This product is of high efficiency, long life, light weight, reasonable structure 300ZJ-85 slurry pumps, reliable operation, easy maintenance 300ZJ-56 slurry pumps, for electric power, metallurgy, coal, building materials and other industries 300ZJ-70 slurry pumps, handling media for abrasive or corrosive slurry containing solid particles, the solid-liquid mixing mortar concentration of 45%, 60% pulp, medium temperature ≤60 ° C, the pump can use a multi-stage cascade. Seal type: EZJ series slurry can be used expeller seal combined with packing seal and mechanical seal two kinds of forms. (1) Vice impeller dynamic seals: Vice impeller seal using pressure impeller and expeller series produced seals, packing seals or lip seals as parking. The first stage pump slurry pump single stage or multi-stage pump when the pump inlet in series with the positive pressure pump outlet pressure is not greater than the value of 10%, can use this sealed form. It can be run without the seal of water, not diluted pulp, good sealing effect and other characteristics. But the increase (about 5% of the general need to increase shaft power) power consumption. Packing seal is a common form for a variety of working conditions, can be matched PTFE packing, graphite packing and other special materials can be used for corrosive or high temperature conditions. It has a simple structure and easy maintenance. 300ZJ-70 slurry pumps, Shijiazhuang-school Pump (certified), provided by the Shijiazhuang-Slurry Pump Co. faction. Shijiazhuang-faction Pump Co.
