SHB Series Laboratory Mini Electric Vacuum Pump

These Zhengzhou Greatwall SHB series Water Ring Vacuum Pump using water as circulating fluid to creat negative pressure by ejecting, providing vacuum condition for the processes of evaporation, distillation, crystallization, drying, sublimation, reduced pressure filteration etc. They are particularly designed for labs and small scale tests in universities and colleges, scientific research institutes, chemical industry, pharmacy, biochemistry, foodstuff, pesticide, agricultural engineering and biological engineering.

1.Saving resources by recirculating water;

2.Saving more than 35% of electiciry than other types of vacuum pump;

3.Specially designed fluid muffler can improve vacuum degree by reducing the gas in water, keeping it quiet running by reducing the friction between gas and water;

4.Double-head, double-gauge, which can be used alone or in parallel;

5.Resistant to acid, alkali and solvents;

6.World famous brand motors, viton gasket sealing, avoiding invasion of corrosive gas;

7.Replacing the water in the reservoir regularly to keep the water clean and ensure perfect vacuum condition;

8.Replacing water more regularly when it is used to pumping corrosive gas

    SHB-III: Housing, reservoir, ejector, tee junction, check valve and suction nozzle are all made of PP material. The body of pump and impeller(six flowing passages, dual sealing) are made of stainelss steel 304.

    SHB-IIIS: The body of pump body is made of PP material, which is more suitable for acid gas, the rest parts are the same as SHB-III;

    SHB-IIIG: It is a new generation of water circulating vauum pump; ejector and suction nozzle are made of PTFE. Hose is made of FPM(Fluorine rubbe); better corrosion resistance and longer life-span;

    SHB-IV A: Both sides are exactly the same; it is an extansion model of SHB-III, properties and materials are the same as SHB-III; four heads pump at the same time and four gauge display independently. It is possible for four people to do experiments at the same time, which can help reducing laboratory cost. It is convenient for the teacher to explain and demonstrate to students during teaching.
