QY Pump is a horizontal self-sunction gas-liquid mixing pump, which is connected with special motor directly. All the flow parts of the pump is made of stainless steel by precise molding technology. The suction inlet of the pump can suck gas by negative pressure, so it is not needed to use gas compressor of gas jet. The quickly rotating impeller mix the gas and liquid, so mixer is not needed. Because of the mxing by added pressure in the volute, gas and liquid dissolveds with each other completely.The dissolution efficiency arrives to 80-100%, so big added pressure gas tank or expensive reactor mixing tower is not needed to get high concentration solution. One gas-liquid mixing pump can suck, mix, dissolve gas an liquid. And pump the high concentration solution to the application place directly.Therefore, the usage of the pump can improve the making efficiency of gas-liquid solution, simplify making device, save space, decrease first investment cost, save operration and maintenance cost.
