ZJ(R) Single Stage Double Casing Slurry Pump
1. Centrifugal Slurry Pump
The centrifugal slurry pump utilises the centrifugal force generated by a rotating impeller to impart energy to the slurry in the same manner as clear liquid type centrifugal pumps. Slurry pumps need much wider and heavier impellers to accommodate the passage of large particles. They also be constructed in special materials to withstand the internal wear caused by the solids.
ZJ(R) slurry pumps are suitable for pumping slurry with hard particles and in high density in industrial sectors. Which with good impeller size and design, its ease of maintenance, the type of shaft seal to be used and the choice of the optimum materials withstand wear caused by the abrasive, erosive and often corrosive attack on the materials. They can also be applied Multi-staged in series.
ZJ(R) pumps are those of cantilever, horizontal and centrifugal ones, whose shafts can be sealed by packing seals or by centrifugal type seals. The positions of the pump outlet can be positioned at an interval of 45°according to different requirements,so eight different angles can be applied by rotation in installation.
