KNF Introduces FP 400 Low Pulsation Diaphragm Pump
Trenton, NJ, Monday, March 25th, 2019 – The FP 400 is a next-generation diaphragm pump from KNF. It combines the traditional advantages of diaphragm pump technology — self priming, the ability to run dry, and long, maintenance-free lifetime under continuous-operation conditions — with a pulsation level comparable to gear pumps.
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.
The many benefits of FP 400 make it particularly well suited for recirculation applications in a diverse set of markets, including:
- Inkjet Printing: UV, water-based, and solvent ink recirculation to prevent pigment precipitation; ink temperature management; and meniscus control. Glaze, varnish, and hot-melt recirculation. Major global printer and ink manufacturers have already tested the FP 400 intensively for 18 months, raising much interest.
- Medical Device: Temperature management, including aesthetic laser cooling systems.
- Temperature management/cooling, particularly in systems with sensors sensitive to pulsation.
- Fuel Cells: Fuel recirculation and membrane hydration.
