The Busch Huckepack Mark 4 vacuum pump is a two-stage, Once-Through-Sealing, rotary vane design. The Mark 4 design allows engineers the flexibility and performance they need for their particular process including the choice of several sealing fluids with different vapor pressures.
Due to its high water vapor tolerance, the pump is ideal for handling solvents and condensable gases. This pump is considered environmentally safe as the cooling water is never in contact with the pumped gas. Therefore no waste water contamination occurs.
The Mark 4 is available in water-cooled (single pass) or radiator-cooled (closed loop) versions. It reaches an end vacuum of 0.5 torr (29.9" Hg), and comes in four sizes, from 113 CFM to 444 CFM.
