Our Product / Services
Founded in Gujarat(India), the company has garnered wide appreciation for its seamless quality products and client centric approach. Combining our expertise with the technology that we possess, we take the responsibility to deliver utmost quality Openwell Submersible Pump to the customers.
Intro :
C.R.I. Openwell Submersible Pumpsets are Ideally suitable for Openwells or Tanks where a wide fluctuation of water level occur. This work under water and rest at the Bottom of the well or Tank. Hence Suction and Priming problem will not arise. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency. Motor sealing is made by polymers, rings, oil seals and sand guard to avoid ingress of well water / sand into the motor. Pressure equalizing rubber diaphragm is provided to guard the pressure and volume variation of water inside motor. Motor must be filled with clear, cold, drinking water as detailed in our operators manual. Three -phase motor requires an adequate motor protection control panel.
