The independently developed intelligent KHF series digital metering pump provides customers with an intelligent solution for precise chemical dosing. The mechanical structure of the digital metering pump is simple, and it is convenient to install and maintain. Its unique drive design makes flow control simple and precise. The pump integrates multiple intelligent designs and controls aspects such as flow rate, liquid level, pressure and time. It performs automated calculations and feedback through an integrated microprocessor. The friendly button-based human-machine interface system makes operation more convenient.
