Vane Pumps

Vane Pumps – Discharge Large Flow. Delivering rates from 1.5 to 75 GPM, Commonly Used in Industrial Situations with Pressure Ratings Ranging from 1000 to 2200 psi.

Vane pumps are positive-displacement units that generate a pumping action by causing vanes to track along a ring. The pumping mechanism of a vane pump consists of a rotor, vanes, ring and a port plate with kidney-shaped inlet and outlet ports.

The rotor of the vane pump houses the vanes and is driven by a shaft. The shaft is connected to a prime mover. As the rotor turns, vanes are thrown out by centrifugal force and track along the ring. As the vanes make contact with the ring, a positive seal is formed between the vane tip and ring. The rotor is positioned off-center to the ring,

Vane pumps are used in both stationary and mobile applications. Typical types of vane Pumps used are; Fixed Displacement Pumps – Single-stage pumps, Double Pumps, Combination Pumps – Two-stage pumps, and Variable Displacement Pumps.

There are two varying classifications; unbalanced or balanced. These classifications are based on the load placed on the bearings that support the rotating pumping mechanism.

The advantages of vane pumps are; less ripple in discharge pressure (particularly, the ripple does not need to be taken into account), efficiency decreases to a lesser extent even if the vane is worn out, small dimensions relative to the hydraulic power of the pump, and the ease of maintenance due to less failure.
