Complete Description Of Various Configurations Of Negative Pressure Pumps

The pump unit inlet is equipped with a filter to facilitate users to prevent particles or dust from entering the equipment when installing the pipeline, which will affect the startup and use. The pump unit is equipped with a return line and a shut-off valve to facilitate the adjustment of system pressure.

Sanitary Negative Pressure Pump uses methanol as the working fluid. When used for the first time, inject the working fluid into the gas-liquid separator to the normal liquid level. When the water ring vacuum pump is started, the working fluid supply valve is opened.

The working fluid enters the water ring vacuum pump. The pumped gas is compressed by the water ring vacuum pump and enters the side gas-liquid separator together with the working fluid. The gas is discharged from the exhaust port at the top of the separator into the tail gas recovery condenser. The condensed gas enters the subsequent related pipelines, and the working fluid continues to circulate after being cooled by the condenser.
