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.

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. The very harsh environments in chemical and pharmaceutical processes, as well as the transfer of hazardous materials, toxic substances, and expensive fluids, impose high safety standards on the systems used. Safety diaphragm pumps achieve excellent leak prevention and airtightness by adopting an additional diaphragm as an extra layer of safety.

The other is a design that connects up to five diaphragms in parallel, operating each with a phase difference to smooth the flow. Both configurations minimize vibration and noise, enabling precise flow control through a built-in brushless DC motor.

With the development of the Gentle Flow Pump, KNF has minimized the pulsation of liquid diaphragm pump systems and set a new standard for diaphragm pump technology. In this interview, Daniel Kohli, the head of product development at KNF Flodos, the liquid pump product center, provides unique insights into the development process, technology, and key benefits for customers. He also discusses KNF's first pump equipped with intelligent features, which is the latest innovation project.

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.

Biogas is an important pillar for the energy industry in aiming for a sustainable future. Biogas produced from various organic materials such as corn stalks and liquid fertilizers is a carbon-neutral fuel since it does not use fossil fuels. However, this promising energy source also has technical challenges that require cutting-edge solutions. This involves several steps where pumps play a fundamental role, and KNF is pleased to provide the ideal technology. There are multiple challenges in the transport and compression of biogas. The raw biogas emitted from bioreactors is usually fully saturated with water and contains impurities and about 40% carbon dioxide (CO2). Furthermore, this gas is flammable and must not be released into the atmosphere as it is a potent greenhouse gas. Due to these characteristics, pumps that are highly airtight, do not affect the integrity of the medium, and can easily handle various chemicals and condensate are required.
