Many ZW125-120-20 structure type self-priming pump, which molten Italy SAER self-priming pumps, vacuum pumps, liquid pumps, metering pumps, gear pumps, corrosion resistant pumps, acid pumps, fire pumps direction of rotation flow. Then with the right backwater hole stream water confluence ZW65-30-18 pump, along the spiral flow. Because of the liquid in the volute continue to impact cascades ZW50-20-35 pump, constantly being crushed impeller, mixing it with a strong air pump, air-water mixture is generated, and continue to cause air and water flow can not be separated. The mixture was stripped in the volute exit the tongue, along the short tube into the separation chamber. Within a mixed-type self-priming at startup, to be opened before the bottom impeller return valve, so that the liquid flows back to the pump impeller inlet. Of water at high speed rotation of the impeller is mixed with the role of the air intake pipe to form a gas-water mixture is discharged to the separation chamber. Here the water and from the air exhaust recirculation valve returns to the impeller inlet. This is repeated until the air is drained, Sheung Shui to suck in the mixed type of pump, works with external mixing self-priming.
