AZPF-12-019RQR12MA SO022

The AZPF-12-019RQR12MA SO022 gear pump belongs to the AZPF External High Performance Gear Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation where consistent oil flow is needed. Its displacement of 19 cm³ per revolution sets the nominal volume of fluid delivered per shaft turn, supporting compact power units on mobile or industrial machinery. A maximum operational speed of 3 500 rpm lets the pump accept high-speed prime movers without cavitation, while a minimum speed of 500 rpm at pressures below 100 bar keeps internal lubrication effective during idle or low load cycles. The unit is configured for clockwise rotation so drive coupling direction is fixed for right-handed layouts. Installation is simplified by a two-bolt mounting flange with an 82.55 mm diameter pattern per SAE J744 82-2, allowing direct attachment to standard motor adapters. At 3.9 kg, the housing can be handled by one technician during maintenance or replacement.

The pump tolerates ambient temperatures from −30 °C to +80 °C, enabling reliable service in outdoor or foundry environments. A maximum intermittent pressure rating of 170 bar supports continuous duty at typical system loads, while the capacity to endure pressure peaks up to 300 bar protects the circuit during transient shocks. The pressure outlet uses an 11/16-12 UN-2B thread with a 19 mm depth so the high-pressure line can be sealed with an O-ring face fitting that resists vibration. On the inlet side, a 7/8-14 UNF-2B thread with a 16 mm depth provides a low-restriction suction path that minimizes aeration at high speeds. All ports follow the UN interface defined by ISO 11926-1, ensuring parts compatibility across North American and international hose assemblies. These features combine to keep the pump stable, leak-free, and ready for demanding hydraulic motion control loops.
