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. Save water resources.
2. Save more than 35% of electricity than other types of vacuum pump.
3. Specialized fluid muffler can make the vacuum degree higher by reducing the gas in water and make it quieter by reducing the friction between gas and fluid.
4. Equipped with double-tap and double-gauge, it can be used alone or in parallel.
5. Resistant to acid, alkali and solvents.
6. High quality motor with fluorine rubber sealing which can avoid the invasion of corrosive gas.
7. Replace water regularly to keep water clean to ensure perfect vacuum condition.
8. Shorten the water replacing period when it is used to pump corrosive gas.
9. SHB-III: Shell, water tank, ejector, tee junction, check valve and suction nozzle are made of PP material. Pump body and impeller ( six flowing passages, dual sealing ) are made of SUS304.
10. SHB-IIIA: Ejector and suction nozzle are made of SUS304. Other components are the same as that of SHB-III.
11. SHB-IIIS: Pump body is made of PP material which is more suitable for acid gas. Other components are the same as that of SHB-III.
