Cr27 Cr28 High Chrome Cast Iron Pump Parts Anti Wear For Dredge Pump

Sand Gravel Suction Dredging Pump Cr27 Cr28 Anti-Wear Hard Metal High Chrome Cast Iron Pump Parts


Product Description

The slurry pump parts consists wet parts, sealing parts, bearing assembly, pedestal and other parts.
In slurry pump, Wet Parts means the lining parts which contact with fluid media, usually it include impeller, volute, frame plate, throat bush. There parts will easily get corrosived or abrasived when working and get repalced every periods.
Usually the pump parts are made of iron, steel, bronze, brass, aluminum, plastic etc. For Slurry pumps they are normally made of High chrome alloy, elastomer, polyurethane, ceramic and some other customed. But High chrome alloy and elastomer are now the main material for the slurry pumps. Recent years some companies are trying to make wet parts by ceramics and many data come from labs and mills show that the ceramic wet parts can work for a longer time than high chrome alloy.
For chrome alloy material, the common type is High chrome Alloy(27%Cr), it can be used from Ph 5 to 12, and its hardness can be to HRC58, which is a very good choice for slurry control and transport. But in some conditions, the Ph may lower than 5, then we try A49, it can lower to Ph4, mostly used in FGD processing.
The elastomer are widely used in fine slurry conditions and lower Ph to 2. There are also many rubbers for different conditions, such as R08, R26, R55, S02, etc


Slurry Pump Main parts:
• Impeller - front and rear shrouds have pump out vanes that reduce recirculation and seal contamination.
Hard metal and molded rubber impellers are complete interchangeable. Cast in impeller threads require no
inserts or nuts. High efficiency and high head designs are also available.
• Liners - Easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of
maintenance. Hard metal liners are completely interchangeable with pressure molded elastomers. Elastomer
seal rings back all liner joints.
• Throat Bush - Wear is reduced and maintenance simplified by the use of tapered mating faces to allow
positive accurate alignment during assembly and simple removal.
• Bearing assembly - A large diameter shaft with short overhang minimizes deflection and contributes to long
bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
