Due to its structure, twin-screw pumps can directly self suction without the need for specialized self-priming devices, and have the ability to suck up due to the relatively low axial flow velocity of the conveying shaft. There is independent lubrication in the gearbox, separated from the pump working chamber. The advantages of this structure broaden the scope of use of twin-screw pumps.
