The KNF LABOPORT® series of diaphragm vacuum pumps are perfectly suited for laboratory bench applications. 

KNF LABOPORT® Series Laboratory Vacuum Pumps

LABOPORT diaphragm lab vacuum pumps are oil-free, easy to use, and conveniently carried to wherever vacuum is needed. Manufactured in the USA with chemically-resistant components – LABOPORT vacuum pumps are built to last, delivering accurate, reliable performance year after year!

Quiet and compact, LABOPORT pumps feature solid PTFE heads, FFPM valves and PTFE-covered diaphragms for maximum corrosion resistance. LABOPORT pumps are available with flow rates as high as 110 L/min and end vacuum to 1.5Torr. Additionally, LABOPORT vacuum pumps are designed to tolerate occasional liquids drawn into the pump system without damage, making them ideal for a wide range of laboratory applications including: rotary evaporation, filtration, vacuum ovens, and more.

LABOPORT Mini pumps feature chemically-resistant PPS heads, FFPM valves and PTFE-covered diaphragms. They are ideal for aspiration, filtration and other applications that require moderate vacuum and flow levels.

In addition to the full line of LABOPORT vacuum pumps, KNF also offers our exclusive PowerDry® models for applications which require the handling of very wet gases. PowerDry pumps automatically inject a burst of ambient air into the pump heads, clearing any trapped liquids while maintaining a stable vacuum level. Benefits provided by PowerDry-enabled LABOPORT pumps include: increased effective suction speed and extended pump service life in wet gas application conditions.
