Hydraulic oil separatorHydraulic oil separator

Hydraulic oil separator - EXP

The EXP hydraulic oil separator allows the separation of hydraulic fluids contained in a tank. It looks like a synthetic rubber bladder that is perfectly deformable. It can be placed either inside or outside the tank, depending on the needs. Real auxiliary tanks, they can be made flat or shaped.

The product will compensate for volume variations. These variations can deteriorate the characteristics of the oil and the hydraulic system components. The compensators are permanently installed within the system, making it autonomous, and require no maintenance.

This hydraulic oil separator allows: 

  • To avoid emulsion, air in the oil, condensation in the tanks, or pollution of the oil by dust
  • To eliminate turbulence and the risk of leaks, whatever the orientation of the tank. 
  • The operation in water immersion

These hydraulic compensators are available as standard.  However, they can also be custom-made according to the dimensions of your tanks and the volume to be compensated. 

In addition, for the compensation of oils of more common preservatives, we find the STP rubber bag transformer.
