Liquid suction: direct liquid transfer and liquid overhead vacuum transfer
- Product news
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.

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 safety diaphragm pumps guarantee leak prevention in harsh environments.
- Product news
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.
