The submerged cargo pump
The submerged cargo pump anatomy detail wide 2.png

The Framo cargo pump is a vertical single stage centrifugal pump powered by a hydraulic motor for safe and efficient operation.

All our cargo pumps are made in stainless steel material and designed with a smooth and easy-to-clean surface with a limited number of flanges which gives a superior ability to pump any liquid.

Design features

  • Vertical single stage, single suction impeller, axially balanced
  • Robust hydraulic drive with short and stiff drive shaft
  • Fail-safe design; Lubrication and cooling of pump by the hydraulic driving oil medium
  • Pump material stainless steel
  • Concentric hydraulic pipes for maximum safety
  • Cofferdam, ventilated to the atmosphere, protecting the entire pump
  • Mechanical seal against hydraulic oil
  • Double lip seal against cargo, only exposed to static pressure
  • Anti-rotation brake; loading through the pump
  • Smooth pump exterior; self draining and easy to clean

The Framo cargo pump is easy to operate. The hydraulic drive provides for a remote and local stepless capacity control through the Speed Torque Control (STC) valve on the pump's top plate. The cargo pump can pump anything liquid, regardless of specific weight or viscosity.

It is impossible to overload or to over-speed the pump. The STC valve auto-matically regulates hydraulic oil pressure and flow to the hydraulic motor according to the given discharge situation.

The pump design allows operation with a minimum of liquid in the tank which saves time spent for drainage and tank cleaning. The Framo cargo pump has a built-in efficient stripping system.

Condition based maintenance
Seal monitoring is performed from the cargo pump top plate by purging the cofferdam.

Replacement of wear and tear parts is easily done from inside of the tank without interfering with the hydraulic section.
