SEI 4” CBM submersibles feature corrosion-resistant stainless steel construction and an enhanced wear resistant design for harsh & abrasive CBM environments.
Motor Special Features
- Complete stainless steel construction.
- Abrasion resistant sic/sic mechanical shaft seal to prevent sand entry into the motor.
- Oil filled motor design ensures very good conduction of heat from windings to the outer jacket of the motor. It also provide good lubrication to the ball bearings.
- Over rated motor design results into very low temperature rise for the Motor. The motor will not require a cooling sleeve up to 122°F.
- Motors have standard NEMA mounting dimensions.
- Extra heavy duty ball bearings provided to take high thrust loads as mentioned in the motor specification.
- Motor are equipped with a heavy duty Cast Iron base to prevent damage to the motor while lowering it into the well.
- Extra heavy outer body is provided for high durability.

Pump Special Features
- These pumps are provided with upthrust washer on each stage to enhance durability.
- Intermediate bearing adapters are provided at suction end, discharge end and also in the middle of the pump to provide rigid support which increases wear resistance and life of the pump.
- The bowl casings on the pump have additional metal thickness to withstand high working pressure.
- There pumps are provided with extra heavy clamp strip to facilitate better assembly of the pump which also helps in withstanding high pressure developed by the pump. It also prevents leakage from inbetween the bowl assemblies.
