Internal Gear Pump PGH5-3X/063LR11VU2 - Bosch Rexroth R901260687

A variable-speed drive only saves energy if the pump delivers cleanly across the whole speed range and imposes no load cycle limitation. The internal gear pump PGH5-3X/063LR11VU2 with constant displacement is built for that and delivers up to 189 l/min.

Benefits

• Optimised for variable-speed drives, with no load cycle limitation.
• Up to 189 l/min at a maximum of 315 bar operating pressure, size 63.
• Low noise and low pulsation level from the internal gear principle.
• Through-drive fitted, so a second pump can be added without a distributor gearbox.
• 43.48 kg in a cast iron housing, FKM seals and a geared shaft 38-4 to ISO 3019-1.

Applications

In industrial plants running an open circuit, a speed-controlled fixed displacement pump increasingly replaces the combination of variable pump and unregulated motor, because the drive draws less at part load and runs more quietly. The 2-hole mounting flange 127-2 to ISO 3019-1 and the geared shaft end follow the standard, so existing attachments still fit. With special fluids the permitted operating pressure drops to 220 bar, which has to be allowed for in the design.
