Vane Pumps

Many vane pumps have a box-shaped housing.

Eaton/Vickers Vane Pump Design

Vane pumps are a little like a Swiss watch: full of small, intricate parts wrapped up in a tidy package.

Cartridge

Despite the fragile appearance of the vane pump internal works, it is an excellent flow source for many applications.

With smooth rotating motions, it is quieter than most gear pumps and piston pumps, and produces very smooth flow (no noticable pulsations).

It has a higher volumetric efficiency rating than gear pumps, which makes it suitable for medium-high system pressures.

There are two main designs for vane pumps.

  • Balanced - Fixed displacement
  • Unbalanced - Fixed or variable displacement/pressure compensated

Pumping Action

Vane pumps have a rotor that spins inside a large circular or oval chamber called a cam ring.

Vane chambers increase in volume on the inlet side where they take in fluid, and decrease in volume on the discharge side which forces the fluid out of the pump.
