Double-layer slurry pump
ZZ slurry pump is a research and development achievement for decades. In 2009, it won the Zigong Science and Technology Progress Award. The efficient design of solid-liquid two-phase flow is optimized. There are a variety of seal types, transfer methods and anti-wear materials for different applications. Suitable for pumping corrosive or abrasive slurries containing solids such as concentrates, tailings, coal ash, cinders, slurries, sediments... they can work in series if required.
■Flow rate: Q=10~5000（m³/h）
■Total head: H=20~120 (m)
■S.g.: γ ≤1.5
■Pump diameter: 50～450mm
■Optimized solid and liquid hydraulic model design of high efficiency and energy-saving.
■Thickened wetted parts design to improve the anti-abrasive ability and prolong pump life.
■Heavy duty shaft design,with better performance in strength.
■Reasonable bearing configuration and fully lubricated design ensures the long time and continuous operation.
■Suitable to pump corrosive or abrasive slurries contains solids,the mixture density of solids and liquid can be up to 60%.
■Various sealing types to meet different requirements.
■According to the requirements of clients,it can work in series.
■Axial split bracket and double layer casing structure.
■Outer casing is vertical split structure; pump outlet is able to be set on 8 different direction at 45° interval.
■Horizontal installation of big loading capacity.
■The jacket and guard plate as the lining,pump casing and pump cover is the frame.
■Shaft sealings: dynamic seal, packing seal and mechanical seal.
■Transmission: Direct coupled, V-belt drive, variable frequency drive, hydraulic coupling.
Structure drawing is as below
■Material of flow passage components based on pumped medium: Cr26 wear-resistant material, or Cr30, CD4MCu wear-resistant and anti-corrosion material, and other general wear-resistant material.
■Material of pump casing, pump cover, bracket etc. supporting parts: gray cast iron
