  • Pump types:Gear pumps ,Vane pumps,Piston pumps

    2015-8-4 · Pump capacity is determined by vane throw, vane cross sectional area and speed of rotation. The difference in pressure between outlet and inlet ports creates a severe load on the vanes and a large side load on the rotor shaft which can lead to bearing failure. The pump in Figure 2.1Oa is consequently known as an unbalanced vane pump.
