KNF Neuberger UK Ltd
About us
KNF is the technology leader in diaphragm pumps. Our portfolio includes OEM, process and laboratory solutions for gas, liquid and vacuum applications used in the medical, inkjet, gas analysis, food and chemical industries, as well as a wide range of other sectors.
KNF OEM and process pumps transfer gases and liquids or create vacuum. Thanks to a modular system, all KNF pumps can be customized quickly, easily and reliably to meet individual requirements—even from batch size one. Across industries, these pumps are valued for their leak tightness, clean operation, chemical compatibility, gentle media handling and outstanding reliability.
NEW: High Precision Dosing & Metering Pumps
KNF has expanded its liquid handling portfolio with two major additions designed to deliver next-level accuracy, control and system integration:
New FMS Family – Integrated Ultrasonic Flow Measurement
The new FMS pump family features integrated ultrasonic flow sensing, enabling true closed loop feedback for highly stable and repeatable flow control. This built in measurement capability ensures reliable fluid metering and continuous monitoring without external sensors, offering significant advantages for applications requiring accuracy, traceability and automation.
New FD 1.200 – Bidirectional Precision Dosing
The new FD 1.200 dosing pump provides exceptional precision with the ability to dose fluids accurately in both directions. This bidirectional functionality enhances system flexibility, reduces the need for additional valves or components, and supports applications where exact fluid control, reversibility and tight tolerances are critical.
Together, these new technologies further strengthen KNF’s position as a global leader in reliable, high precision liquid handling solutions.
