SLIDING VANE PUMP

DESCRIPTION AND FEATURES

The model TVP - vane pumps are a type of rotary positive displacement pump. A set of paddle-like vanes, mounted radially on a cylindrical rotor, create a number of compartments in which fluid can be trapped and transported through the system. The vanes maintain a close seal against the wall of the pumping chamber preventing fluid from leaking back across the pump. Vane pumps are particularly useful for pumping thin liquids at high pressures. The pumps give low pulsation, accurate flows and have hardened components to resist wear and extend pump life.

Standard, construction and application

STR designd the vane pumps are ideal for pumping low to medium viscosity liquids, including those with entrained gases, and can give an accurate, smooth, low pulsation output. With a varying feed pressure, a vane pump will continue to provide a constant flow. They are especially noted for their dry priming, ease of maintenance, and good suction characteristics over the lifetime of the pump. There is no internal metal-to-metal contact and the pumps self-compensate for wear through vane extension. The efficiency of a vane pump decreases with increasing fluid viscosity so they are not suitable for high viscosity liquids
