Vacuum pumps
Sort by:
Vacuum pumps in special design made of AISI 304 AISI 316.
Vacuum pumps are subdivided into ultra-high-vacuum, high-vacuum, medium-vacuum and low-vacuum pumps, depending on the principle of operation, into mechanical and physicochemical.
- Classification of pumps by design feature:
- Reciprocating;
- Diaphragm;
- Liquid ring, lamellar-rotary;
- Screw;
- Roots;
- Spool;
- Spiral;
- Ferry oil;
- Sorption;
- Cryogenic.
To obtain varying degrees of vacuum, appropriate pumps or a combination of them are required. The choice of the pump is determined by the type and amount of gases passed by the pump, and the range of operating pressures of the pump, and its parameters. There is no pump that can provide a vacuum over the entire pressure range with acceptable efficiency.
