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.

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.
