Openwell submersible pumps are replacing centrifugal pumps at a number of places because of some of the inherent advantages, such as.
- No separate foundation is required.
- Cooling is much better & hence longer life.
- Convenient to move from place to place.
- Foot – Valve is not required.
- Suction head is eliminated.

Design - Openwell Submersible Pumps |
|
No Foundation – No pump house required. |
|
|
|
Pump operates under water, hence no foot valve – no priming – no suction problems- less possibility of burn-out of motor. |
|
|
|
Long life due to, cast iron construction – water lubricated journal & thrust bearings – dynamically balanced all rotating parts – motor designed to withstand wide voltage fluctuation. |
|
|
|
For safety, earthing terminal is provided. |
