KNF Unveils FM 50 Series: Advancing Precision in Liquid Metering

KNF introduces the FM 50 series of OEM liquid diaphragm pumps, which are designed for high precision and reliability in demanding applications. This new product line addresses the increasing need for accuracy in liquid metering, a crucial requirement across various industries, including medical devices, diagnostics, and food processing. The FM 50 pumps enhance operational efficiency with advanced pump drive technology that facilitates seamless system integration while ensuring durability under various operational conditions. With flow rates ranging from 100 to 500 ml/min and a setpoint accuracy of +/- 2%, the FM 50 series is poised to meet the rigorous standards expected in today's industrial landscape.

The FM 50 pumps operate effectively even under fluctuating conditions, maintaining a linear flow rate with a maximum back pressure of 1 bar. This adaptability is vital for applications such as inkjet technology and cleaning systems, where precise liquid delivery is essential. The innovative motor technology allows control via voltage or PWM signals, providing flexibility in operation. Standard settings enable the pumps to achieve 100 ml/min at 1 V or 20% PWM and up to 500 ml/min at 5 V or 100% PWM. Furthermore, customers have the option to tailor the pump's performance to specific requirements, including a factory-parameterized two-point calibration, ensuring that each unit meets the unique demands of its application.

Constructed with a robust polypropylene head and featuring EPDM or PTFE diaphragms and valves, the FM 50 series is designed to be leak-tight, self-priming, and safe for dry operation. These features enhance the pump's suitability for a broad range of uses, from medical and diagnostic instruments to food and beverage processing. KNF's commitment to innovation and quality is evident in this latest offering, reinforcing its position as a leader in diaphragm pump technology since its establishment in 1946. The FM 50 series not only exemplifies KNF's dedication to meeting diverse industrial needs but also sets a new standard for effective liquid metering solutions.

In addition to the FM 50 series, KNF continues to expand its comprehensive portfolio of diaphragm pumps, serving various sectors such as gas analysis and chemicals. The company’s emphasis on quality and performance ensures that it remains a trusted partner for OEM, process, and laboratory applications. As industries evolve and the demand for precision increases, KNF’s innovative solutions are positioned to deliver the reliability and accuracy needed in today’s competitive market.
