The submersible pump is ideal for lower flow rates from 80 GPM to 1,600 GPM and high head up to 500 meters, or 1,500 feet. However, in some cases where this is the only viable type of pump a vertical pump can be adapted with a motor bracket to handle flows up to 5,780 GPM with a two or four pole motor (1,760 or 3,460 RPM). This pump can be installed vertically, at an angle, or horizontally inside a line. The energy to the motor is supplied through a specially designed electric cable designed to operate underwater.
Submersible pumps should generally have a good Soft Starter to monitor the electrical flow to the pump motor, to protect the motor in case the amperage or other electrical parameters deviate from pre-established optimal range.
The submersible pump requires a lower initial investment than a vertical pump. It cannot take as much abuse as a shaft pump, although in a clean, freshwater setting and under the right temperature conditions it can be very popular and offer sufficient durability. It is also a great option for deviated (non-vertical) wells.
The submersible pump is particularly well-suited for wells and as booster pump for industrial, commercial and municipal water uses. It is designed to function totally under water. In wells, the pump end, motor and cable are suspended within the column. When used as a booster pump it can be installed in a steel barrel, either horizontally or vertically.
Most Popular Uses
Extremely deep deviated (non-vertical) wells that would otherwise present problems for the inner column.
• Extremely deep deviated (non-vertical) wells that would otherwise present problems for the inner column.
• In areas prone to flooding where a surface electrical vertical motor could be at risk of water damage.
• Applications that need to be silent.
• Applications with restricted space.
• Applications where the pump is located horizontally inside a line or where conditions require a minimum of excavation or use of surface space.
• Dewatering applications.
• Deep water wells.
• Booster pump.
• Up to 365 LPS or 5,780 GPM.
• Up to 750 PSI or 1,730 FT.
• Newtonian fluids
Types of liquids:
• Clean, fresh water.

Discharge Elbow and Base Plate
The base plate supports the weight of the pump and anchors the pump and column to the ground. It also contains a box to house the connections for the submersible cable. The discharge elbow directs the liquid and can connect to a line.
The column connects the pump end and submersible motor to the base and its length can be adjusted based on requirements. It also directs the liquid out to a line or open discharge.
Electric Submersible Cable
Brings the power from the ground to the submersible motor.
The Pump End consists of one or more stages based on the requirements of the pump system. WARSON has from 5”-14” pumps covering a wide range of applications. The standard construction materials used are cast iron Cl-30 bowls, Bronze-844 impellers and stainless steel SS416 shafting. For longer pump life a strainer is highly recommended.
Depending on the needs it can be one or multiple stages.
WARSON offers pump ends ranging from 5”-14”. The standard construction materials used are cast iron Cl-30 bowls, Bronze-844 impellers and stainless steel SS416 shafting. For longer pump life a strainer is highly recommended.
Submersible Electric Motors
In a submersible pump, the electric motor is attached directly to the bowl using a bracket, to create a single integrated unit. The motor usually has an anti-thrust bearing to handle the pumps axial thrust while operating.
Canned pumps are used as booster pumps. The can is designed according to the flow and head of the pump and per the required pump size. Canned pumps are useful when you do not have a pit or if you need to connect the pump to a water line.
