Internal Gear Pump PGH5-3X/080RR11VU2 - Bosch Rexroth R901147130

On variable-speed drives the torque reverses constantly and a fitting key becomes the weak point. The PGH5-3X/080RR11VU2 therefore transmits it through a geared shaft 38-4 with 17 teeth at 12/24 DP, delivers up to 240 l/min and works up to 315 bar.

Benefits

• Geared shaft 38-4, 17T 12/24 DP to ISO 3019-1, form-fit torque transmission without a fitting key.
• 240 l/min flow at the constant displacement of size 80.
• 315 bar operating pressure, 220 bar with special fluids.
• FKM seals for hydraulic fluid HLP and higher oil temperatures.
• Through-drive available, a second pump runs on the same drive shaft.
• 42.87 kg, clockwise rotation, 2-hole mounting flange 127-2.

Technical data

Application

The internal gear pump feeds power units on machine tools, presses and test rigs in an open circuit. The cast iron housing and the geared shaft suit variable-speed drives that start and brake frequently. The through-drive allows a further pump for an auxiliary or pilot circuit to be flanged on.
