The PV7-2X/20-25RA01MA0-10 belongs to the PV7 Adjustable Vane Pumps series from Bosch Rexroth and is intended to supply variable flow in hydraulic automation circuits. It moves 25 cm³ of fluid per revolution, operates safely up to 100 bar, and can deliver as much as 45.0 l/min when fully opened. Each full turn of the setting spindle changes output by 14 l/min, giving maintenance staff a quick way to fine-tune actuator speed. Clockwise rotation matches common motor directions, while a cylindrical keyed shaft defined by ISO 3019-2 permits direct coupling to standard drives. Continuous service is possible down to 900 rpm, and the shaft can accept up to 110 Nm, providing reserve for cold-start viscosities or pressure spikes.
The pump is designed for mineral oil HLP specified by DIN 51524, ensuring compatibility with its internal wear surfaces. Pipe-thread ports following ISO 228-1 allow straightforward connection to line tubing and manifolds. Case drainage can be routed through filters because the drain line tolerates up to 2 bar back pressure, while the suction side must not exceed 2.5 bar to protect the vanes. Internal leakage is limited to 2.5 l/min to maintain volumetric efficiency across the adjustment range. All dynamic seals are made from NBR to balance cost, oil compatibility, and temperature capability, and the assembled unit weighs 11.4 kg, light enough for direct mounting on small power packs.
