Open well submersible pumps
Open well 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 for Open well Submersible Pump
- 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 Open well Submersible Pump:
- 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.
- Foundation & installation not required.
- Stainless Steel Motor Body.
- Gun Metal bush bearing.
- Noiseless Operation.
- Maintenance free water lubricated bushes.
Application Of Openwell Submersible Pump:
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.
Domestic Monoblock Pumps
Domestic Monoblock Pumps are replacing centrifugal pumps at a number of places because of some of the inherent advantages, such as.
- Low cost.
- No centrifugal switch
Salient Features of Domestic Mono Block Pumps
- Uni-casing no air lock problem.
- Balanced and rigged construction.
- No centrifugal switch.
- Less operational and maintenance cost.
- Application Of Domestic Mono block Pumps
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.
Construction of Domestic Monoblock Pumps
Wet squirrel cage induction type, water cooled, water lubricated motor. All bearings are water lubricated.
