The AZPF-12-019RRR20KB pump is manufactured by Bosch Rexroth for the AZPF External High Performance Gear Pumps series and is intended to move hydraulic fluid in automated machinery. It displaces 19 cm³ per revolution, setting the flow rate for each shaft turn. Clockwise rotation is specified so it mates with drive arrangements that follow right-hand orientation. The mounting flange conforms to SAE J744 82-2 (A) to fit common motor adapters, and a pilot diameter of 82.55 mm centers the body in the flange recess. A bolt circle of 127 mm together with hole centers of 106.4 mm positions the fasteners, while M6 holes 13 mm deep fix the unit securely. The pump weighs 3.9 kg, allowing manual handling during installation.
The hydraulic section withstands 210 bar continuously to support normal circuit demand, while an intermittent limit of 230 bar handles temporary overloads and a peak rating of 250 bar absorbs short pressure spikes. A minimum operating speed of 500 rpm below 100 bar keeps internal bearings lubricated and prevents cavitation. The input shaft offers a usable spline length of 21.8 mm so full torque can be transmitted from the prime mover without fretting. An FKM shaft seal resists oil and heat, reducing leakage throughout long duty cycles. These specifications define the performance envelope and mechanical interfaces required for reliable integration into industrial hydraulic systems.
