Offshore Submersible Pump Features

  1. Power supply cable: Flowdirect hold popular cable sizes in stock.
  2. Non-return valve: Spring loaded or gravity, non-clogging and canting. Short closing time avoids water hammer.
  3. Threaded Stud connections: Rapid and low cost dismantling with stainless steel studded connections.
  4. Bearing: water resistant bearings. High resistance against sand and vibration.
  5. Impellers: Wear resistant impellers of high quality bronze or stainless steel. Exact pump duties can be achieved through hydraulic modifications.
  6. Stationary and rotating wear rings: Wear resistant, replaceable stationary and rotating rings.
  7. Pump Casing: Materials available for all applications.
  8. Engineered coupling: Simple connection between pump and motor.
  9. Mechanical shaft seal and double lip seal system: highly wear resistant seal for a long life and integrity.
  10. Pump and motor shaft: High grade stainless steel of robust construction.
  11. Bearing sleeve: Double bearing sleeve made of synthetic carbon with spiral groove for cooling and lubrication of the motor.
  12. Motor cooling: Motor sized for pump max power. Option of temperature control in the motor by internal cooling circuit.
  13. Motor shroud: stainless steel.
  14. Counter axial thrust bearing: Resists axial up-thrust.
