Technology and features
Operating principle
Dry screw vacuum pumps convey the gas from the inlet to the outlet with two screw rotors that intermesh without contact. The pump chamber is oil-free; the pumps reach rough and medium vacuum in a single stage, are insensitive to water vapour and particles and are suitable for continuous operation.
The technology page shows the operating principle with an interactive drawing: Screw vacuum pumps.
Features of the series
- Clean-in-place and gas dilution module available for polymerisation and temperature-sensitive processes
- Cooling jacket on the housing as standard, shaft cooling for a lower operating temperature
- Wetted parts made of grey cast iron with Hastelloy C coating; other coatings and duplex stainless steel as an option
- Precisely manufactured for low vibration and a low risk of seizure
- Screws with variable pitch and optimised rotor profile: high efficiency and short evacuation times
- Specially designed mechanical seal against oil leakage, PTFE lip seal as an option
Manufacturer's data as given in the product descriptions of the individual models.
