The PV7-2X/20-25RA01MA0-05 vane pump is produced by Bosch Rexroth and belongs to the PV7 Adjustable Vane Pumps series. Designed for hydraulic automation, it delivers variable volume to actuators and control valves in machinery. A displacement of 25 cm³ per revolution lets the pump supply moderate output while keeping drive power low. At maximum, it moves 45.0 l/min so circuits can cycle quickly under load. The pumping group tolerates 100 bar operating pressure, matching medium-pressure systems common in industrial equipment. Service speed tops out at 1800 rpm, enabling direct coupling to standard electric motors. Suction line pressure must stay above 0.8 bar to prevent cavitation, and internal leakage is relieved through a drain port limited to 2 bar. The factory sets zero stroke pressure at 25 bar to provide a stable standby value, and the shaft is configured for clockwise rotation.
For installation, the housing uses an ISO 3019-2 four-hole mounting flange that aligns with numerous power unit plates, and fluid lines connect via ISO 228-1 pipe threads for straightforward assembly. The pump transmits up to 110 Nm of torque, permitting it to start under full load without overstressing the drive shaft. A weight of 11.4 kg allows single-person handling during maintenance. Sealing elements are made from NBR, so the unit remains compatible with standard mineral oil while resisting common temperature ranges. The specified hydraulic medium is HLP oil according to DIN 51524, which maintains film strength throughout the operating window. System cleanliness must not exceed ISO 4406 (c) 19/16/13 to minimize wear in the vane set and control sleeve. These features combine to support reliable duty cycles in automated presses, test rigs, and material handling stations.
