KNF has introduced a new series of OEM liquid diaphragm pumps. The FM 50 is designed to offer high precision and reliability for demanding applications.

The FM 50 series enhances liquid metering accuracy and customization, utilizing advanced pump drive technology for easy system integration and durability. The pumps deliver a flow rate of 100-500 ml/min with a setpoint accuracy of +/- 2 % and maintain a linear flow rate even under varying conditions, with a back pressure of up to 1 bar.

The FM 50's motor allows for control via voltage or PWM signal, with standard settings providing 100 ml/min at 1 V or 20% PWM and 500 ml/min at 5 V or 100% PWM. The motor can be factory-parameterized to meet specific customer requirements, including a 2-point calibration for customized flow characteristics.

The FM 50's polypropylene head, combined with EPDM or PTFE diaphragms and EPDM or FFKM valves, ensures safe transfer of most liquids. The pump is leak-tight, self-priming, and run-dry safe, making it suitable for transferring and metering fluids in in medical devices, diagnostic and analytical instruments, inkjet technology, cleaning and disinfection, and food and beverage applications.
