In the maintenance of Vane Pumps , external leakage is a common failure phenomenon. If this happens, it will cause unnecessary waste of energy and damage to the hydraulic system. So what should be excluded to solve the leakage fault outside the vane pump?

How to eliminate leakage outside the vane pump:

1. Seals are aging, replace seals

2. Loose connection of inlet and outlet ports

3.Tighten pipe joints or flange screws

4.The sealing surface bumps or there is trachoma in the casing of the pump
