This company has introduced four new models into its family of diaphragm pumps, with new features focused on flow, pressure and vacuum control, as well as versatile dosing. For liquid metering applications, the company has developed the FMS-FC 1.400. This diaphragm pump with integrated flow-control functionality uses a precise flow sensor and ensures precise, accurate and stable liquid delivery. It achieves a maximum flowrate of 3.4 L/min, a maximum pressure of 6 bars (rel.) and offers a maximum suction height of 3 mH2O. Another liquid diaphragm pump, the FD 1.200 with versatile dosing, delivers precise and repeatable volumes for demanding applications. For these tasks, it uses advanced stepper-motor technology and actively actuated valves. It offers a maximum flowrate of 40 mL/min, a maximum pressure of 6 bars (rel.), and a suction height of at least 4.5 mH₂O. Compact, chemically resistant, and customizable, it sets a new standard for accurate dosing. The new MGP 75 diaphragm gas pump with intelligent -ressure control maintains precise and consistent gas pressure even under changing conditions. Using the latest motor technology, it achieves a maximum flowrate of 78 L/min, a maximum pressure of 1 bar (rel.), and a maximum vacuum down to 25 mbar (abs.). Finally, equipped with the intelligent vacuum-control feature, the new micro-vacuum pump NVC 830 maintains exact vacuum levels in demanding environments. This compact pump delivers a maximum flowrate of 4.7 L/min and a maximum vacuum down to 55 mbar (abs.)

Each pump integrates modern 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. It makes the potentially difficult integration of external sensor and development of new control logic from scratch obsolete. 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 customized 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 industries including medical technology, analytical systems, and industrial processes. — KNF DAN GmbH, Hamburg, Germany
