German Rexroth original stock PV7 series hydraulic vane pumps designed for industrial appliions requiring reliable performance and precise fluid power delivery.
What is the difference between the PV7-1X and PV7-2X subseries?
The PV7-1X is a fixed-displacement vane pump with a simple structure and stable flow output; the PV7-2X is a variable-displacement vane pump that can adjust displacement automatically according to system pressure or flow demand to achieve energy saving.
How to adjust the output flow of the PV7-2X variable-displacement pump?
The PV7-2X is equipped with a pressure compensation or flow compensation control mechanism; adjust the set value of the compensation valve through the adjusting screw on the pump body to change the output flow of the pump.
What causes the PV7 series pump to fail to build pressure?
Possible reasons include severe internal leakage of the pump, incorrect setting of the relief valve, blocked oil suction path, damaged control valve core of the variable-displacement pump, or insufficient oil in the tank.
Can the PV7 series pumps be used in series or parallel connection?
Yes, multiple PV7 pumps can be connected in series (to increase system pressure) or in parallel (to increase system flow) under the condition of matching the motor power and pipeline diameter; it is necessary to set separate check valves and pressure relief devices for each pump.
What maintenance work should be done regularly for the PV7 series pumps?
Regular maintenance includes checking the oil level and cleanliness of the hydraulic oil, cleaning the suction filter and return filter, inspecting the tightness of the shaft seal and pipeline joints, checking the vibration and noise of the pump, and replacing the hydraulic oil and filter elements according to the maintenance cycle.
