Water storage tanksThe water must be placed in intermediate storage after it has been treated for the respective application. Storage facilities for potable water or process water are referred to as water storage tanks or water reservoirs.

Types of reservoirsA distinction is made between natural and artificial reservoirs. Natural reservoirs are, for example, oceans and seas, lakes and rivers above ground or ground water. Artificial reservoirs are, for example, under-ground tanks or reservoirs formed by dams.

Underground tanksThe water level of the storage tank is lower than that corresponding to the supply pressure. The water must therefore be pumped up out of the tank for supply purposes. Underground tanks are therefore suction tanks for pumping station units and are used for compensa-tion between spring water inflow or preliminary well pumping and raising the water into the supply system. With pressure vessel pump-ing stations, they also assume some of the tasks of elevated tanks, such as the compensation of consumption fluctuations or the stor-age of fire-fighting water.

Fire water tankVery frequent, and in the case of small rural communities almost al-ways necessary, is the storage of fire water in special fire water tanks, e.g. when no central water supply is available or when the water sup-ply in the elevated tank is not sufficient for fighting major fires. Sur-face water can also be used for filling purposes, since the water is not subject to any special hygienic or technical requirements. Generally, nearby ponds are equipped with the equipment required for extract-ing fire water or artificial fire protection ponds (fire ponds) are creat-ed. Underground fire water tanks are on the other hand more practi-cal in closed areas covered with buildings.

Elevated tankThe most common form of water storage and the one to be used in most central water supply systems is in elevated tanks. These are wa-ter storage tanks in which the water level is higher than the supply area from which the water falls along a natural gradient to flow into the supply system. They are used for compensating consumption fluctuations, for maintaining a consistent pressure in the supply sys-tem, for emergency supplies and for the storage of a water reserve for fire-fighting purposes, with long-distance lines and with group water supply systems such as interim tanks and zone tanks.

If the elevated tank is set up at an appropriate height, then it also provides the required supply pressure. It is possible to have elevated tanks arranged at different static heads in order to provide different pressure stages (hilly countryside). Tanks are, however, used not only for water storage but also for pressure reduction; it is primarily in supply networks with large static head differentials that so-called discharge flow-through tanks are used, since otherwise the pressure at the lowest point of the water supply system would be too great.

Ground-level tankThe water storage tank is set up at a favourable location in terms of altitude and position, with most of the structure installed under-ground and covered with earth. This form of elevated tank is fre-quently preferred, because it is the most economic and reliable type available.

Water towerWater towers can store only small amounts of water, but neverthe-less provide sufficient pressure for the pipe systems below them due to their static head.

If no favourably positioned ground site is available, then water stor-age is carried out in the vicinity of the supply area in water chambers which are located, in the upper part of a tower-like building struc-ture. The water tower is occasionally designed as a standpipe tower, where the bottom of the water chamber is the foundation bed. The costs of a water tower are considerably higher than those of a ground-level container (around 5 to 10 times as high). The water lev-el of the storage tank is therefore generally not positioned as high above the supply area as is the case with a ground-level tank, and its volumetric capacity is kept smaller.



Well-sinking

Planning guide Borehole pumps Well-sinking Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"Well-sinking is used for the installation of structures for pumping ground water. A cover and a lateral sealing of the sump or of the borehole to the surface are used to protect the wells against the infil-tration of contamination. The water can be pumped using various pump models, such as submersible pumps. Water extraction is based on the yield of the ground water source and the performance of the filtration system, which must prevent any flushing out of the ground into the well.

TypesShaft wellManual or mechanical excavation is used to open up a vertical sump down to the body of the ground water. The pit is secured with ma-sonry or finished parts prefabricated with (reinforced) concrete as it is deepened. The flow of the ground water to the well takes place through the bottom of the sump and/or of a vertical filtration system. This procedure is only suitable for lesser depths (generally considera-bly less than 40 m).

Usually the construction of a shaft well is as follows for a simple de-sign with minor depths and individual objects (this work is dangerous and should be performed by a specialist company):

Concrete sump rings (diameter e.g. 1 000 mm) are used. A small amount of earth is dug out, upon which the first well casing

(without step irons) is placed in exact horizontal position. This first ring casing can be given a steel blade on its underside.

The earth under the first well casing is excavated, the well casing sinks accordingly and additional well casings can be placed on top of it.

Abyssinian wellA pipe with a cone end and a filtration system arranged underneath (open part of the pipe) is driven down as far as the ground water level by ramming it. This method is particularly favoured by hobby handy-men for small installations and lesser depths. These wells called Ab-yssinian wells are also referred to by specialists in Germany as "Bau-haus wells". Advantage: Easy to set up. Disadvantage: Last only approximately 5 years.

