Flow Control

ケーエヌエフ・ジャパン KNF JAPAN

Stable, reliable, and accurate flow in liquid diaphragm pumps When stable flow is important, KNF's Flow Control technology makes the operation of liquid pumps easy and reliable. The built-in sensors enable closed-loop control, allowing the diaphragm pump to automatically adjust motor speed to match the set values even under changing conditions. This includes external factors such as back pressure and fluid temperature changes, as well as internal factors like pump performance degradation at the end of the service cycle. The integrated flow sensor is optimized for the pump and directly transmits all data to the built-in pump control unit, achieving high setting accuracy. This makes it particularly suitable for applications where high precision is essential for measurement and dosing. This sensor employs ultrasonic flow meter technology to avoid contact with the fluid. This results in excellent leak prevention performance, enabling the transfer of almost any liquid, including corrosive, aggressive, and sensitive fluids.
