The FP 400 is a next-generation diaphragm pump from KNF.

It combines the traditional advantages of diaphragm pump technology with a pulsation level comparable to gear pumps.

The pump delivers up to 5 L/min of liquid at back pressures to 15 psi, with complete linear control of flow between 10% and 100% of the nominal flow rate. Pump flow is fully stable with fluid viscosities ranging between 1 and 150 cSt. The pump handles viscosities up to 500 cSt with some flow rate reduction.

KNF designed the FP 400 specifically to provide gentle, low-shear conveyance of sensitive media. Other strengths of this innovative new pump include very low vibration, a noise level below 55 dBA, chemically resistant flow path material options for use with aggressive media, and an IP65 protection rating.

The FP 400 make it particularly well suited for recirculation applications, including:

  • Inkjet printing

  • Medical devices

  • Semiconductors

  • Fuel cells