Bore well / vertical wellDrilling is carried out down to the ground water body. A filtration sys-tem is provided in the water-carrying layer. This method can be used for great depths (more than 1000 m).

Horizontal filter wellStarting in a sump, horizontal drillings with filtration systems are pushed forward into the ground water body. These wells enable large extraction quantities.

Use in sprinkler systems


Planning guide Borehole pumps Use in sprinkler systems Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"Sprinkler systems are automatic fire extinguishing systems which are used for fire prevention in special building structures such as sky-scrapers, commercial buildings, department stores, industrial instal-lations, places of public assembly and underground car parks.

The sprinkler head was invented in 1874 by the American Henry S. Parmalee, a piano manufacturer. The water spraying nozzles were originally sealed with a small metal plate which was held in place by a device connected to a solder. The solder melts with a corresponding rise in temperature and the retaining device releases the small metal plate, which is in turn expelled by the pressure of the water behind it, which then starts spraying.

Several sprinkler heads that are connected to a water pipe system are fitted on the ceiling of the room or on the upper part of the side walls. The sprinkler heads are in turn sealed with glass ampoules that are filled with a special dyed fluid. A constant water pressure prevails in-side a sprinkler system that is monitored at the central sprinkler con-trol point. In the event of a fire, the special fluid in the glass ampoules heats up and expands, causing the ampoules to burst. This opens the nozzles and water is released from the sprinkler pipe network. The colour of the special fluid indicates the triggering temperature. This triggering temperature is on average approximately 30 C above the anticipated room temperature.

The resulting drop in pressure is detected, which leads to the opening of special valves and the starting of our sprinkler pumps. Water is im-mediately pumped at high pressure out of the tanks provided for this or from a water connection designed for that purpose and into the sprinkler system. The water is expelled from all open water nozzles and extinguishes or minimises the fire.

The dimensions of the pipework and of the water supply are designed in such a way that only enough water for a specific number of water nozzles is available, which is called the effective surface. If more sprinkler heads open than are available on the effective surface, then the amount of water available per sprinkler head drops and the effec-tiveness of the systems is reduced.

Sprinkler systems are therefore primarily for fighting a fire in its initial stages (incipient fire) and not for fighting a blazing fire. A fireproof partition must be erected between areas that lack a sprinkler system and ones that have one in order to ensure that a blazing fire originat-ing in an unprotected area is not able to cross over into an area of the building that is protected with a sprinkler system.

What are called dry pipe systems are used in areas where there is a risk of frost causing the sprinkler lines to freeze up. The pipe system in these installations is filled with compressed air. The installation is not filled with water until a sprinkler head is triggered.

As is the case with conventional fire detectors, sprinkler control points are generally connected to fire detection systems and trigger a fire alarm when a drop in pressure has been detected. Depending on the programming, this is transmitted to the police, fire department, factory security office or other offices providing aid.

As a rule, the configuration of sprinkler systems in Germany is in ac-cordance with the VdS Regulation CEA 4001 (VdS Damage Preven-tion, CEA Comit Europen des Assurances). The American Standard of the NFPA (National Fire Protection Association) - also known in modified or further developed form of the directives as FM (Factory Mutual) Standard - is however increasingly enjoying the favour of in-ternational building companies and is as a rule also accepted in the meantime by German government authorisation agencies. The sys-tem is configured according to the fire hazard level in the area to be protected by determining the water saturation of the fire source be-tween 2.25 mm/min and 30 mm/min (1 mm/min is equivalent to 1 l/m2/min), the effective time between 30 and 90 min and of the dis-tance between the sprinkler heads.



Offshore applications

Planning guide Borehole pumps Offshore applications Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"DefinitionThe term "offshore installations" refers to structures permanently lo-cated either on the open sea or in coastal areas. An example of this is an oil rig.

Platforms are referred to as oil rigs if they are used to bore holes in the sea bed for the purpose of tapping crude oil and natural gas fields.

TypesThere are different types of oil rigs. Our pumps are used chiefly on the following two types:

Jack-up rig: This platform stands on the rig's legs which in turn stand on foundations on the sea bed. The platform can be moved vertically i.e. along the legs. The internal structure of the platform is thereby used partially as a ballast tank which is filled with sea water. Trans-port is performed by special ships. Jack-up rigs are usually to be found in flat water.

