SZ Series of Water Ring Vacuum Pumps and Compressors

Details

SZ series of water ring vacuum pumps and compressors:

SZ series of water ring vacuum pumps and compressors are used for sucking and compressing air or other uncorrosive, insoluble gass which do not contain solid particle, to obtain a certain vacuum or a pressure in sealed vessels. The sucked gas may contain a small amount of liquid. These pumps are widely used in mechanical, petrochemical, pharmaceutical, food, sugar and electronic industry.

Since the process of air compression is isothermal, there is rarely danger happened when we pump and compress explosive gas, which enable wide application.

SZB water ring vacuum pump:

SZB cantilever water ring vacuum pump are used for pumping and compressing air or other uncorrosive, insoluble gas which do not contain solid particle; the ultimate vacuum reach 85%, especially fit for water priming of large water pump set.

The current pumps in production: SZB-4, SZB-8. 4 and 8 indicates the suction capacity (L/s) when the mercury column is 520mm.
