Two-stage vacuum systems with booster

The two stage vacuum systems are designed for those customers who need to couple vane vacuum pumps to Roots pumps.

This solution allows to obtain a greater capacity with a higher maximum pressure (up to 7 x 10-3 mbar) in a relatively small space.

The technical features of the system can be customized according to customer needs. PVR can develop vacuum systems choosing among the different pump technologies of its production with ad hoc solutions.

The two stage vacuum systems can be supplied with electric control panel compliant with EC standards, inlet filters and process control options.

The systems with bypass valve (-BP) allow the Roots pump to start against atmospheric pressure.

The systems are also available in the version regulated by VFD (Variable Frequency Drive).

The following accessories are useful for installation and for controlling the operating parameters of the pump:

- External suction filter
- Condensate separators
- Inverter
- High performance lubricants
