Roots Booster with Water Ring Pump Vacuum System



DESCRIPTION
Roots Rotary Piston Pump System is made up with the Roots Vacuum Pump and Rotary Piston Vacuum Pump in series connection. Rotary Piston Vacuum Pump is used as the pre-vacuum pump and the backing vacuum pump of the Roots Vacuum Pump, while the Roots Vacuum Pump is the main vacuum pump. The selection of displacement ratio, between the Roots Vacuum Pump and the Rotary Piston Vacuum Pump, is mainly referred to the vacuum value of the vacuum system under long term running; when working in low vacuum, it is advised to select small displacement ratio(2:1 to 4:1); If working in medium or high vacuum, the bigger displacement ratio(4:1to10:1)should be preferred.
Â
ADVANTAGE
1.High vacuum, high exhausting efficiency in medium or high vacuum, wide working range, obvious energy-saving results.
2. Integrated rack, compact structure, small required space.
3. High automation, simple operation, easy maintenance, safe, reliable and durable running.
4. To customize a special pump system as per the specific needs of the end user.
