Black pump

1, SZ, SY, SF-type structure of black pumps for the back door, do not disassemble pipeline maintenance, import and export pump flange design by 1.6MPa pressure. The main parts from the pump casing, the former protection lining, impeller (three-blade or six leaves), after the protection lining, after the protection lining, after the pump cover, suspension, shaft, bearing cap before and after. 2, I pump in the import of products based on the improvement of the hydraulic model, increasing the pump capacity and distribution density of the liquid. The series of pump impeller is fully open and with no plug, sealing position without leakage, wide flow channel, through the ability, through the diameter 20-80mm, fiber length 100-400mm, medium concentration of 6% or less transport of various liquids medium, for a wide range of products than the old pump about 10-20% efficient. 3, sealing can be used, single mechanical seal, packing two sealed form, the user can request and use. 4, pump manufacturing material for cast iron, cast steel, ordinary stainless steel, duplex stainless steel of four, bearings Harbin Bearing Factory quality bearings. 5, pump impeller balancing check to ensure that the work balance impeller run. 6, pump motors are used on the national exemption product, Anhui JAC Electric Co., Ltd.. 7, pump over-current used in all parts of polishing to ensure the delivery of slurry type media quality, from the overall look nice.
