New KNF Diaphragm Liquid Pump FP 70

16 October 2021

With the FP 70, KNF has added another low pulsation pump to the smooth flow series. The new pump combines the low pulsation from gear and centrifugal pumps and the strengths known from diaphragm pumps. 

The KNF FP 70 is self-priming and can run dry, handles the liquid transfer gently and cleanly, and is chemically resistant. Thanks to the integration of pulsation dampening technology, there is no need for additional pulsation dampening elements and tubing when using the KNF FP 70. That means the pump can operate with particularly low pulsation even where space is limited. 

The system’s requirements also come first when selecting the motor: The smooth flow pump can be equipped with motors of different performance classes, and their parameters can be precisely customized. 

The low pulsation pump is fully equipped for a smooth flow.  

The KNF FP 70 achieves a flow of up to 850 ml/min. and is developed for an operation up to 2 bar (29.4 PSIG) pressure. Furthermore, the patented 4-point-valves ensure the reliable self-priming of the pump. Thus, no additional priming pump is required. 

The KNF FP 70 smooth flow pump can be used in a wide range of applications including medical technology, inkjet, 3D printing and analytical instruments.
