SHZ-DIII water circulating vacuum pump series uses the circulating water as the working fluid, and uses the jet to produce negative pressure to spray.It provides vacuum conditions for evaporation, distillation, crystallization, drying, sublimation, decompression and filtration Main features of SHZ-DIII water circulating vacuum pump: 1. This machine adopts double-tap, can be used alone or in parallel, with two tables; 2. The host of stainless steel stamping, sophisticated appearance, the case is of special engineering plastics; 3. Silencer with a special fluid, reduce water, gas and liquid friction noise, so that higher and more stable vacuum. Corrosion-resistant, no pollution, low noise, easy to move, but also the user needs to install a vacuum valve, easy to operate; 4. Storage tanks using a newly developed special plastic material, containing acetone, ether, chloroform and other organic chemicals operations, with some corrosion resistant dissolution Application of SHZ-DIII water circulating vacuum pump SHZ-DIII water circulating vacuum pump could be used in various kinds of distillation and filtration experiments. It's an important and ideal device for lab and other chemical departments.
