KNF’s pump features for dosing

KNF has developed four new intelligent liquid, gas and vacuum pumps with integrated sensor technology, which offer advanced closed-loop control for achieving and maintaining flow, pressure or vacuum as well as precise dosages. The diaphragm pump features are for flow, pressure and vacuum control as well as versatile dosing.

For liquid metering applications, KNF has developed the FMS-FC 1.400. This diaphragm pump with integrated flow control uses a precise flow sensor and to ensure 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.

Another liquid diaphragm pump innovation is the FD 1.200 with versatile dosing, which delivers precise and repeatable volumes for demanding applications. For this, it uses 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..

The new MGP 75 diaphragm gas pump with intelligent pressure control maintains precise and consistent gas pressure even under changing conditions. Using 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.).

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

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

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.
