Duplex Phase Stainless White Iron Gypsum Slurry Pump By Volute Liner / Frame Plate

Duplex Phase Stainless White Iron Gypsum Slurry Pump By Volute Liner / Frame Plate

Features:

1. The distinct characteristic of our FGD engineering pump is double - casing and rubber lined

technology. Double - casing structure refers that the pump body is divided into outer pump shell and

inner lining. The former bears pressure and insulates slurry. The latter contact abrasive and corrosive

slurry. We only need to replace the worn out inner liner.

2. FGD engineering pump is mainly used to transport limestone and gypusm slurry. This requires the wet

part performance will not only in anti - abrasive but also in anti - corrosive. Therefore, the wet parts (

such as impeller , volute liner and frame plate insert, etc . ) adopt A49 combined with rubber material .

The engineering practice shows that the service life of components made by ours is triple or even

higher than the traditional Cr30A product or duplex stainless steel pump.

Material

1. Our company developed a kind of new material duples phase stainless white iron (A49) on FGD device

2. specially . The material has anti-corrosive property of duplex stainless steel and anti-abrasive property of high chrome white iron so that it has remarkable anti-abrasive and anti-corrosive property in FGD process

3. Pump casing ,pump cover and adaptor plate are bearing pressure parts which are made of ductile iron

Rubber lined pump :impeller ,suction cover/front liner insert are made of duplex phase stainless white

iron .

4. Front liner ,back liner ,back liner insert material is natural rubber which has good anti-corrosive

property with light weight ,low cost .

5. Material lined pump :impeller ,volute ,liner , throatbushing ,frame plate liner insert are made of duplex

stainless white iron ,suction cover is made of ductile iron with rubber stuck .

Application

Fuel gas Desulphurization Pump/FGD system Pump

TDT series axial inhalation single stage single suction centrifugal desulphurization pump can be widely

used to deliver limestone or gypsum grout for gas desulphurization systems of heat-engine plants,

aluminium manufacturers and oil refines. In the grout , the acceptable content of chlorine ion is

60000ppm ,and the acceptable Ph value is between 2.5-13 .
