SWING PISTON COMPRESSORS AND VACUUM PUMPS FOR AIR

The Swing Piston Pumps from KNF are based on a simple principal: As it rises and falls the piston tilts first to one side, then the other. The compression forces act along the axis of the connecting rod, so that there is no component of force acting against the cylinder wall to cause wear. Thanks to the sealing lip on the piston...

Screw-type dry vacuum pump designed to handle process by-products: liquids, condensate and even small particles. Dry Screw - SDV. Screw-type dry vacuum pump ... Two-stage, air-cooled rotary piston pump recommended for applications where operating pressure is below 0.1 Torr (0.13 mbar). Rotary Piston - KD & KDH.

Vacuum pump - Wikipedia

The base pressure of a rubber- and plastic-sealed piston pump system is typically 1 to 50 kPa, while a scroll pump might reach 10 Pa (when new) and a rotary vane oil pump with a clean and empty metallic chamber can easily achieve 0.1 Pa. A positive displacement vacuum pump moves the same volume of gas with each...
