Twin-screw pump is a constant volume sealed chamber formed between the screw sleeve and the pump body or bushing which engage each other on the main and follower axes. The medium is sent to the middle of the pump body with the rotation of the screw shaft, and the two are combined together to reach the outlet of the pump, thus realizing the purpose of pump transportation.


HW series double-suction twin-screw pumps are produced according to market requirements. They are driven by synchronous gears, the whole rolling machine is not in contact with each other, the bearing is external, the lubrication is broken, and they are not affected by the medium. Therefore, the transmission medium has a wide range and can transport various kinds of fluid media, including low viscous and high viscous, smooth and non-lubricating. The pump body is a double-layer structure and can pass through hot steam. It is a self-priming volumetric rotor pump, which is used to transport all kinds of fluid media without solid particles. It is widely used in petrochemical, metallurgical, electric power, shipbuilding, oil refining, machinery, papermaking, medicine, food and other fields. Each axle of the pump is equipped with a pair of spiral sleeves opposite to each other, and the driving shaft is driven by synchronous gears. The energy is transmitted to the driven shaft, so the spiral sleeves meshing with each other on the main and slave axles will not produce metal contact.
