Learn About The Characteristics Of Hydraulic Vane Pumps

Vane pumps will operate efficiently on low-viscosity fluids such as ammonia, solvents, alcohol, fuel oil, gasoline, and refrigerants. The absence of metal-to-metal contact inside these pumps will eliminate the associated wear. They have low noise, dry coating, easy maintenance and good suction characteristics. Vane pumps provide constant flow by maintaining high speeds up to 3000 rpm.

Working pressure does not exceed 180-210 bar. Some vane pumps with constant pressure or constant power can adjust the center of the vane body. Sliding vanes (left), flexible vanes, swing vanes, rolling vanes and external vanes are different types of vane pumps. Among them, external vane pumps can handle larger solids, while flexible vane pumps can handle smaller solids, but they have good vacuum. In a short period of time, the vane pump can run dry.

In unbalanced vane pumps, all pumping occurs on one side of the rotor and shaft. The unbalanced vane pump has a circular shell, and the balanced vane pump has an oval shell with different pumping areas on both sides of the rotor. Balanced vane pumps use a fixed displacement design, while unbalanced vane pumps use a fixed displacement and a variable displacement.
