Internal Gear Pump PGH5-3X/160RE11WU2 - Bosch Rexroth R901225225

Some power units have a mounting flange to ISO 3019-1 but a coupling for a cylindrical shaft. The internal gear pump PGH5-3X/160RE11WU2 serves exactly that mix: shaft end cylindrical Ø 40 mm with fitting key to ISO 3019-2, mounted on a 2-hole flange 152-2 to ISO 3019-1. Flow reaches 480 l/min.

Benefits

• Cylindrical shaft Ø 40 mm with fitting key to ISO 3019-2 for jaw couplings.
• 2-hole mounting flange 152-2 to ISO 3019-1.
• Flow up to 480 l/min, size 160, constant displacement.
• Operating pressure to 210 bar, and to 145 bar on HFC.
• Through-drive included, clockwise rotation.
• 52.4 kg in weight, NBR seals.

Applications

This combination comes up when replacing a pump in a plant that grew over time, where flange and coupling follow two different standards. It works in the open circuit of power units running HFC fluid, for instance in foundries and rolling mills. Internal gearing keeps running quiet over long duty periods.
