KNF, a manufacturer of diaphragm pumps and systems for gases, vapours and liquids, has launched a new low-pulsation liquid diaphragm pump, the FP 150.
The new product expands the company’s line of next-generation low pulsation liquid diaphragm pumps which combines the pulsation level previously only achieved by gear pumps with the advantages of diaphragm pump technology.
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 new 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.
The full KNF line of low-pulsation liquid pumps are designed specifically to provide gentle, low-shear conveyance of sensitive media.
The FP 150 has already been intensively tested for at large printer, ink, and medical device manufacturers in the US, UK, Italy and Israel.
