KNF Neuberger Inc specializes in corrosion-resistant air and gas pumps, and self-priming liquid pumps. A KNF liquid pump can run dry indefinitely without damage, and can pump gas/liquid slurrys. KNF precision metering pumps can transfer and meter using one pump. KNF manufactures a complete line of diaphragm pumps and compressors, includes dry laboratory vacuum pumps. KNF's vacuum pumps are very compact, with many pump models reaching 1.5 Torr (29.91 in. Hg) end vacuum using only two pumping stages. KNF's dry, maintenance-free vacuum pump is used in the laboratory as an oil-free vacuum source for rotary evaporators, gel dryers, distillation units, filtration devices, vacuum ovens, vacuum concentrators, and other lab appliances.
KNF's pumps are a perfect replacement for dirty, high-maintenance rotary vane pumps that require not only maintenance down time to change oil, but also eliminates the problem of the proper disposal of contaminated pump oil. In addition, users of outdated water aspirators will realize economic savings resulting from not using precious drinking water resources nor will they risk EPA violations caused by improper disposal of drain water contaminated with hazardous solvents. Water aspirator vacuum performance also varies with the temperature of the water. Steady, precise vacuum levels can be achieved by using our oil free pumps with a corrosion resistant vacuum controller. The KNF vacuum pump controller features Kalrez, PP and Viton wetted parts and five memory settings for the storage of individual vacuum level and hysteresis set points. All wetted parts are external to the module for easy cleaning. There are no metal parts in the gas stream. KNF has recently introduced a new pump for use with vacuum ovens, our self-drying model which purges accumulated condensate from the pump heads on a timed interval.
On the OEM pump side, KNF miniature pumps are specified worldwide for use in medical devices such as liposuction pumps for aspirators, as sampling pumps for environmental instruments and analytical instruments. KNF heated head sampling pumps are perfect for use with stack gas sampling systems and prevent the condensation of sample gas in the pump head. KNF explosion proof pumps are used throughout industry in sampling systems, process control systems, analyzers and gas transfer, and are available in full Teflon PTFE construction. KNF liquid pumps are a perfect replacement for many peristaltic pump applications, as they use no tubing, are not subject to changes in flow rate due to peristaltic tubing fatigue or tearing, and are available in all PTFE construction with no metal wetted parts. Because KNF pumps are oil-free, they feature contamination free transfer of air or gases and are an excellent replacement for piston pumps.
