The P2V7/63-94C0+V7/10-14C0RE07+01E4 pump belongs to the PV7 Adjustable Vane Pumps series from Bosch Rexroth and serves in hydraulic automation where variable delivery and a compact dual-stage design are required. Stage 1 has a displacement of 94 cm³ and stage 2 offers 14 cm³, so the assembly can supply high or low volume as the circuit demands. When the shaft turns at 1450 rpm, stage 1 delivers 136 l/min while stage 2 delivers 21 l/min, providing separate flow paths for simultaneous actuators. Stage 1 is rated for an output pressure of 80 bar, whereas stage 2 withstands 160 bar, allowing the smaller section to feed high-pressure control lines. Mineral oil HLP according to DIN 51524-2 is the specified working fluid to ensure vane lubrication and sealing. Suction conditions must stay between 0.8 bar and 2.5 bar absolute to prevent cavitation, and the rotating group may run up to 1800 rpm without overspeed.
Leakage at zero stroke for stage 1 is limited to 5.3 l/min, keeping standby losses low during pressure-holding cycles. The internal drain line may see up to 2 bar, so the reservoir return must stay unrestricted. Continuous operation is permitted down to 900 rpm, which supports energy-saving speed control when full output is not required. Installation uses a 4-hole flange that follows ISO 3019-2, allowing quick interchange with other vane pumps on standard motor adapters and keeping reaction forces centered on the drive shaft. Pressure and suction ports differ by section: stage 1 employs an SAE flange interface defined in ISO 6162-1 for the larger flow, while stage 2 uses a pipe thread in accordance with ISO 228-1 to suit smaller line sizes. This separation simplifies plumbing for mixed-pressure circuits, maintains correct fitting strength at each pressure level, and streamlines maintenance with readily available hardware.
