The twin-screw pumps are divided into two main categories, i.e., single-entry twin-screw pump and double-entry twin-screw pump. With special screw profile and the relevant special structure for them, they are widely used in oil, chemical, metallurgy, steel, electric power, marine, pharmaceutical, food, building materials industry, etc. A wide range of medium, transmission and complex operation conditions are allowable, with unsurpassed superiority to other pumps. With such advantages, this product series can have great application and development prospects.
Main features of 2G series single-entry twin-screw pumps: Bush supporting screw pair, little wear due to the indirect contact with the bushing; 2.
