a cost-effective alternative compared to special materials

Later coating/repairs possible

Impeller and suction port coating A perfect combination, e. g. C2 + C1

Can also be used in seawater and brackish water, as well as in industrialsewage areas

Wilo Ceram offers all-round pro-tection for all unit components, whether they are inside or on the surface. Depending on the field of application, different Wilo Ceram coatings are offered, which are applied using various methods. For use in special fluids, the indi-vidual Ceram versions can also be combined with each other.

Ceram C0 is used both for the outer coating as well as for the interior coating. This is applied using the airless method in one layer with a thickness of 0.4 mm.

Impeller with Ceram coating is onlyreplaced after 2000 hours

An impeller made of cast iron mustbe replaced after 500 hours

Sewage and sewage treatment plant pumps are constantly beingexposed to aggressive fluids. Corrosion and abrasion, as well as UVlight, heat, cold, salt, condensate and the alkalinity influence the surfaces and material structures of the units, sometimes with consi-derable impairment to the performance. This significantly reduces thehydraulic efficiency of a pump (see graph). This not only results in a higher energy consumption, but also leads to a greatly reduced service life due to the displacement of the load locus for the motorand hydraulics.

A specific application case uses just the example of an impeller coatedwith Ceram to illustrate the performance and the associated poten-tial for savings. In a kaolin plant, the fluid is so abrasive due to thelarge amount of very small-grain sand that a cast-iron impeller, whichnormally has an operating time of about 100,000 h with no problems,already had to be replaced after 500 hours of operation.

In a test period of 15 months, a total of four cast iron impellers weretherefore replaced. This resulted in the following: Acquisition costs Loss in efficiency due to the corroded material This resulted in increasing energy costs Downtimes due to removal and installation

Under the same conditions in exactly the same time period, an impel-ler coated with Ceram was used. This impeller only had to be replacedafter about 2000 hours of operation. The coating could withstand thehigh mechanical load for four times as long.

If one takes the overall costs over the entire service life of the pumpinto account, the investment costs for a unit coated with Ceram areless than 1 1 % and thus negligible. In addition, there is a high savingspotential due to fewer repairs being required, resulting in fewer system downtimes. Therefore, a Ceram coating already pays for itself withinthe first 500 hours of operation, i.e. within the first year.

Whether in the municipal waterand sewage management, in theoffshore area or industry: Every-where where pumps and systemsare exposed to aggressive fluids,Wilo Ceram offers long-lastingprotection. Companies all overthe world trust the one-of-a-kind

coating from Wilo. For a goodreason: Wilo Ceram increases theservice life of all mechanical com-ponents, lowers the energy costsnoticeably, thanks to the higherefficiencies, and is therefore veryconvincing with their minimumlife cycle cost.

Surface preparationIn order to achieve the best results with this product, proper preparation of the surface is of criticalimportance. The exact requirements change depending on the application, expected period of ser-vice and original surface condition.

SteelMake sure it is clean, dry and free of grease. The best results are attained by removing rust by blast-ing in accordance with DIN EN ISO 12944-4, standard cleanliness grade Sa 2.5 - 3. The roughnessshould be at least 50m deep. A test certificate for the blasting equipment must be available.

Please ask for our advice on preparing other surfaces.

Material preparationThe material is supplied in the agreed mixing ratio. Mix all the hardener component into the basiccomponent, preferably using a mechanical mixer, also mixing around the walls and bottom of thecontainer. Only mix as much material as can be applied during the pot life.

The mixing ratio is 4:1 by weight.

Application instructions

Object requirementsThe surface and air temperatures must be at least +10C, and the relative air humidity at most80%. The temperature of the surface to be coated must be at least 3C above the dew point. Lowtemperatures slow down hardening and make application more difficult. For the coating to hardencompletely, the surface temperature must be above the minimum hardening temperature. High airhumidity or temperatures below the dew point can cause condensation to form on the substrate orthe coating surface. This can cause problems of adhesion to the surface and between layers. Theseobject conditions must be maintained during the application and hardening period. If the tempera-ture or humidity approach the threshold values, we recommend the use of heating or drying equip-ment. Ceram C0 can be applied on small surfaces by roller or brush.

Pot life

This table shows the practical hardening time from the start of mixing.

Coating layers and mate-rial requirements

Ceram C0 is applied in layers of 400m to around 1000m, depending on the media and intendedduration of protection.

Theoretical yield: 1.8m2/kg at 400m or 0.9m2/kg at 800m.

Theoretical consumption: 0.60kg/m2 at 400m or 1.15kg/m2 at 800m.

In practice, consumption depends on the surface properties and the application method.

Use the following formula to determine how much is needed to cover a given surface:

Density x area (m2) x average thickness (mm) = consumption (kg)

Repeat coating intervals / subsequent coating

Another layer of Ceram C0 can applied after around 16hours up to 24hours at +20C. The surfacesmust be clean, dry and free of oil or grease. If this interval is exceeded, the coating must be blasted.In hot sunshine, the repeat coating interval is much shorter. Take suitable measures to prevent this.

Material needed - Cleaning agent for cleaning the surface- Abrasive paper for roughening the surface (select the roughness according to the surface)

- Paintbrush for applying the coating (select the size according to the extent of the damage)

- 2 component coating (Ceram C0 + hardener)

- Vessel for mixing the two components

Working steps 1 Lift the WILO machine from the basin, place it on a secure surface and clean it.2 Thoroughly clean the damaged area with suitable cleaning agent.

3 Roughen the surface around the damaged area.

4 Mix the 2 component coating (Ceram C0 + hardener) in a 4 to 1 ratio in a suitable vessel.

5 Wait 10 to 15minutes.

6 Apply the finished Ceram C0 coating to the damaged area with a suitable paintbrush. Makesure the coating is of at least the minimum thickness: 400m

If you are using a combination of different Ceram types (e.g. C2+C1),please consult the manufacturer.

7 After repairing the damage, let the Ceram C0 completely dry. See Hardening time.

Cleaning tools Use a commercial solvent (acetone, alcohol or methyl ethyl ketone) to clean your tools immediatelyafter use. Once the material has dried, it can only be removed by abrasion.

Storage Store at temperatures between 10C and 32C, slight deviations during transport are acceptable.The containers can be stored unopened for 12 months.

Safety precautions Before using any products, read the material DIN safety data sheet (MSDS) or the safety regulationsregarding them. Observe all applicable safety regulations when working in enclosed rooms.

> The pumping station was equipped with 3Wilo submersible pumps with Ceramcoating.

> The submersible pumps are in dry sumpinstallation. The submersible motors arecooled by an internal circulation cooling.

> Via a special heat exchanger the heat loss ofthe motor is directly dissipated to thepumped liquid in the pump casing. Thisintensive cooling system has the effect thatthe motor while continuously operating atrated output also works safely whenemerged.

Ceram coating

Higher hydraulic efficiency and increasedresistance to abrasion.

The impeller with Ceram coating will be replaced after 2,000 hrs only and that with relatively stable efficiency course.

The cast iron impeller must be already replaced after 500 hrs.

Ceram coating

> Solvent-free less impact on the environment

> Free of pores as produced without air pockets

> Very high wear resistance due to good inside adhesion and high filling

> High adhesive strength strong resistance tohydrodynamic attack

> High wet adhesion good mechanical featureseven with chemical load
