Description
Roots pumps are positive displacement pumps without internal compression. They are used as the first stage ahead of a backing pump where higher pumping speeds and lower pressures are needed.
Characteristics
- No internal compression
- A backing pump is mandatory
- Considerably higher pumping speeds
- Combinations for lower ultimate pressures
Choosing a solution
To propose a specific pump or system we need the operating parameters: the required vacuum level, pumping speed, gas composition and duty cycle. Our team will recommend a model, accessories and a maintenance plan, together with the manufacturer’s available technical documentation.
