一、Features: 
1. Strong pumping capacity: the impeller and distributor are optimized to increase the suction and exhaust area
2. Efficient operation: gas is drawn and discharged evenly along the distribution plate; The vent equipped with flexible valve plate can automatically adjust the exhaust Angle to avoid over-compression or under-compression.
3. Anti-cavitation strength: equipped with anti-cavitation device, and the distributor also has corresponding cavitation holes.
4. Strong adaptability: when over current parts are sprayed with polymer coating or over current surface is sprayed with non-metallic material layer (our company's patent), it can meet very harsh anti-corrosion requirements; At the same time, its smooth surface can effectively reduce the sediment of the ash and slow down the scaling process.
