Water Circulating Vacuum Pump takes circulating water as working fluid to create negative pressure by fluid jet.
It can provide negative pressure condition for the processes of evaporation, distillation, crystallization, drying, sublimation, pressure-reducing filtration and so on, particularly be suitable for labs and small scale test of industries such as universities and colleges, scientific research institutes, chemical industry, pharmacy, biochemistry, foodstuff,  pesticide, agricultural engineering, biological engineering.

1. Equipped with two same sides.
2. It is an extension model of SHB-III. Features and materials are the same as that of SHB-III.
3. Four taps vacuumize at the same time and four gauges display independently. Four operators can do experiments at the same time, which reduces the laboratory cost.
4. It is convenient for the teacher to explain and demonstrate to students during teaching.
