1. What is a slurry pump?
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. They can also be applied Multi-staged in series.
2. What advantage of ZJ(R) slurry pump?
ZJ(R) slurry pumps are suitable for mining, chemical and industrial applications. 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.
3. What application of ZJ(R) slurry pump
ZJ(R) are designed for ultra heavy duty applications such as process plant and tailings, high pressure pipelines, as well as other specialty applications. SAG mill discharge, Ball mill discharge, Rod mill discharge, Ni acid slurry, Coarse sand, Coarse tailings, Phosphate matrix, Minerals concentrate, Heavy media, Dredging, Bottom/fly ash, lime grinding, Oil sands, Mineral sands, Fine tailings, Phosphoric acid, Coal, Flotation, Process chemical, Pulp and paper, FGD etc.
