There are several types of industrial high
vacuum pumps:
Diaphragm Pumps:
- Description: These are positive displacement pumps that use a diaphragm to move air or gas.
- Vacuum Level: They can achieve medium to rough vacuum levels.
- Applications: Often used for applications that require non-contaminated gases, such as vacuum filtration, degassing, and general laboratory use.
- Advantages: Low maintenance, oil-free operation, and quiet operation.
- Description: These pumps use rotating vanes inside a cylinder to move air or gas, creating a vacuum. They are typically oil-sealed, although oil-free models are available.
- Vacuum Level: Medium to high vacuum levels, depending on the design.
- Applications: Commonly used in general laboratory applications, including filtration, degassing, and distillation.
- Advantages: Reliable, robust, and can handle a wide range of substances.
