Non-lubricated liquids or multi-phase media containing micro-solid impurities, because the wear degree of the non-sealed pump is smaller than that of the sealed screw pump, and the service life is longer. This is the main reason why the unsealed twin-screw pump is getting more and more attention, and its production quantity and application range are increasing day by day.
Sealed twin-screw pump has only two screw, but it satisfies all sealing conditions. Its composition and characteristics are similar to those of three-screw pumps. It is suitable for transporting clean lubricating liquid without impurities and can be used in high pressure situations.
Double suction structure, so that the axial force on the screw can be balanced. The drive gear and the bearing of the supporting screw of the pump are located outside the pump chamber and belong to the external bearing type structure. It can be used to transport the medium with poor lubricity. If the medium with good non-corrosiveness and lubricity is transported, the built-in bearing type structure can be adopted. Its bearing and driving gear are both located in the pump chamber, which can reduce the number of shaft seals of the pump. Double suction twin screw pump, pump shell with cooling jacket, transmission gear box has a serpentine tube through the coolant, it can be used to transport high temperature media. Screw pumps can also be driven by magnetic couplings, which can completely eliminate leakage. It is suitable for transporting toxic, valuable or seriously polluted lubricating liquids.
