Welcome to Grindex Pump handbook!
With this handbook we want to share some of our wide experience in pumping with sub-mersible pumps. You will find an overview of all Grindex pumps with technical details and a pump school, intended to help pump users with common matters in pumping with sub-mersible pumps. The handbook also contains more sophisticated technical information, like pH tables and graphs that show friction losses in pipes and hoses.
We are sure you will find this handbook useful. This handbook is also available for download from our website, www.grindex.com/us. If you need more copies, please contact Grindex.

Small dewatering and sludge pumps
These small dewatering and sludge pumps are small, easy to carry, yet still intended for professional use. They are frequently used in construction and rental applications, flood relief in basements and other applications that require lightweight pumps. The sludge pump Solid has set a new standard for lightweight sludge pumps and is appreciated all over the world. It can pump solids in suspension up to thesizeof1.5”(38mm).

dewatering pumps made of stainless steel, Inox
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 a matter of days. The pumps may also be used in applications where saltwater is pumped, like ship-yards, fish farms, construction works in harbors and offshore projects. All INOXpumpscanbeequippedwithzincanodesforextraprotection.

Slurry pumps, bRaVo
Grindex slurry pumps are designed for use in quarries, mines, dredging, cleaning of settling ponds and other abrasive other industries that require pumps with very high durability. Each part of the BRAVO pump is designed for maximum endurance and reliability–anabsolutemustwhenpumpingslurry.Wear is reduced by using NiHard 4 for all hydraulic components. NiHard 4 is a nickel alloy and one of the hardest materials available today. All BRAVO pumps can handle liquids with pH values from 4 up to 10.

Grindex Pump School
A dewatering pump is the most commonly used pump type in mines and at construction sites. It is used for pumping water with less abrasive solids, like clay. Sand and solids in suspen-sioncanalsobepumped,uptothesizeofthestrainerholes(normally0.3-0.5”/7-12mm).Assandisquiteabrasivetothe pump, it must not be too concentrated.
Sludge pumps are suitable for pumping water with solids, as wellasforpumpingsludge.Thesolidscanbeuptothesizeofthepumpinletdiameter(normally1.3-3.1”/32-80mm).
Pumpsmadeofstainlesssteelareoftenusedincoppermines,gold mines and other applications with corrosive fluids. An alu-minum 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 sus-pension, 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 NiHard 4, a very hard metal alloy. For improved performance, slurry pumps are generally equipped with an agitator.
Grindex Pump school
The school consists of technical articles, intended to help pump users with common issues in pumping with submersible pumps.
Part 1: Choosing the right pump type for the job
Plug and pump
An 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 weights22-40lbs(10-25kg),theyareeasily moved to different spots through-out the site.
In the collection pit, a bigger pump is installed and pumps the water away from the site. By this method you can easily dewater a large area with just a few pumps.

Grindex Pump School

Grindex Pump School
To install an electric submersible pump is easy; place it in the water, connect the hose and turn on the power. Despite the simplicity, there areafewdetailstoconsiderforoptimizingthepump:
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 simply 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 hose.As sharp bends, kinks and pinching of the hose are reducing the capa-city of the pump, a lot is won by avoiding those circumstances. Turning the pumps discharge connection so the hose doesn’t begin with a kink iseasilyarranged;itcanbefittedverticalorhorizontalonalmostallGrindex pumps.
Part 2: Pump arrangement
Tandem connectionIn order to achieve higher pumping heads, two or more dewatering 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 equip-ped with check valves, to prevent damage from water running back through the pump 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 from the site.
54
Grindex Pump School
55
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(likedrillcuttingsandsand),thereisariskofsedimentationin 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. To ensure the efficiency of the sedimentation tank, it needs to have as big of a surface area as possible. The more solids present in the water, the more careful the design of the sedimentation system is necessary.
Part 3: Sedimentation
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+coarsegravel 13.1ft/s(4m/s)
2. Water+gravel 11.5ft/s(3m/s)
