KNF Neuberger Inc. manufactures precision, oil-free diaphragm pumps for the original equipment manufacturer (OEM), the process industry, and for the laboratory. Located in a modern, 34,000 sq. ft. corporate headquarters and manufacturing facility near Trenton, NJ, KNF Inc. is a subsidiary of KNF Neuberger GmbH. R&D and manufacturing facilities are located around the world. KNF holds over 100 patents and has been applying solid engineering principles to pump design since 1949.
Multi-port valves and molded diaphragms - a KNF exclusive. KNF's latest models represent a significant advancement in diaphragm pump technology. Their patented, multi-port valve system tolerates occasional liquid condensate droplets without the risk of pump damage or loss of performance. The smooth-surfaced diaphragm fits close to the top of the chamber surface, maximizing vacuum performance. As a result, end vacuums up to 29.86" Hg (<0.5 mbar) are possible using only two stages, reducing cost, space, weight and power requirements. Brushless DC technology includes new, integrated driver features. Portable instrument designers need look no further for economical brushless DC models. KNF's latest design offers low current draw, long lifetime, and reduced EMI/RFI. A custom, integrated speed control (with feedback,) and current-limit control combine with a powerful, highly-efficient motor to provide the perfect pump for your design requirement.
KNF welcomes complete system integration
A pump is the heart of any instrument, though equipment designers are seldom familiar with construction details affecting performance and life. Nor are they familiar with the pump's relationship to other components in the system. They welcome the opportunity to provide more than just the pump to you. KNF frequently adds value by providing a "system" comprised of components such as fittings, tubing, filters, valves, gages, mounting connectors and other related fluidics and electrical items, allowing you to dedicate your limited resources to your core competencies. Innovative technology is also applied to KNF's liquid pumps. In addition to air and gas pumps, KNF offers high-performance, diaphragm-based liquid pumps. Their unique, modular design provides a choice of wetted materials, and offer a variety of features. KNF Neuberger, Inc. specializes in custom diaphragm vacuum pumps, liquid pumps and compressors for the OEM, lab and process industries.
Liquid OEM Pumps
Liquid Pump Design Versatility
KNF's long experience with liquid pump design enables us to "optimize" our standard pump line to fit your exact specifications.
KNF liquid pumps use quite different construction than our air/gas line. Unlike other brands that simply adopt an air/gas pump for use with liquids, KNF's modern Swiss research and development product center, equipped with the best instrumentation, is dedicated to developing only high performance liquid pumps. Likewise, KNF's air/gas pumps are developed in our other dedicated research and development product center, located in Munzingen, Germany.

Process Pumps and Compressors
Tough Industrial Process Pumps
KNF pumps provide rugged, durable performance in a wide variety of industrial applications. For over 50 years, these heavy-duty pumps excel while handling even the most difficult corrosive applications. All KNF pumps are completely oil-free, and offer contamination-free operation.
We offer several categories of pumps for the industrial market:
• Heated-head and heat-resistant pumps for exhaust emission and stack-gas sampling
• Pumps for use in ATEX and Class I, Div I, Groups C and D explosive atmospheres
• Double diaphragm pumps to safely handle rare or dangerous gases
• High flow, corrosion-resistant sampling pumps for the chemical industry
• Leak-tight specific pumps for use with sensitive combustion analyzers.
We have design solutions for pumping air, gases and liquids, with models capable of handling neutral to highly-corrosive or difficult materials. Because of our extensive experience with many materials of construction, motor types, and modifications, we can easily build a pump that will fit your specific needs and perhaps save you money. Chances are, we've already built a pump for a similar application.
