A vane pump is a positive-displacement pump that transfers liquid by the rotating and extending motion of vanes within an eccentric rotor. Widely applied in industrial, automotive, and hydraulic systems, it is known for high efficiency, low pulsation, and stable output, making it an ideal choice for medium to low-pressure hydraulic systems.

How to choose the right vane pump?

First, specific operating requirements must be considered. The pump's performance should match the system's operating parameters. Second, determine the compatibility of the fluid or gas being pumped by the machine in terms of viscosity, chemical composition, etc. The pump's efficiency or energy consumption should also be considered, as these directly affect operating costs. Furthermore, the pump must be able to withstand demanding operating conditions and continuous operation. Finally, you should follow the manufacturer's specifications or consult an expert for long-term performance expectations and maintenance necessities.

Why is a gas ballast used in vane pumps?

Vane pumps use a gas ballast to prevent vapor from condensing inside the pump during the pumping process. This helps maintain the pump's efficiency and service life, especially when dealing with vapors and corrosive gases.

How important is the gauge in a vane pump system?

A vacuum gauge is crucial in a vane pump system as it monitors pressure levels and ensures the pump operates within the required vacuum range. It helps maintain optimal performance and safety by providing real-time vacuum measurements.
