AZ-P-F-12-011-RQR12PB

The AZ-P-F-12-011-RQR12PB pump is manufactured by Bosch Rexroth within the AZPF External High Performance Gear Pumps series. It provides consistent hydraulic flow for automation circuits that rely on fixed-displacement units. A clockwise direction of rotation aligns the drive with standard right-hand power take-offs found on industrial engines. Each revolution moves 11 cm³ of oil, so system designers can calculate output based on shaft speed. The drive shaft uses a parallel keyed interface in accordance with SAE J744 16-1 A, delivering positive torque transmission without requiring splined couplings. A shaft diameter of 15.875 mm partners with the keyed form to fit readily available hubs. Installation is handled by a 2-bolt SAE J744 82-2 (A) mounting flange, which standardizes the bolt pattern for common bell housings. The flange diameter is 82.55 mm, setting the pilot size that centers the pump and maintains alignment between the drive prime mover and the hydraulic section.

For hydraulic cycles that momentarily exceed nominal load, the unit tolerates an intermittent pressure of 260 bar, allowing brief spikes without internal gear damage. The pressure outlet is machined with a 7/8-14 UNF-2B thread 16 mm deep, providing a high-strength connection for the discharge line, while the suction port carries the same 7/8-14 UNF-2B thread and depth to simplify hose selection and inventory. Operational ambient limits differ by seal material: pumps equipped with NBR seals run between −30 °C and +80 °C, whereas versions fitted with FKM seals extend the range to −20 °C through +110 °C, supporting deployment in both cold storage plants and high-temperature power units. A weight of 3.6 kg keeps handling manageable during assembly or field replacement, so a single technician can position the pump without lifting aids.
