Openwell or borewell submersible?
They look alike in a catalogue, but suit very different wells.
Farmers often ask whether they can use a borewell submersible in an open well, or the other way round. The short answer is no, and the reason is the shape of the pump.
An openwell submersible is shorter and wider, built to sit in a wide well with water around it. Its motor is cooled by the surrounding water and it draws from the side. It handles some silt and debris, which open wells always have, and it can be lifted out by rope for servicing. Our 2 HP openwell model suits wells up to 15 m deep.
A borewell submersible is long and narrow, made to fit inside a 4, 6 or 8 inch casing pipe. Water flows past the motor in a narrow gap to cool it, so it is designed for clean groundwater. In an open well, without that guided flow, the motor can overheat. In a sandy bore, the impellers wear quickly.
The right choice depends on your well. Open wells with water within 15 m of the surface are better served by an openwell pump, or even a monoblock if the water is within 6 m. For deep bores, a borewell submersible is the only option. Tell us the well type and depth and we will match it.
