FAQ

What type of hydraulic fluid is compatible with the FKM seals (MB code)?

FKM (Viton) seals are compatible with a wide range of fluids, including mineral oils (HL, HLP), synthetic esters (HFD-U), and some fire-resistant fluids. Always check your system’s requirements and the fluid manufacturer’s recommendations.

What is the typical maximum operating pressure for this pump series?

Pumps in the Rexroth PVU1 series generally have a maximum continuous operating pressure of up to 160 bar (approx. 2300 PSI), depending on the specific model and operating conditions. Refer to the official datasheet for precise limits.

How do I confirm the correct direction of rotation upon installation?

The type code ‘R’ indicates clockwise rotation when viewing the shaft end. Often, an arrow is also cast or stamped onto the pump housing. Ensure the prime mover (electric motor) rotates in the same direction before coupling the pump.
