KNF FP 150
High Performance with Low Pulsation

Thanks to its robust five-diaphragm design, KNF FP 150 is an excellent liquid pump that delivers a flow rate of up to 1.3 l/min with impressively low pulsation levels.

Depending on the speed and configuration, the values of the pump outflow can be less than 150 mbar at the nominal flow rate, making this pump ideal for transferring shear-sensitive media.

Adjustable and Customizable

Digitally-adjustable flow rates, outstanding linearity, and back pressure resistance of up to 2 bar are the most prominent pump characteristics of the FP 150.

In addition, the modularity of the design efficiently enables timely response to the market while offering numerous customization options. An NSF-certified version is also available. Contact us to learn more.
