The AZPF-12-019LRR12MA gear pump is part of the AZPF External High Performance Gear Pumps series from Bosch Rexroth and is intended for fixed-displacement hydraulic automation. It moves 19 cm³ per revolution to supply a precise flow rate to cylinders or motors. The counter-clockwise rotation direction aligns with drives that turn the shaft in that orientation. A maximum speed of 3000 rpm supports high flow demands, while a minimum of 500 rpm at pressures below 100 bar permits slow-speed circulation during standby or low-load conditions. The unit mounts with an SAE J744 82-2 (A) flange; the 82.55 mm flange diameter centers the housing, and a mass of 3.9 kg keeps handling straightforward.
The hydraulic circuit can be maintained at 210 bar continuously, elevated to 230 bar for intermittent duty, and withstand 250 bar peak surges without structural damage. A pressure port cut 16 mm deep with a 7/8-14 UNF-2B thread secures the outlet line and resists loosening under pulsation. The suction side uses an 11/16-12 UNF-2B thread and a 19 mm depth to encourage unimpeded fluid entry and minimize cavitation. NBR sealing elements contain the oil and resist common hydraulic fluids, preserving service life in temperature-controlled reservoirs. Together these characteristics define operating limits and connection geometry for reliable integration into hydraulic machines.
