PV7-1X/40-71RE37MD0-08

The PV7-1X/40-71RE37MD0-08 adjustable vane pump belongs to Bosch Rexroth’s PV7 Adjustable Vane Pumps series and supplies controlled oil flow in hydraulic automation circuits. It delivers a displacement of 71 cm³ per revolution so users can size output precisely for medium-duty actuators. At 1450 rpm the unit provides a maximum flow of 104 L/min, supporting rapid cylinder movement in production machinery. A drive power demand of 16.5 kW at maximum pressure helps engineers evaluate motor sizing. The pump withstands operating pressures up to 80 bar, suiting low to mid-pressure hydraulic lines. Rotation is clockwise when viewed on the shaft, ensuring correct coupling orientation with standard industrial prime movers. The D0 remote pressure-adjustment controller allows pressure set-point changes from a separate control valve, simplifying circuit tuning. HLP mineral oil conforming to DIN 51524-2 is the specified hydraulic fluid, and a weight of 30 kg guides mounting provisions on machine frames.

For reliable suction the pump requires an absolute inlet pressure of at least 0.8 bar, while the outlet circuit must maintain 20 bar minimum to keep the vane set stable during low-flow conditions. Leakage at zero stroke is limited to 4 L/min at maximum pressure; this figure assists designers in calculating heat generation and tank sizing. The pump can start with oil viscosities up to 800 mm²/s, broadening cold-start capability in unheated plants. System cleanliness has to reach ISO 4406 class 20/18/15 so that wear on the sliding vanes remains low over long service intervals. A pipe thread to ISO 228-1 is used on the pressure port, facilitating straightforward connection with common metric fittings, while the suction side employs a 1-1/2-inch flange according to ISO 6162-1 to allow rigid low-restriction intake lines. Together these limits and connection features enable predictable operation when the pump is integrated into automated hydraulic systems.
