KNF Neuberger introduces new low-pulsation liquid diaphragm pump

KNF Neuberger recently introduced its new FP 150 low-pulsation liquid diaphragm pump, which the Trenton, N.J.–based company touts as ideal for liquid recirculation in medical applications such as medical temperature management and aesthetic laser tip cooling.

The addition of the FP 150 further expands a line of next-generation low-pulsation liquid diaphram pumps that combine the pulsation level previously only achieved by gear pumps with advantages of diaphragm pump technology, according to KNF Neuberger. Diaphram pumps are self-priming, safe to run dry, and have a long service life.

Here how KNF described the FP 150:

“Pulsation at the nominal flow rate for the new, smaller FP 150 is less than 150 mbar directly at the pump outlet. Peak-to-peak pulsation levels far below this are achievable, depending on system materials, configuration, running speed, and other damping methods. 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.”

KNF says it designed its full line of low-pulsation liquid pumps to provide gentle, low-shear conveyance of sensitive media. The pumps also boast low vibration and noise, chemically resistant flow path material options for use with aggressive media, and appropriate IP protection ratings, according to the company.
