KNF UN726 FTP Diaphragm Vacuum Pump and Compressor


You’ll never have to worry about proper disposal of contaminated pump oil or aspirator contaminated water again!

KNF’s Solid-Teflon series of vacuum pumps are the perfect replacement for that oil-sealed vacuum pump or water aspirator you may be using. Using no costly water for its operation, it conserves valuable resources and helps protect the environment by eliminating disposal of solvent-contaminated waste water or pump oil.

The FT series eliminates the worry of chemical attack to your pump or contamination of your pumped medium. With heads of solid Teflon and a unique molded diaphragm tightly bonded to a thick layer of Teflon, these pumps will withstand most corrosive vapors found in the lab. They are UL listed, fitted with a handle, on-off switch and cord set for convenient bench-top laboratory use.




Consistent Performance: 

  • A KNF pump uses no water or air for its operation, and it always delivers consistent, dependable performance. Use it anywhere without worrying about house air, water or drain connections.

Smooth Diaphragm Surface: 

  • The diaphragm surface is smooth and continuous. The absence of a clamping disk eliminates a source of corrosion and leaks. The molded shape conforms tightly to the solid Teflon® pump head, reducing dead space in the pumping chamber and increasing end-vacuum performance.

Medium Transfer is Contamination-Free:

  • because our oil-free design eliminates backsteaming. Your pumped medium stays analytically pure.

Easy to Use and Maintain: 

  • Disassembly for occasional cleaning is quick and easy. Special tools or training are unnecessary. Heavy-duty ball-bearings are lubricated and sealed for life. Forget about dicarding spent pump oil or quantities of contaminated water.
