Water Pumps › Openwell Submersible Pumps
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.
- oot – 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.
Salient Features Of Openwell Submersible Pumps
- Dynamically balanced rotating parts.
- Flatter efficiency curve for efficient operation.
- Non-overloading power characteristic for safety of motor.
- Replaceable wearing parts.
- No need of priming or foot valve.
- Water shower arrangement for surface application.
- Highly durable water cooled rewindable motor.
- Single shaft for pump & motor ensures permanent correct line alignment.
- Foundation & installation not required.
- Stainless Steel Motor Body.
- Gun Metal bush bearing.
- Noiseless Operation.
- Maintenance free water lubricated bushes.
