Desulfurization slurry circulation pump
ZDT desulfurization pump is a specially developed product for desulfurization and denitration process of power plant. It is suitable to be used as limestone slurry pump, filtrate pump,gypsum slurry discharge pump, drainage pump... The hydraulic models of ZDT desulfurization pump is optimized designed by CFD, and its passage is designed under the theory of abrasion of slurry pump.The wetted parts material for ZDT desulfurization pump is an anti-abrasive and anti-corrosive material which was developed by Zigong Pump itself.There are various materials available for our desulfurization slurry circulation pump, including stainless steel SS304, SS316, SS316L, duplex stainless steel, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
