A 5-ton dual-impeller pump vacuum unit, utilizing a water-jet vacuum pump as the vacuum generation element, and integrating power source, circulating water tank, vacuum measurement, and vacuum control components into a single vacuum system. This model is capable of extracting corrosive gases at temperatures up to 150°C and can be used in series with steam-jet pumps, offering high vacuum levels. It is widely applied in industries such as chemicals, textiles, food, brewing, metallurgy, and environmental protection, primarily for processes like vacuum absorption, vacuum filtration, vacuum concentration, vacuum drying, vacuum conveying, vacuum deoxygenation, and vacuum aeration. It is an ideal replacement for SZ-type water ring pumps and W-type reciprocating vacuum pumps.

Performance parameters of a 5-ton dual pump:

1. Performance values listed in the table are at a gas temperature of 20°C, atmospheric pressure of 1013.25 hPa (equivalent to 760 mmHg), relative humidity of 70%, and water circulation supply temperature of 15°C.

2. Suction rate tolerance ±10%.

3. The vacuum degree values in the table refer to the pressure below atmospheric pressure. (1mmHg = 1Torr = 133.3Pa; 0.1Mpa = 750mmHg).
