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
- 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.
Features
- 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.
Application
Industrial & public water supply schemes, Domestic water supply, Lift irrigation schemes. Drip/ Sprinkler Irrigation schemes, fire lighting, booster application, cooling water. Circulation, Ornamental fountain installation and air conditioning plants. Dewatering of mines, offshore, platforms, etc. |
