The PV7-1X/63-71RE07MC0-16 is a variable displacement vane pump from Bosch Rexroth in the PV7 Adjustable Vane Pumps series intended for hydraulic automation circuits that need controlled flow and moderate pressure. Its clockwise rotation aligns with standard electric motor drives, simplifying coupling. A displacement of 71 cm³ per revolution establishes the volume moved each shaft turn, enabling predictable flow calculation. At 1450 rpm the pump delivers up to 108 l/min, covering medium size actuator groups. Continuous operation is permitted at system pressures up to 160 bar so it can power clamps or presses within that range. The speed window begins at 900 rpm, letting the unit maintain lubrication at low idle, and reaches 1800 rpm for higher demand cycles. Maximum drive power of 33 kW at 1450 rpm defines the motor rating required to prevent overload.
Drain oil is routed back to tank at pressures no higher than 2 bar to avoid excess load on the shaft seal. Suction conditions must stay between 0.8 bar absolute and 2.5 bar absolute so vapor cavities do not form and inlet noise is minimized. A peak torque capability of 440 Nm accommodates cold-start viscosity and rapid pressure rise. The pressure port uses an SAE 1 1/4 in (DN32) connection, allowing direct fit to common rigid lines, while the suction port is an SAE 2 in (DN51) size that reduces inlet velocity. NBR sealing material provides compatibility with standard mineral oils at typical temperatures. The assembly weighs 37 kg, a consideration for mounting plates and support brackets.
