2W. W-sealed twin-screw pump-Botou Zhuobo Machinery Factory

2W. The W-sealed twin-screw pump adopts a double suction structure, with both ends of the screw in the same pressure chamber, and the force on the shaft can be balanced by itself. The bearings at both ends are installed separately and lubricated with lubricating oil (grease). A pair of synchronous gears are used to drive the screw teeth between the two screws without contact, leaving a small gap. Impurities in the medium cannot directly wear the screw teeth. There are two ways: one is horizontal entry and horizontal exit; Two, enter horizontally and exit vertically. Users can make their own choices according to their needs.

2W. Scope of application of W-sealed twin-screw pump:

2W. The W-sealed twin-screw pump is suitable for conveying without being affected by the medium. The sealed positive displacement rotary pump forms sealed cavities in the pump body through the mutual meshing of the main and driven screws in the pump body, as well as the cooperation between the screws and the pump body holes. When the screws rotate, these sealed cavities continuously move forward, pushing the liquid in the sealed cavities to be discharged from the outlet. Medium temperature: ≤ 150 ℃, viscosity: 3-760mm2/s, pressure: 0.6-6.3mpa. Flow rate: 0.6-570m3/h.
