The rotary vane pump has found its use in a wide range of applications including priming; hold down applications, vacuum drying, medical uses, food processing, lasers and thermoforming. It is also useful when it comes to pumping of oil and other viscous fluids. Most people who use these types of pumps in engine rooms use them for handling lubrication oil. The pumps have tiny clearances between stationary and rotating parts, which minimize slippage from the discharge side to the sanction. They fact that they are designed to work at low speed ensures that they sustain good clearances. This means that operating at higher speeds can cause excessive wear, eventually decreasing their pumping capacity.
You will different types of rotary vane pumps in high pressure applications such as vehicle hydraulics like power steering, super charging and automatic transmission pumps. Mid pressure applications such as soft drink carbonators and coffee machines also use rotary pane pump machines. It is also not unique to find these pumps in low pressure applications like chemical vapour deposition and secondary air injection in auto exhaust control applications
The simplest rotary vane pump is built with a circular rotating motor, placed inside a large circular cavity. The vanes are slid into the motor to seal all the edges, in order to create chambers that offer the pumping action. Global Vac offers both standard and customized rotary vane pumps for all types of commercial and industrial applications
