KNF Smooth Flow Promise

KNF
5-Diaphragm Technology
By interlacing the flow and the pulses generated by each of the 5 diaphragms, a very high and yet smooth flow is achieved in the diaphragm liquid pump. This helps to efficiently transfer liquids through long tubing with smaller diameters, since Smooth Flow Pumps reduce pressure loss. It also minimises vibration of the tubes which can cause a number of problems. (Featured product: KNF FP 150)
KNF
Wobbling Eccentric
At speeds of up to 4,000 rpm, the wobbling eccentric transforms rotational movement of the motor to linear motion needed to drive the diaphragms. All this with generating almost no vibration and noise, and with only minimal forces acting on the motor hardware. This ensures a long, maintenance-free and highly reliable performance of the diaphragm liquid pump in the customer’s system.
KNF
Integrated BLDC Motor
Supporting the wide flow controllability provided by the smooth flow of the 5 diaphragms, a brushless DC motor integrated in a tight IP65 alloy housing allows for precise adjustment of the flow rate between 0.2 to 1.5 l/min. The advantages of BLDC motors in Smooth Flow Pumps include nearly wear-free drives, a long service life and quiet operation with minimal vibration.
