24 | DRAINAGE PUMPS MADE oF STAINlESS STEEl, INoX
Drainage pumps made of stainless steel, INoXThese pumps are designed to meet the tough requirements from mines, construction sites, landfill sites and other applications that deal with corrosive water. one application is in mines where the water becomes caustic and destroys conventional pumps in matter of days. The pumps may also be used in applications where saltwater is pumped, like shipyards, fish farms, construction works in harbours and offshore projects. All INoX pumps can handle pH values from 2 - 10. They can also be equipped with zinc anodes for extra protection.

Sludge pumps made of stainless steel, INoXour sludge pumps in stainless steel are used for pumping corrosive fluids with solids in harsh environment. The solids can be up to the size of 2" (50mm). These pumps are designed to meet the tough requirements from mines, construction sites, landfill sites and other applications that deal with corrosive water. one application is in mines where the water becomes caustic and destroys conventional pumps in matter of days. The pumps may also be used in applications where saltwater is pumped, like shipyards, fish farms, construction works in harbours and offshore projects. All INoX pumps can handle pH values from 2 - 10. They can also be equipped with zinc anodes for extra protection.

Pumping slurryPumping fluids with high solids concentrations is more complicated than pumping water. To avoid sedimentation in the system you need to choose the right pump size and dimensions of hoses and pipes. The concentration of solids together with their size and shape may also affect pump performance and power requirements and therefore pump choice. Remember that settled solids might need external agitators, water jets or mixers to get them back in suspension and allow them to be pumped.
As each application requires its own calculation, we recommend you to contact your Grindex dealer for more information about slurry pumping.

50 | GRINDEX PUMP SCHool
Grindex Pump SchoolThe school consists of technical articles, intended to help pump users with common matters in pumping with submersible pumps.
A drainage pump is the most commonly used pump type at construction sites. It is used for pumping water with less abrasive solids, like clay. Sand and solids in suspension can also be pumped, up to the size of the strainer holes (normally 0.3-0.5" / 7-12 mm). As sand is quite abrasive to the pump, it must not be too concentrated.
Sludge pumps are suitable for pumping water with solids, as well as for pumping sludge. The solids can be up to the size of the pump inlet diameter (normally 1.3-3.1" / 32-80 mm).
Pumps made of stainless steel are often used in copper mines, gold mines and other applications with corrosive fluids. An Aluminum pump can handle water with pH values from 5-8, while a stainless steel pump can cope with pH values from 2-10.
Slurry pumps are designed to handle abrasive solids in suspension, like sand, gravel and concrete, in high concentration. They are also frequently used to move sand in suspension, i.e. at a dredging operation. To cope with the abrasives, the hydraulic parts of a slurry pump are often made of a very hard metal alloy. For improved performance, bigger slurry pumps can be equipped with agitator.
Part 1: Choosing the right pump type for the job
| 51GRINDEX PUMP SCHool GRINDEX PUMP SCHool
Plug and pumpAn electrical submersible pump is easy to use, just plug it in and pump. Several small pumps, placed where the need is for the moment, can pump the water to a dedicated collecting pit through long hoses. As the smaller pumps only weights 30-50 lbs (14-25 kg), you can carry the pump with you as the works moves to different spots at the site.
In the collection pit, a bigger pump is installed and pumps the water away from the site. By connecting hoses from several pumps to the pit, you can easily dewater a large area with just a few pumps.
52 | GRINDEX PUMP SCHool
Despite the simplicity, there are a few details to consider for optimizing the pumping:
Arrange the pump so it doesn’t burrow itself into sand or clay. This is a common problem at construction sites. It can be avoided quite simple by placing the pump on a bed of coarse gravel or a plank. The pump can also be hung freely by a rope or chain, or put into a cut-down and perforated oil drum.
Avoid sharp bend on the hoseAs sharp bends, kinks and pinching of the hose are reducing the capacity of the pump, a lot is won by avoiding those circumstances. Turning the pumps discharge connection so the hose doesn’t begin with at kink is easily arranged; it can be fitted vertical or horizontal on almost all Grindex pumps.
Part 2: Pump arrangement
| 53GRINDEX PUMP SCHool GRINDEX PUMP SCHool
Tandem connectionIn order to achieve higher pumping heads, two or more drainage pumps can be connected in series. For this purpose, a series connecting flange is available as an accessory. It is important that the hoses are equipped with check valves, preventing the pumps from suffering from wear when the water runs back from high heads uncontrolled if a power failure should occur.
Long distance pumping Tandem connection of pumps can also be used when the water needs to be pumped a longer distance. A simple arrangement can be pumping the water to a dedicated collection pit. The pit should be equipped with another pump, passing the water on. This technique can also be used for dewatering a greater area with several pumps spread out, pumping the water to a collection pit. The pit is then equipped with a greater pump, that pumps the water away from the site.
54 | GRINDEX PUMP SCHool
The pumped water is often containing solids that cause wear on pumps, valves and other dewatering equipment. This problem is very common in mines and tunnel construction sites. When pumping water that contains solids (like drill cuttings and sand), there is a risk of sedimentation in the system. A typical symptom is pipes and/or hoses that get filled with sediment, resulting in capacity losses. When the amount of solids increases, there is also an increase of wear on the pump.
one way to prevent this is by using sedimentation tanks where the drill cuttings may settle while the rest of the water is pumped away. The tank needs to be as close to the source as possible, ensuring that the solids are pumped as short distance as possible where the solids can settle in peace. To ensure the efficiency of the sedimentation tank, it needs to have as big surface area as possible. The more solids present in the water, the more care should be taken in the design of the sedimentation system.

For applications where solids can not be avoided, there are recom-mendations for the velocity of the medium in the discharge line: Mixture Min. velocity in discharge line
1. Water + coarse gravel 13.1ft/s (4 m/s)
2. Water + gravel 11.5 ft/s (3 m/s)
3. Water + sand
Sand particles < 0.004 in (0.1 mm) 8.2 ft/s (1.5 m/s)
Sand particles < 0.024 in (0.6 mm) 4.9 ft/s (2.5 m/s)

All pump capacities are measured for clean water, directly at the discharge outlet. When connecting a hose you need to consider the friction losses that come from the size and length of the hose. The chart below shows this.
