ZJ series slurry pumps are horizontal, axial suction, single-stage, single suction and centrifugal slurry pumps. In terms of hydraulic design, structural design and flow passage component materials, this series of pumps integrate and innovate the advantages of similar products at home and abroad. It has the characteristics of high efficiency and energy saving, low vibration, low noise, reliable operation, long service life and convenient maintenance. The comprehensive performance of the pump ranks the leading level in China, and the efficiency indexes of most pumps rank the international advanced level. It is suitable for conveying abrasive slurry containing solid particles in power, metallurgy, coal, building materials and other industries. Such as hydraulic ash removal in thermal power plant, slurry transportation in metallurgical concentrator, coal slurry and heavy medium transportation in coal washing plant, etc. The maximum slurry weight concentration CW of the allowed solid-liquid mixture is: ash (slag) slurry and coal slurry 45%; Pulp and heavy medium 60%. Models include 450zj, 350zj, 300zj, 250zj, 200zj, 150zj, 100zj, 80zj, 65zj, 50zj and 40zj, which are suitable for flow of 4.5m ³/ h~6000 m ³/ h. There are more than 70 pump types operating under the working condition of lift 6m ~ 134m.
