一、Features: 
1. Strong pumping capacity: the impeller and distributor are optimized to increase the suction and exhaust area
2. Efficient operation: The 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 or under-compression.
3. Anti-cavitation strength: equipped with anti-cavitation device and the distributor also has corresponding cavitation holes.
4. Strong adaptability: when overflow part is sprayed with high molecular coating or over-flowing surface sprayed with non-metallic material layer (the company's patent), it can meet the requirement of very demanding corrosion protection; At the same time, its smooth surface can effectively reduce the sediment of the ash and slow down the scaling process.
