KNF further expands its line of next-generation low pulsation liquid diaphragm pumps with the introduction of the new FP 150, which combines the pulsation level previously only achieved by gear pumps with advantages of diaphragm pump technology: self-priming, safe to run dry, and long service life. Pulsation at the nominal flow rate for the new, smaller FP 150 is less than 150 mbar directly at the pump outlet. The pump delivers up to 1.5 L/min of liquid at back pressure up to 29 psig (2 barg), with complete linear control of flow between ~10% and 100% of the nominal flow rate (0.2–1.5 L/min). Pump flow is fully stable with fluid viscosities ranging between 1 and 150 cSt. The pump can also handle viscosities up to 500 cSt with some flow rate reduction.
