KNF FP 1.150
Low-Pulse Smooth Flow

Based on its distinctive five-diaphragm structure, KNF FP 1.150 is the newest addition to the Smooth Flow series in 2022, combining the advantages of diaphragm pumps with pulsation levels traditionally seen in gear and centrifugal pumps. 

While specifically designed for use in deionized water systems, this pump is also an ideal solution for fuel cells, analytical instruments, ink-jet printers, medical devices, semiconductor equipment, etc. 

Customized Performance on Request

The FP 1.150 delivers a flow rate of up to 1.1 l/min, a suction height of 2.3 mWg, and a pressure head of 60 mWg. Moreover, these performance parameters can be custom-fit by a tailored pump head:
