KNF has introduced its next-generation diaphragm pump, the FP 400. The product is designed for recirculation applications in a diverse set of markets.
The pump combines the traditional advantages of diaphragm pump technology with a pulsation level comparable to gear pumps.
Pulsations for the new FP is less than 150mbar. Levels below this are achievable depending on system tubing hardness, tubing inside diameter, and flow path length/configuration.
The pump delivers up to 5L/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 the 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 is well suited for recirculation application in a diverse set of market including: inkjet printing, medical device, semiconductor and fuel cells.
Pfeiffer Vacuum introduces the new Pascal 2021 HW, a two-stage rotary vane pump with the highest vapour capacity in its class.
