Rexroth pumps up the power

20 March 2008

Rexroth has upped pumping power with the launch of its PGH Series 3X internal gear pump. Based on the predecessor model the revised PGH Series 3X operates at a nominal pressure of 315bar, or 350bar in intermittent operation.

Its speed range has also been extended for all sizes up to 3,000rpm. In the lower speed range, up to 200rpm, the new power pump is suitable for pressure-holding functions and closed-loop position control.

Designed in particular for variable speed drives in stationary and mobile applications, Rexroth’s PGH Series 3X is available in two frame sizes covering a range from 20 to 250ccm, adding to the previous PGH Series 2x pumps at these sizes. A new feature on the PGH Series 3x is a standard test port that simplifies bleeding during commissioning. This test port also allows for condition monitoring systems to be attached for condition-related servicing of the complete drive system.
