1Phase Openwell - Horizontal

Have Question?

Openwell pumps are ideally suitable for where there are wide fluctuations in water level. This works under water and it rests at bottom of the well. Hence, suction and priming problems do not arise. Pump volute chamber is designed to give the best possible hydraulic efficiency. Dynamically balanced impellers offers vibration free operation with long life.

Open well Submersible pumps are found in many applications, and are used for Domestic and communal water supply, Drinking water supply, Irrigation purpose, Agricultural use, Construction site, Cooling water circulating system, Water distribution to high rise buildings and Industries.
