OPENWELL PUMPSETS


openwell-pumpsets

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 - OPENWELL SUBMERSIBLE PUMPS

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.

Application

Domestic, Garden, Irrigation, Drip & Sprinkler irrigation, Public water supply, Industrial & rural water supply.

Special Features

  • No suction & priming problems
  • No need of pump house
