Submersible Pump and Motor

Submersible Pump and Motor

Salient Features

  • Fabricated stainless steel impellers and diffusers for corrosion resistance
  • Heavy duty stainless steel structure to assure permanent alignment of all the components in order to increase run time and trouble-free operation
  • PTFE floating neck ring, ceramic guide journal sleeve (tungsten-carbide on request) and Nitrile rubber fluted bearing to ensure durability against wear for long-lasting constant performances and product reliability
  • Compact, reliable and suited to operate in horizontal position
  • Built-in check valve to protect the pump against water hummer risk
  • External stainless steel sleeve to improve stiffness and assure permanent alignment of all the components
  • Radial models with double reinforcement rings and mix-flow models longer than 3 m are equipped with tungsten-carbide (widia) upper journal sleeve and with an intermediate tungsten-carbide (widia) journal sleeve plus special intermediate split cone nut
  • The hydraulic design is such to enhance the overall efficiency thus reducing energy consumption and making the pumping systems more cost effective
  • Encapsulated Motors are Water lubricated thrust and radial bearings enable a maintenance free
  • Motors are designed with special diaphragm ensures pressure compensation inside the motor. The motors are filled with special FES91 fluid, providing frost protection down to -15°C Storage temperature.
