Internal Gear Pump PGH5-3X/080LR11VU2 - Bosch Rexroth R901260688

A variable-speed drive saves energy but asks the pump to cover a wide speed band. The PGH5-3X/080LR11VU2 internal gear pump in size 80 is laid out for that, supplies up to 240 l/min and works up to 315 bar operating pressure.

Benefits

• Constant displacement in size 80 with flows up to 240 l/min.
• Maximum operating pressure 315 bar, and 220 bar with special fluids.
• Low noise and low pulsation from the internal gear design, with no load cycle limitation.
• Geared shaft 38-4, 17T 12/24 DP to ISO 3019-1 and a 2-hole mounting flange 127-2 according to ISO 3019-1.
• Through-drive included, so a second pump can be mounted behind it.
• FKM seals for HLP hydraulic fluid, counterclockwise rotation, 45.53 kg mass.

Applications

The pump feeds power units in open circuit, for example on machine tools, presses and test rigs. On a variable-speed drive, delivery follows demand, so less oil is circulated during holding phases and less heat is generated. The through-drive allows a second pump on the same shaft line.

Manufacturer
