The PV7-1X/40-45RE37MD0-16 pump belongs to the PV7 Adjustable Vane Pumps series and is built by Bosch Rexroth for variable flow control in automated hydraulic systems. It delivers a displacement of 45 cm³ per revolution so circuit designers can match stroke volume to actuator demand. Under 1450 rpm and 10 bar it provides a maximum flow of 66 l/min, supporting medium-size machinery loops. The pump withstands operating pressures up to 160 bar, enabling reliable service in moderately high-pressure circuits. A permissible speed ceiling of 1800 rpm accommodates standard electric motor drives without overspeed concerns. Installation is simplified by a 4-hole ISO 3019-2 mounting flange, and the pressure outlet uses a G1×18 threaded port for direct connection to common pipework. Clockwise rotation must be observed when coupling the drive, and zero-stroke leakage is limited to 6.5 l/min to minimize heat generation during standby modes.
In addition, the unit incorporates a remote pressure controller which modulates vane angle to maintain set line pressure without local adjustment. Drive sizing is aided by a maximum power requirement of 20.5 kW at 1450 rpm and a peak drive torque of 280 Nm, figures that define compatible motor ratings. Case drain pressure may reach up to 2 bar, so the return line must stay within this limit to protect shaft seals. The suction side accepts a SAE 1 1/2 in flange, providing low-restriction inlet flow, while fluid containment depends on NBR seals suited to standard petroleum oils. Overall mass is 30 kg, allowing one-person handling with appropriate lifting aids and supporting rigid mounting in compact power units.
