Pumps: A different model for every need.

The widest range of positive displacement pumps.


Pumping is one of the most important stages during recovery operations. Type of oil and its viscosity, work environment and storage capacity are some of the parameters operators must assess to choose a pump. There are different families of pumps but only one can handle high viscosity and waste fluids: Positive Displacement Pumps

Sedosr suggests you several type of positive displacement pumps.

  • Archimedes’ Screw
  • Lobe
  • Diaphragm
  • Peristaltic

Please let us advise about the proper pump for your application.



Arquimedes’ Screw Pumps

Completely engineered and manufactured by SEDOSR ENGINEERING S.L., SEDOSR PUMP ONE are positive displacement pumps able to work with the most aggressive and viscous fluids even in the presence of solids. Being a positive displacement pump, it can keep flow rate almost constant while increasing delivery head; this is the main difference with submersible centrifugal pumps which flow rate decreases dramatically while increasing pressure.

Disassembly is an easy operation due to the reduced number of bolts that fit the pump. The main parts of the pump are one-piece manufactured so have no bolts.

Fully manufactured in stainless steel, AISI-316, its sealing disc is FPM (VITON®) rubber coated and allows a perfect fitting to the Archimedes screw. Internal finishings make use of the latest technology for copolymer coatings (PTFE, TEFLON®), thus internal friction is minimized as well as hydraulic pressure and discharge pressure loss and energy consumption.

Finally, the considerable discharge pressure allows long distance pumping.

Examples of applications:

  • On-board pump in Oil Recovery Systems
  • Emergency pumping of hydrocarbons of any viscosity and emulsions
  • Emergency bilge pump
  • Offloading and ballasting, as an auxiliary pump.
  • Molasses pumping
