KNF recently launched the latest edition to its smooth flow series low pulsation pumps. The new FP70 combines the low-pulsation capabilities of gear and centrifugal pumps with the advantages of diaphragm pumps. The result is a smooth, self-priming, low pulsation pump for gentle liquid handling.

The FP70 has been designed with integrated pulsation technology so there is no need for additional dampening equipment — saving both space and cost. In addition, KNF enables customers to choose motors with different performance classes based on specific system requirements. The pump can be equipped with standard DC motors or with a digitally customizable brushless DC (BLDC) motor for precise flow control and adjustment.

The FP70 is designed with patented four-point valves, which ensure reliable self-priming even at very low motor speeds. KNF uses chemically resistant materials in the FP70, enabling the pump to convey almost any type of liquid, including those with high corrosivity. The smooth, low pulsation flow prevents bubble formation and reduces flow resistance in tubes, thus increasing process reliability.

The FP70 smooth flow pump can be used in a wide range of applications including medical technology, inkjet, 3D printing and analytical instruments. In some medical applications, equipment is often in direct contact with the patient. In such applications, a smooth flow pump is crucial for the effective and comfortable treatment of the patient. With the FP70, fewer pulses are transmitted from the liquid to the tubing and thus to the patient, making the experience less stressful.

The FP70 achieves a flow of up to 850 ml/min and is designed for an operating pressure of up to 2 bar (29.4 PSIG). The new KNF FP70 low pulsation pump is a uniquely designed, high efficiency pump with a very small footprint. The FP70 can be customized with various motor and hydraulic connection options to meet the specific requirements of a broad range of applications.
