The AZPF-12-019RRR12MA gear pump is part of the AZPF External High Performance Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits. It delivers a geometric displacement of 19 cm³ per revolution, giving predictable flow for fixed-displacement systems. Clockwise rotation matches drive layouts that turn the shaft in the standard direction. Installation uses an SAE J744 82-2 (A) two-bolt flange, so alignment with common motors and bell housings is straightforward. Fluid enters through a 1 1/16-12 UN-2B inlet port, while the discharge line attaches to a 7/8-14 UNF-2B outlet port; both ports follow the SAE ORB UNF-2B standard to allow O-ring boss fittings that minimize leakage. An NBR seal set contains the fluid against the shaft and housing, providing compatibility with typical mineral oils.
The pump operates in ambient temperatures from −30 °C to 80 °C, allowing use in cold outdoor machinery or warm factory cells without added conditioning. A continuous working pressure of 210 bar supports steady duty cycles, with allowance for 230 bar during intermittent load spikes and short peaks up to 250 bar to absorb pressure shocks. Maximum shaft speed reaches 3000 rpm at rated outlet conditions, enabling high volumetric throughput, while stable suction is maintained down to 500 rpm at a fluid viscosity of 25 mm²/s so low-speed functions remain controllable. The assembled unit weighs 3.9 kg, light enough for single-person mounting yet robust for industrial service.
