RP 12C, RP 15C VARIO, RP 22C VARIO and RP 35C VARIO

The combination of an oil-free chemistry diaphragm pump with a Roots pump leads to a significant increase in pumping speed and improves ultimate vacuum by an order of magnitude. VACUUBRAND "RP" Roots pumping units feature a high specific corrosion resistance. The dry and oil-free compression and their good pumping speed, particularly in the pressure range between 0.2 and 50 mbar, allow the pumping of large amounts of vapors. VARIO^® Roots pumping units use automatic, gas-load-dependent adjustment of the speed of the Roots pump. This results in high performance even at high inlet pressures and prevents overheating of the pump.

 

Performance features

• low ultimate vacuum < 0.2 mbar
• very high pumping speed from 12 to 40 m³/h, maximum between 0.2 and 50 mbar
• measurably reduced backflow of oil due to oil-free pump chamber of Roots pump
• virtually oil-free vacuum compared to rotary vane pumps
• active pollution control: less pollution of environment, no regular discharge of contaminated waste oil
