Rated pressure is 250 bar, intermittent pressure 280 bar, peak pressure up to 300 bar.
What is the maximum speed?
+
-
Maximum continuous speed is 2800 rpm.
Is this pump interchangeable with the original Rexroth?
+
-
Yes, it has the same mounting dimensions, shaft, ports and flange as the original, so it can be directly replaced.
- This pump is a Rexroth AZPGG series twin external gear pump, a fixed-displacement hydraulic gear pump in size series 22. It features a two-stage pump configuration, with the front pump having a displacement of 32 cm³/rev and the rear pump 22 cm³/rev. It can simultaneously supply two independent flow paths to the hydraulic system, making it suitable for multi-circuit hydraulic control applications.
- The pump has a rated continuous operating pressure of 250 bar, with a short-term intermittent overload pressure of up to 280 bar and a peak pressure of 300 bar. The maximum allowable speed is 2800 rpm, and the minimum operating speed is adjustable between 500 and 1200 rpm depending on the pressure range. The internal design features a sliding bearing structure, enabling dry start capability and ensuring stable operation. The shaft extension is configured as an RDC standard SAE spline shaft; the flange and connection use a 0707KB specification SAE two-hole flange; the oil ports employ a square flange design compliant with ISO 8434-1; and the seal version is S0081 (NBR material).
- Suitable media include mineral hydraulic oils compliant with DIN 51524, with an operating viscosity range of 12–800 mm²/s (recommended 20–100 mm²/s) and an operating temperature range of -20°C to +80°C. Featuring a compact overall design, high pressure rating, and reliable service life, this valve is primarily used in industrial hydraulic power units, construction machinery, injection molding machines, and various medium- to high-pressure hydraulic systems requiring dual-line oil supply.
