The following animation demonstrates how a rotary vane pump works.

Medical Vacuum Systems: Dry Vane


The principle types of positive-displacement pumps include: reciprocating and rocking piston, rotary vane, diaphragm, lobed rotor, and rotary screw designs.

The GVD 0.7-28 series of small oil-sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation.

Rotary Vane Vacuum Pump, Single And Two -

A rotary vane vacuum pump works by using centrifugal force to turn blades against the circular surface of a cylinder whereby pockets of air are pushed from an inlet port to an outlet port as air pressure increases.It SUCKS the air from the engine, thus reducing the air pressure build up created by blow due to combustion gases going past the piston rings into the pan.

I have had an interest in HVAC for a while and I wanted to look into these pumps to see what they were all about.

Vane pumps are noted for their dry priming, ease of maintenance, and good suction characteristics over the life of the pump.

This is why companies like Becker now supply dry vane systems to OEMS that bundle their pumps like the VTLF 250 with their machines to.

Different Types of Pumps & Their Working Methodology

This type of pump is a moderate cost means of achieving vacuum levels in the 98%.The oil-free unit is less expensive and would be easier to maintain.

This pump features cast aluminium housing that makes the pump lightweight whereas it adds to the durability of the pump with the thermally protected motor.

Sizing Vacuum Pumps -

It runs on a rated frequency and voltage of 60 Hz and 110V respectively.The closer you can get to 100% vacuum, the more air you can remove from your material.

The simplest vane pump consists of a circular rotor rotating inside of a larger circular cavity.

Each work differently and produce different levels of vacuum.In the RC 6, a chemistry-design diaphragm pump is used to back the rotary vane pump.
