Internal Gear Pump PGH5-3X/080RR11WU2 - Bosch Rexroth R901296758

Variable-speed drives require the pump to deliver evenly across a wide speed range. The internal gear pump PGH5-3X/080RR11WU2 is laid out for exactly that, delivering up to 240 l/min at a maximum of 315 bar into the open circuit from its constant displacement of size 80.

Advantages

• Up to 240 l/min at a maximum of 315 bar operating pressure in the open circuit.
• No load cycle limitation, so the pump may change between pressure levels in continuous duty.
• Operating pressure up to 220 bar with special fluids, released for HFC hydraulic fluid.
• Through-drive included, a second pump can run on the same drive shaft.
• Geared shaft 38-4, 17T 12/24 DP according to ISO 3019-1 with a 2-hole mounting flange 127-2.
• Weight of 42.6 kg with clockwise rotation, cast iron housing with NBR seals.

Application

The pump feeds power units in the open circuit, for example on machine tools, presses and test rigs. The through-drive allows a second pump to be mounted when a further circuit has to be fed from the same drive. With its release for HFC up to 220 bar it also suits installations where fire-resistant fluid is used. Clockwise rotation has to be observed when coupling the pump to the motor.
