Flue Gas Desulfurization Pump


Flue gas desulfurization pump is a single stage, single suction horizontal centrifugal pump, mainly used as the circulating pump for absorbent tower in FGD appliances. This series of horizontal desulfurization pump is with compact structure, saving much space. Our company has developed a variety of materials for the flue gas desulfurization pump.


1. The wet parts adopt advanced hydraulic model, with technology optimized by CFD Performance Analysis, to ensure reliability and high efficiency.
2. Adjusting bearing assembly can change impeller position inside the volute, keeping the pump unit in a high efficient operating speed.
3. Our horizontal desulfurization pump for flue gas is with back-disassemble structure, simple construction and ease of maintenance, without need of dismantle suction and discharge pipes.
4. Double-row tapered roller bearings are fitted on a pump end, roller bearings are fitted on a drive end. Bearings are oil lubricated, which can improve their working condition and prolong working life.
5. Mechanical seal is specially designed for cartridge mechanical seal which is used in FGD process with reliable operation.
6. Delin flue gas desulfurization pump features wide range capacity, high efficiency, better energy saving.

Material for Horizontal Desulfurization Pump

We developed a new kind of material for the flue gas desulfurization pump - duplex phase stainless white iron - which is especially suitable for FGD devices. With anti-abrasive property of duplex stainless steel and corrosion resistance of high chrome white iron, the material qualifies for FGD process.
1. Pump casing, pump cover and adaptor plate are bearing pressure parts which are made of ductile iron and lined with rubber.
2. Impeller, suction cover/front liner insert are made of duplex phase stainless white iron.
3. Front liner, back liner, back liner insert are made of natural rubber which has good anti-corrosive property, light weight and low cost.
