KNF launches new intelligent pumps

KNF, a leader in diaphragm pumps, has introduced four new intelligent pumps for flow, pressure, and vacuum control as well as versatile dosing

For liquid metering applications, KNF has developed the FMS-FC 1.400 diaphragm pump with integrated flow control , which uses a precise flow sensor and ensures precise, accurate, and stable liquid delivery. It achieves a maximum flow rate of 3.4 l/min, a maximum pressure of 6 bar (rel.) and offers a maximum suction height of 3 mH2O.

The FD 1.200 with Versatile Dosing delivers precise and repeatable volumes for demanding applications, using advanced stepper motor technology and actively actuated valves. It offers a maximum flow rate of 40 ml/min, a maximum pressure of 6 bar (rel.), and a suction height of at least 4.5 mH₂O. Compact, chemically resistant, and customisable, it sets a new standard for accurate dosing.

The new MGP 75 diaphragm gas pump with intelligent pressure control maintains precise and consistent gas pressure even under changing conditions. Using the latest KNF motor technology, it achieves a maximum flow rate of 78 l/min, a maximum pressure of 1 bar (rel.), and a maximum vacuum down to 25 mbar (abs.).

The new micro vacuum pump NVC 830 maintains exact vacuum levels in demanding environmentsusing intelligent vacuum control This compact pump delivers a maximum flow rate of 4.7 l/min and a maximum vacuum down to 55 mbar (abs.).

Special features

Each pump integrates modern sensor technology and proprietary motor control to maintain exact setpoints, even under dynamic conditions like changing pressure or media temperature. The pumps can operate autonomously or can be controlled via analog signals such as control voltage. For use in complex systems, the pumps also support modern communication protocols like UART, enabling seamless integration into smart environments.

Based on a modular design, the pumps can be customised quickly and cost-effectively. Options include material selection, electrical and line connections, and digital settings such as output setpoint, ramp-up speed or maximum motor speed limits, depending on the pump. This flexibility makes the pumps an ideal choice for critical applications in industrial processes.