Semi-submersible rig: The platform floats on pontoons, which ensure the buoyancy of the structure while being used at the same time as ballast tanks. It is possible to keep the oil rig itself stable, even under adverse weather conditions, by filling or emptying the ballast tanks. Positioning above the borehole is ensured by the use of an anchor or by its own drives. This type of oil rig is very mobile and can be used in water depths down to approximately 1800 m.

MaterialsSea water is an extremely corrosive fluid. To be able to use pumps in it, materials which are resistant to sea water must be used . All parts that come into contact with the fluid in our units that are made for use in sea water are either made of bronze or stainless steel or are coated with Ceram. The use of these high-quality materials makes it possible to achieve a long service life of the pumps.

ApplicationSubmersible pumps or polder pumps and submersible sewage pumps are used on oil rigs.

On jack-up rigs, the submersible pumps are installed either on the rig's legs or on the derrick itself. They pump sea water on to the deck where it is then distributed to various consumers, e.g. the fire-fight-ing system.

The submersible pumps are also installed on the derrick on semi-submersible rigs and pump like with jack-up rigs sea water on to the deck. In addition, polder pumps are installed in the ballast tanks in order to fill or empty them.

Submersible sewage pumps are used for the rapid filling of the ballast tanks on jack-up rigs before the platform is raised to its working height.

Oil rig equipmentThe complete equipment and planning of our units on oil rigs is car-ried out by our partner, the S&N Pump Company in Houston, Texas (www.snpump.com).

Material selection by water analysis

Planning guide Borehole pumps Material selection by water analysis Subject to change 09/2008 WILO SE Wilo Catalogue B2 - 50 Hz - Borehole pumps 3" to 24"CorrosionA preliminary assessment of the corrosion potential for pump unit components can be done based on a water analysis. The passivity of any material in terms of the pumped fluid requires that a suitable protective layer is formed on the surface that is in contact with the fluid. In the case of grey cast iron, this is what is called the "lime-rust protective layer" which, depending on the composition of the pumped water, can form and help prevent further corrosion. Two cri-teria are necessary for the successful effect of this protective layer:

Fig. 1: Tendency to deposit limy layers

Fig. 2: Chemical resistance of the deposited protective layer to the existing carbonic acid

Tendency to deposit limy layers according to Fig. 1Main parameters: pH value and carbonate hardness and/or acid ca-pacity KS 4,3 of the pumped water.

Chemical resistance of the deposited protective layer to carbon acidic according to Fig. 2. Main parameters: Free CO2 content and carbonate hardness / acid ca-pacity KS 4,3 (the aggressive range is equivalent to the free, non-cor-responding CO2 content).

The line shown in the figure represents the equilibrium curve (GK) between supporting and damaging any layer formation or its incapa-bility. In the "aggressive" range (on a grey background), materials are probably vulnerable to corrosion in the absence of protective layers. In such cases we recommend our special version C or D made of more corrosion-resistant materials.

Only the carbonate hardness (sum of calcium and magnesium bicar-bonate Ca(HCO3)2 + Mg(HCO3)2) is decisive for the formation of the protective layer, not the overall hardness.

Additional constituents and/or parameters of natural waters can have a damaging effect on the resistance of standard materials above the specified concentrations:

SO42 approx. 200 mg/l

Cl- approx. 150 mg/l Evaporation residues approx. 500 mg/l Electrical conductivity approx. 1000 S/cm And traces of Cl2, H2S, NH3, NH4, sulphur, humic acids, hydrocarbons.

The presence of combinations of these constituents, even in smaller concentrations, can cause materials to be corroded. The warmer an aggressive fluid is, the faster it corrodes a material. If critical sub-stances are present, please consult us at the company. Wilo offers technically mature special versions even for aggressive fluids, such as sea water or brackish water.

Formation of troublesome coatings and depositsCoatings impair the pumping capacity and/or heat dissipation of the drive motor. Undesired deposits may be formed if there is an exces-sive tendency toward lime deposits according to Fig. 1 (hard water) (e.g. iron approx. 0.2 mg/l or manganese approx. 0.1 mg/l, ochre coatings or manganese dioxide).

Solid matter in the pumped fluidIf the pumped fluid contains solid matter, material may be deposited in the pump - depending on its content and composition. Wilo sub-mersible pumps are designed for a maximum sand content of 35 mg/l. Pumps with components made of more wear-resistant materials on request.

Gaseous constituentsSome applications require the pumping of gaseous fluids (e.g. mineral and thermal water). Gas bubbles can considerably change the pump-ing characteristics under certain circumstances and can lead to unfa-vourable operating conditions. Please consult us at the factory in such cases.
