How to select the suitable vacuum pump for molding machine? The rotary vane pump has a good and wide application in this process. The selection of the vacuum pump of the blister machine needs to select the appropriate vacuum pump according to the specific process. Generally, the following two par...

Molecular pumps may involve different installation methods during the use of the unit, so can all molecular pumps be installed at any angle? Our molecular pumps FB-300 (300L/s), FB-650 (650L/s), FB-1300 (1300L/s), FB-2000 (2000L/s) can be either air-cooling or water-cooling, even when they are wa...

The temperature of the operating fluid of the liquid ring vacuum pump should not exceed 40C in theory, and the suction medium should not exceed 70C. Then, what if the pumping medium of the pump is 90°C, can the liquid ring vacuum pump be used? What is the service life of 304 stainless steel impel...

Hard candy is the hardest kind of candy. It is boiled at high temperature and has a low water content. Its obvious characteristics are that it is brittle and mostly transparent and glass-like. Hard candies are divided into different categories according to different crafts, shapes, packaging, col...

The 2BE3-300 water ring vacuum pump produced by EVP company can replace the Siemens 2BE3-300 vacuum pump. For this model, our company can produce: conventional cast iron (see the table below for details), stainless steel 304 material, stainless steel 316 （or 316L）material, or even titanium or d...

Liquid ring pumps are available in single-stage and double-stage designs, and can also be configured as compressors, such as 2BE, and we also specialized in compressors such as SY/2SY，LRC for more versatility. A single set compressor can reach up to 7barG. The principle of Liquid ring compressor...

Ketene is an organic compound with a chemical formula of C2H2O. It is the simplest ketene. It is a toxic gas at room temperature and is very unstable. It can only be stored at low temperature. At 0 °C, a polymerization reaction can occur. Ketene is a colorless gas; it has a pungent odor similar t...

The vacuum degassing of molten steel is a key operation in secondary steel-making, which can quickly and effectively remove the dissolved impurity gases (mainly hydrogen and carbon monoxide) in the molten steel and reduce the dissolved carbon content in the molten steel, thereby improving the qua...

Many materials are often heat-sensitive, viscous and/or have high boiling point properties, such as heavy petroleum residues, chemicals, medicines and natural foods, health products, fatty acids, etc. If we want to separate and purify the components of these materials It is necessary to maintain ...
