4HS 4” borehole pumps are designed for the extracting of water from 4” boreholes and wells. These variable speed submersible borehole water pumps are suitable for applications including water supply, sprinkler irrigation, pressure boosting and geothermal systems.

Supplied as a ready to use kit for the user’s ease, 4HS borehole pumps come as standard with a variable speed inverter with surface mounted control module and pressure transducer. The beauty of this is that they are extremely energy efficient. As the motor speed can be changed to maintain a constant pressure regardless of water demand, the borehole water pump is operated only when required, without wasting energy and also extends pump life. It also starts/stops the pump gently to reduce mechanical stress and protects it from surges, under/overload and dry running.

Unlike other borehole pumps, the 4HS pump’s inverter module is built in. This removes the chances of interference with other devices which sometimes occurs where the inverter is separated from the motor.

These submersible borehole water pumps are constructed in AISI 304 Stainless Steel for protection against corrosion and long performance life.
