Rotary pumps, including rotary vane pumps and rotary vacuum pumps, are versatile tools suitable for a wide range of applications due to their unique features and capabilities.
5 Key Applications of Rotary Pumps
1. Handling High Viscosity Liquids
Rotary vane pumps are commonly used for pumping high viscosity liquids, particularly oil. They are often found in engine rooms, where they handle lube oil and fuel oil. These pumps operate at a rotating speed of about 1500 revolutions per minute. They use a radial, movable plug to generate a vacuum. The vacuum chamber is greased with oil, and a rough vacuum can be achieved with a double-stage pump.
2. Laboratory and General Use
Rotary vane vacuum pumps are frequently used in laboratories and other settings. They are reasonably priced and offer high-performance capabilities. These pumps are compact and ideal for use with solvents and watery samples that tend to boil quickly. They can remove vapors before they come in contact with the pump, making them suitable for handling such samples.
3. Creating Low-Pressure Regions
Rotary vacuum pumps are designed to create low-pressure regions through the rotation of their moving components against the pump housing. These pumps use self-lubricating or low-friction materials between the rotor and housing to prevent fluid leakage. The small clearances in the pump design also contribute to a more continuous flow compared to reciprocating types. However, rotary vacuum pumps are not suitable for handling fluids contaminated by abrasive media, as this can erode the small clearances.
4. Positive Displacement Pumps
Rotary vane pumps are a type of positive displacement pump that utilizes vanes mounted to a rotor on an off-center drive shaft. These vanes create chambers of varying sizes as the rotor rotates, allowing fluid to be drawn in and expelled. These pumps require oil to create a tight seal and lubricate their parts.
5. Oil-Less Variations
Oil-less rotary vane vacuum pumps are a variation of rotary vane pumps that offer unique benefits. These pumps feature sliding vanes in a rotor rotating within a cavity and do not require oil for operation. They are able to self-compensate for wear, maintaining peak performance for longer periods. Oil-less rotary vane pumps are suitable for medium or variable vacuum ranges and have lower maintenance requirements compared to other types of pumps.
