Oil sealed rotary vane vacuum pumps are being used in all areas of vacuum engineering. They are equally suited for both industrial production and research applications. They are best used to generate medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps. The double stage SOGEVAC NEO D rotary vane pumps excel also to their low noise levels and smooth operation. Many years of experience in vacuum engineering and the latest developments in pump technology combine in the SOGEVAC NEO D range the capability to adapt to the requirements of both the industry and the environment.

SOGEVAC NEO D pumps are are double stage oil sealed rotary vane pumps. Oil injected into the pump chamber for sealing, lubrication and cooling of the pump is recycled from the pump’s oil reservoir and filtered. The lubrication system is rated for continuous operation at high intake pressures (max. 1000 mbar abs.) so that the pumps may be used in a versatile manner from atmospheric down to ultimate pressure. The oil carried with the process gas is roughly separated in the oil box before the discharged gas enters the integrated exhaust filters where the fine oil mist is trapped. The thus filtered oil is collected in the oil box and then supplied back to the pump. 

The separating system optimized in consideration of all operating conditions for the vacuum pump guarantees – also at high intake pressures and when pumping out of vapors – an exhaust gas which is free of oil mist (separation efficiency over 99.9%). Materials used in the pump: Steel, Cast iron, Aluminium, FPM (FKM), Glass, Polyamid 6 6, Filter material (Polymers, Paper), Epoxy resin & Glass fibre. Pumps are yellow metal free.
