In order meet requirments on development of the electric power,metallurgy and coal industries. Our works has designed and developed Series ZGD(P) .Up-to-date Generation Slurry Pump with large capacity,high head, multi- stages in series to remove ash&sludge and to deliver liquid-solids mixture,based on the experience of slurry pump design and manufacture for many years, and abstracting the research results of advanced technology from home and abroad. The main technical features of this pump are as follows; .CAD modern design, super hydraulic performannce,high efficiency and lower abrasion rate. .Wide passage, non-clogging and good performance of NPSH; Expeller seal combined with packing seal and mechnical seal havebe adopted to guaranteethe slurry from leakage; .Reliability design ensures long MTBF(mean time between events); The metric bearing with oil lubrication, reasonable lubricating and cooling systems ensure thebearing tobeoperated under thetemperature; .The materials of wet parts have thegood performance of anti-wearing and anticorrosion; .The pump can beused for seawater ash-removing to prevent it from the corrosion of sea water,salt and mist, and electochemica corrsion; .The pump can beoperated in series with muti-stage within permissible pressure. The series of pump has theadvantages of reasonable construction, high efficiency, reliable operation and easy maintenance. It can be widely used for handling themixture contained of abrasive and corrosive solids in electric power,metallurgy, mine, coal, constructional material and chemical industry departments, especial for removing ash and sludgein electric power station. The series ZGD(P) slurry pump is of horizontal, single-stage, single-suction, cantilever,double-casing, centrifugal slurry pump two kings of shaft seal- expeller seal combined with packing and mechanical seal havebeen used of series ZGD(P) slurry pump.
