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.

Liquids can be suctioned using either direct liquid transfer or vacuum over liquid methods. It is important to understand these differences when selecting the appropriate technique and pump solution. While liquid suction may seem like a simple task, choosing the right suction method can be challenging. One option is direct liquid transfer, where the medium is transferred directly using a liquid pump. In vacuum over liquid transfer, a vacuum is used to suction the liquid. Both methods have their advantages, but there are also limitations. Understanding these differences is crucial to meet the specific requirements of the application. If the focus is on liquid transfer rather than liquid suction, the lesser-known method of pressurized liquid transfer may serve as an alternative.

When there is a need to transfer liquids, two different approaches can be considered: direct liquid transfer and liquid transfer under pressure. What are the differences and potential limitations? When transferring liquids, engineers can choose to directly transfer fluids using liquid pumps. There is also a lesser-known method that utilizes the pressure difference created by a gas pump to indirectly transfer liquids. To select the best method for the application, it is important to understand the differences, advantages, and limitations of both transfer methods. If suction is required, the liquid vacuum method may be an option.

By equipping a safety diaphragm, we ensure leak-free and contamination-free pump operation that meets the highest safety standards, even in the unlikely event that the working diaphragm is damaged.

Pump cavitation occurs when localized low-pressure areas form within the pump or system, leading to the formation and collapse of bubbles. This can cause erosion, vibration, and noise, potentially resulting in significant damage to the pump body, other components of the fluid system, and the transported fluid. This phenomenon affects all positive displacement pumps, including diaphragm pumps, reciprocating pumps, centrifugal pumps, and gear pumps. Cavitation can be effectively prevented by adopting optimized pump solutions that incorporate built-in pulsation dampers and taking appropriate measures to optimize the entire fluid system.
