Stable, reliable, and accurate flow in liquid diaphragm pumps When stable flow is important, KNF's Flow Control technology makes the operation of liquid pumps easy and reliable. The built-in sensors enable closed-loop control, allowing the diaphragm pump to automatically adjust motor speed to match the set values even under changing conditions. This includes external factors such as back pressure and fluid temperature changes, as well as internal factors like pump performance degradation at the end of the service cycle. The integrated flow sensor is optimized for the pump and directly transmits all data to the built-in pump control unit, achieving high setting accuracy. This makes it particularly suitable for applications where high precision is essential for measurement and dosing. This sensor employs ultrasonic flow meter technology to avoid contact with the fluid. This results in excellent leak prevention performance, enabling the transfer of almost any liquid, including corrosive, aggressive, and sensitive fluids.

Consistent, reliable, and precise vacuum conditions even under changing conditions. With KNF's intelligent pump function for Vacuum Control, achieving and maintaining precise vacuum levels has become easier than ever. Even when conditions fluctuate, the system automatically adjusts pump performance to maintain the set values. These compact yet powerful pumps offer exceptional efficiency, reliability, and durability. Our Vacuum Control intelligent function combines precise sensors, high-quality diaphragm pump technology, and advanced software into an integrated solution. This allows for the easy, reliable, and efficient achievement of the required vacuum state. By providing a comprehensive solution, KNF supports customers in reducing development time and optimizing system efficiency. Vacuum Control also offers an extremely compact closed-loop control solution that can be customized for individual applications while integrating all components.

Stable, high-reliability, and precise pressure levels in gas diaphragm pumps Maintaining stable pressure is essential in many gas processing processes. KNF's intelligent Pressure Control simplifies this task by automatically adjusting the motor speed of the diaphragm pump in response to real-time feedback from built-in sensors. This closed-loop system ensures that the set pressure is maintained even when external conditions such as back pressure or fluid temperature fluctuate, or when pump performance changes over time due to wear. Our MGP series intelligent gas pumps adopt cutting-edge modular design, enabling easy, flexible, and highly customized system integration. The robust aluminum housing is chemically and physically durable and features integrated grooves for easy installation of components like shock absorbers. The high-quality housing offers IP67 protection rating as needed. The dual-head configuration allows for heads to be installed in opposing (boxer-type) or adjacent (tandem-type) arrangements. Depending on performance requirements, heads can be connected in parallel or in series.

Automated systems use robotic arms for pick-and-place tasks. These robots rely on high-performance vacuum pumps in vacuum grippers to achieve high-speed and precise movements. Manufacturers, intralogistics, and warehouse operators around the world are facing a labor shortage. This has increased the need for automated systems using industrial robots. These robotic arms are used for repetitive and monotonous pick-and-place tasks in dynamic environments, requiring precise movements. The vacuum pumps mounted on the robots' vacuum grippers provide the necessary suction accuracy.

The pump tubing in a delivery system can have a significant impact on the performance of the pump. When connecting a liquid diaphragm pump to a system, engineers face numerous material choices for both the suction and discharge pump lines. Selecting the appropriate material is often more complex than it may initially seem. Therefore, it is extremely important to understand the most significant positive and negative impacts that the pump piping materials can have, as well as to know how to avoid or leverage those impacts.

Martin Becker, who has been with KNF for over 40 years and has achieved success as CEO for 26 of those years, has passed the CEO position to Alexander Heitzler, who has been with KNF since 2009 and has served as COO since 2021. Martin Becker will now focus on his role as Chairman of the Board. This decision marks his complete withdrawal from operational duties and brings an end to a carefully planned transition period. This change in management reflects KNF's long-term stability and its identity as a family-owned business.
