High Quality Sand Suction Dredge Pump for Mining & Construction
ZS series gravel pump is designed for continuously handing the most difficult higher abrasive slurries which contain big solids. The ZS gravel pump is casted as a single pump casing structure with smooth flow channel. The flow channel parts are made of hard nickel and high chrom wear resistant alloy. The outlet direction of horizontal gravel pump can be adjusted according to the requested direction.
This gravel pump is suitable for long distance delivery, delivering strong abrasive sand, sludge in metal melting, dredging and so on.
