AZPF-11-005LCB20MB

The AZPF-11-005LCB20MB gear pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation systems where compact, fixed-displacement flow is required. Its geometric displacement of 5.5 cm³ per revolution governs the volume delivered with each shaft turn, helping designers calculate circuit flow. A maximum rotational speed of 4000 rpm permits coupling to high-speed electric or engine drives without overspeeding the pumping group. Counter-clockwise rotation is specified so the unit mates correctly with left-hand prime movers and maintains correct inlet and outlet orientation. The tapered 1:5 drive shaft provides positive torque transfer while facilitating easy removal during service. A continuous pressure rating of 250 bar supports steady operation under normal load, and the intermittent pressure limit of 280 bar accommodates short duration surges created by rapid actuation cycles.

The pump’s peak pressure capability of 300 bar allows it to withstand brief transients that can occur when valves shift abruptly in hydraulic machinery. Fluid ports are formed as a rectangular flange identified as code 20, simplifying rigid tube connections in manifold blocks. The mounting flange measures 80 mm in a rectangular pattern, giving a standardized interface for direct attachment to motor adapters or machine frames. Mounting holes are tapped M6 to a depth of 13 mm, providing sufficient thread engagement for secure fastening. NBR sealing material, declared with code M, resists common hydraulic oils and maintains integrity across typical temperature ranges. A mass of 3.2 kg keeps the assembly light enough for hand installation while still providing the structural stiffness expected from a high-performance external gear pump.
