Openwell Monoset Pumps

Features

  • Induction motors are easily re-windable using multi layer PVC insulated wire for better reliability.
  • Motor filled with water gives better cooling to winding as well as bush.
  • Self-aligned Teflon OR carbon Stainless steel thrust bearing which withstands high axial thrust load in water lubrication.
  • Electrically designed to lower power consumption and operating cost.
  • Non-magnetic, corrosion-resistant high-grade stainless steel stator body.
  • Water-filled motor is available in capacitor start and run design.
  • Gun Metal bush is made with additional centrifugal molding process and 2 % Nickel is added.
  • Superior designed Noryl impellers and diffusers give higher hydraulic performance and greater efficiency and provide higher resistance against wear and tear from sand and other impurities.
  • Stainless steel strainer prevents particles over a certain size from entering the pump.
  • Pumps are available with non-return valve to reduce the backpressure of water when it is switched off.
  • Impeller and Bowl are accurately machined by CNC machine to ensure high dimension accuracy.
  • Rubber bush and SS hard chrome sleeve increase wear-resistance against sand.
  • Lightweight, compact and robust construction design.

Applications

  • Sprinkler and drip irrigation.
  • Urban and Rular resident water Supply and Industries.
  • Fire fighting system
  • Agriculture
