ZMJ Slurry Pump is horizontal, cantilever, double casing, single-stage and single-suction centrifugal slurry pump. By internationally advanced solid-liquid two phase flow theory, our company newly designed this series of anti-abrasion and corrosion resistant slurry pump based on the principle of minimum hydraulic loss and abrasion. The fact that geometry of pump wet parts come in line with flowing state of pumped medium contributes to the reduction of local and whole coursehydraulic loss due to vortex and flow impact. Consequently, the abrasion of wet parts can be mitigated. The pump series have following benefits: complete range of specifications and performance, novel structure, high efficiency and energy conservation, low vibration, reliable operation, long service life, easy installation and maintenance etc.
Design, manufacture and quality of this series conform to Standard JB/T8096 Centrifugal slurry pumps.
ZMJ Slurry Pump is widely apply to mines, metallurgy, power, coal, chemical engineering, building materials and flue gas desulphurization peripheral system etc., and are used for delivering slurry with abrasive particles or corrosive slurry.
