News about this product(12)

The diaphragm vacuum pump for vacuum grippers guarantees the absolute precision of the robotic arm.

  • Product news

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.

Liquid transfer: direct liquid transfer and liquid level pressure transfer

  • Product news

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.

Reasons why lung monitoring devices rely on KNF pumps.

  • Product news

KNF's compact and reliable diaphragm gas pump is an essential component of important lung monitoring devices. Monitoring a patient's lung function plays a very important role in many medical applications. Lung monitoring devices take small samples of the patient's breath and send them to a gas sensor via a pump. This analytical device measures the concentrations of CO2, O2, and other gases, ensuring safety during medical procedures, especially during anesthesia and sedation. The diaphragm pump is an indispensable part of the medical equipment that performs this analysis.
