Vacuubrand Oil Free Fine Vacuum Generation: Roots Pumping Units RP / RP VARIO

The combination of VACUUBRAND diaphragm pumps with a high performance roots pump extends the scope of applications as regards ultimate vacuum and pumping speed essentially. VACUUBRAND roots pumping units RP feature a low ultimate vacuum in the range of 10^-1 mbar with high pumping speed ranging from 6 to 35 m³/h. The problem of the increasing amount of contaminated waste oil is drastically reduced, since there is no oil in the pump chamber for lubrication and sealing.

Application

Roots pumping units RP are advantageous in a growing number of applications where high pumping speed below 50 mbar is required and where environmental considerations are ruling out other methods. Typical applications include e.g. distillation, freeze drying or evaporation under reduced thermal load, oil free systems such as load lock systems, electron microscopes and mass spectrometers or as low contamination backing pump for turbomolecular pumps, cryopumps etc.

Advantages

	oil free chemistry diaphragm pump
	roots type booster: no oil in pump chamber for lubrication or sealing
	high pumping speed between 0.5 and 10 mbar
	specific corrosion resistance
	low ultimate vacuum: < 0.3 mbar
	oil free* vacuum by a combination of two oil free* vacuum pumps (*diaphragm pump absolutely oil free. Roots without oil in pump chamber for lubrication or sealing; gear units oil filled; rotary shaft seal)
	fine vacuum with less contamination
	active pollution control: less pollution of the environment, equipment for solvent recovery, no contaminated waste oil
