High Quality Large Flow Anti-Abrasion Pump

Marine pumps can be replaced with wear-resistant metal or rubber gaskets and impellers, with long service life. The clearance between the impeller and the front bushing is easy to adjust and can be completely disassembled during maintenance. The bearing assemblies are lubricated with grease. V-belt drive, gear reducer drive, hydraulic coupling drive, variable frequency drive.

The pump body of twin-screw pump has several different heating structure options to adapt to different media and different temperatures.Gravel Sand pump (dredge pump) is designed as single casing connected by means of clamp bands and wide wet-passage.

When the pump is working, the engaging screw forms a seal chamber in the pump body. With the rotation of the screw, the liquid in the seal chamber moves axially with the seal chamber and is stably and continuously transmitted to the pump outlet. Since the capacity of sealing civilization has never changed in the working pump, there will be no pulsation when the pump delivers liquid.

The pump body adopts a round valve with special structure, which is opened when the outlet pressure is higher than the working pressure. Then, some medium will return to the inlet of the pump or storage tank through this annular valve. At the same time, the pump can be started under full pressure, thus greatly reducing torque.

The special design shall be adopted for the import and export civilization to ensure that there is enough medium left in the pump. Even if all the medium in the suction pipe is discharged, the pump still has good self-priming performance.
