KNF Introduces Intelligent Pump Features for Flow, Pressure and Vacuum Control and Versatile Dosing
KNF announces the introduction of four innovative diaphragm pump features for Flow, Pressure, and Vacuum Control as well as Versatile Dosing. These solutions set a new benchmark for precision, reliability, and adaptability.
Four New Intelligent Pumps
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 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.
Another intelligent 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. Compact, chemically resistant, and customizable, 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.).
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.).
Intelligent Features for Maximum Precision 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.
Flexible Connectivity and Integration
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.
Customization for Demanding Applications
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.
