KNF unveils FP 400 low pulsation diaphragm pump

KNF Neuberger (Trenton, N.J.) is touting its next-generation FP 400 low pulsation diaphragm pump, designed for recirculation applications in the medical device space and a host of other markets.

The FP 400 incorporates the traditional advantages of diaphragm pump technology such as self-priming, the ability to run dry, and a long, maintenance-free lifetime under continuous-operation conditions, but it also has a pulsation level comparable to gear pumps, according to KNF Neuberger.

KNF Neuberger explains more:

“Pulsation for new FP 400 is less than 150 mbar. Levels far below this are achievable, depending on system tubing hardness, tubing inside diameter, and flow path length/configuration. 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.”
