Vane pumps work well with low-viscosity fluids and are used to pump water to moderate pressures in several specific applications as noted here. Summary. This article presented a brief discussion of vane pumps including the common types and how they work.
A vane pump compresses air to create a void where vacuum is created. Depending on the model, it will take anywhere from 45 seconds to 2 minutes to build up vacuum to start working. A rotary blower displaces air to create that vacuum, creating negative pressure in seconds, and the technician is ready to work.

The main working part of vane pump is the rotor with a number of sliding blades. When the rotor turns, because of the stator inner cavity contour line or the eccentric configuration of the rotor, the blade slides in the blade slot, resulting in the change of working volume, thus creating suction and drainage effect.
A vane pump (Fig. 4.7) has a series of vanes that slide back and forth in slots. There are springs in these slots that push the vanes out until the tip contacts the cam ring. (Some designs port pressurized fluid into the slots to force the vanes out.) A chamber is formed between adjacent vanes
Feb 06, 2021· Worker The vane pump is a device that works on the principle of positive displacement. Consisting of a series of vanes that are mounted to a rotor that provides circulation with the main cavity, the vane pump makes it possible to force liquid through a pipe or duct system at the rate desired by the operator.
Rotary vane pumps are typically what we pumpers carry and have serviced. They usually offer trouble-free operation. They last 10 to 20 years. They do require turbine oil and the draining of mufflers daily.

In a vane-type pump, a slotted rotor splined to a drive shaft rotates between closely fitted side plates that are inside of an elliptical- or circular-shaped ring. Polished, hardened vanes slide in and out of the rotor slots and follow the ring contour by centrifugal force.
A vane is called adjustable if during pump assembly it can be inserted, have its pitch angle adjusted and then be fixed in position. If the vane's pitch angle can be altered while the pump is running, then this vane is called a variable pitch vane (see Impeller blade pitch control).
