Hydraulic vane pump and hydraulic gear pump are commonly used hydraulic pumps in mechanical category of cooperative engineering equipment, so what is the difference between the two pumps in use? What do we have in common?

1. Both of them have continuous flow, and there are pulsations of flow and pressure.

2. Both of them belong to rotary positive displacement pumps and have certain self-suction capacity. However, they cannot be used and operated due to low self-suction.

3. The theoretical flow rate of both is determined by the size and rotation speed of the operating element and has nothing to do with the discharge pressure of the pump.

4. The rated discharge pressure of the pump body has nothing to do with the size and rotating speed of the operating elements. What affects the size is the sealing performance of the pump body and the bearing capacity of the components.

Understanding the similarities between vane pump and gear pump can enable us to focus on specific use in some aspects, even under certain specific conditions, it can completely replace it.

Of course, the substitution here does not mean that the two pumps can be banned from each other, but only that they can be temporarily used under certain specific circumstances.
