Double-layer slurry pump
ZZ slurry pump is a research and development achievement for decades. In 2009, it won the China 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.There are various materials available for our slurry pump, including stainless steel SS304, SS316, SS316L, duplex stainless steel, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
