Internal Gear Pump PGH5-3X/080RE11WE4 - Bosch Rexroth R901349331

Sizing a variable-speed hydraulic power unit calls for a pump that stays quiet and low in pulsation across the whole speed range. The PGH5-3X/080RE11WE4 internal gear pump in size 80 delivers up to 240 l/min at a maximum operating pressure of 315 bar and works without load cycle limitation.

Advantages

• Constant displacement in size 80 with up to 240 l/min, enough oil for power units with high demand in an open circuit.
• Maximum operating pressure of 315 bar, 220 bar with special fluids, released for the hydraulic fluid HFC.
• Designed for variable-speed drives, so there is no limit on the number of load cycles.
• Through-drive included, a second pump can be mounted directly without an extra gearbox.
• Cylindrical shaft end Ø 40 mm with fitting key and a 4-hole mounting flange 160B4SW, both to ISO 3019-2, for a standard-compliant fit to the drive motor.
• Cast iron housing and NBR seals at a weight of 42.8 kg.

Application

The pump feeds hydraulic power units in an open circuit, for example in presses, injection moulding machines and test rigs. On a speed-controlled motor the flow follows the actual demand of the machine, which lowers power draw during partial load. In systems running on the fire-resistant fluid HFC the reduced operating pressure of 220 bar applies.
