Product Details

Low rotation speed for longer service life
Vital parts corrosion resistant
Large oil reservoir dilutes contaminants

Suggested Applications

Freeze Dryer
Vacuum Oven

ChemStar belt-driven Vacuum Pump is designed to tolerate harsh chemical contamination. Vital pump parts are corrosion resistant. The large oil reservoir with PTFE surfaces dilutes contamination and the low pump rotational speed lessens friction to reduce operating temperature and chemical effects. PTFE surfaces, fluorcarbon gaskets and seals, Nitrogen purge to cool and degas oil. ChemStar system comes with Gold Oil, a synthetic lubricant designed to minimize effects of chemical contaminants.

¹⁾CHEMSTAR pump should not be operated continuously at pressures above 10 torr. Ultimate pressure measured with a trapped McCleod gauge.
