The PV7-1X/40-71RE37MC0-08 pump belongs to the PV7 Adjustable Vane Pumps series and is produced by Bosch Rexroth for hydraulic automation systems that require variable flow. A displacement of 71 cm³ per revolution determines the volume moved each shaft turn, while a maximum flow of 104 l/min at 1450 rpm and 10 bar defines circuit capacity. Flow is adjusted in 25 l/min steps per control turn at the same speed, giving precise output regulation. The pump supports a maximum operating pressure of 80 bar and maintains a minimum outlet pressure of 20 bar to keep the vanes seated. Drive requirements peak at 16.5 kW under full pressure, and the shaft must accommodate up to 280 Nm of torque.
Mounting uses a four-hole flange that complies with ISO 3019-2, allowing direct attachment to standard motor faces. Pressure fluid exits through a G1 port conforming to ISO 228-1, and the inlet is a DN38 connection matching SAE 1 1/2 in threads; both simplify hose and fitting selection. The pump is designed for clockwise rotation. Internal leakage at zero stroke is 4 l/min to lubricate and cool internal parts, and the drain line must stay below 2 bar because this is the maximum permitted leakage oil pressure. Fluid cleanliness should reach ISO 4406 code 20/18/15 to protect the vane set, and the assembled unit weighs 30 kg, a figure important for handling and support.
