Slurry Pump impeller is one of the most important parts of centrifugal slurry pump. Depending on site application, slurry pump impeller selection can be crucial to pump performance. Slurry applications can be especially hard on the impeller of slurry pump because of their abrasive nature. In order for your process to operate efficiently and stand up to the test of time, you must choose the proper slurry pump impeller.
Tobee® offers three different types of slurry pump impellers: open, closed, and semi-closed. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency. To learn more about the specifics of each type of slurry pump impeller.
Slurry Pump Spare Parts namely the pump parts have direct connection with slurries, They are very crucial to the service life of slurry pumps. The wetted parts include impeller, liner, throatbush, frame plate liner insert, casing etc., These parts are very easily worn-out components because they work under longtime impact of abrasive and corrosive slurries in the high speed. For the long service life of pump parts, the material plays an important role here.
Standard Materials Description:
Metal:
• KmTBCr27(Ultralloys®) is a wear resistant white cast iron that offers excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of KmTBCr27 alloy is provided by the presence of hard carbides in the microstructure. KmTBCr27 Alloy is particularly suited to mild acidic duties where erosion resistance is required.
• KmTBCr28(Extralloys®) is martensitic white iron with moderate erosion resistance.It has the main elements of Chrome 28%, low Carbon with hardness of 430 in Brinell, KmTBCr28 is a corrosion resistant white iron suitable for low PH corrosion duties, where erosive wear is also a problem.
• KmTBCr35(Hyperalloys®) is a premium erosion/corrosion alloy, The main elements of Chrome is 35-45%, low Carbon with hardness of 450 in Brinell. KmTBCr35 Alloy is suitable for phosphoric acid duties, FGD duties, sulphuric acid , and other moderately corrosive applications.
Slurry Pump Main parts:
• 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.
• 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.
• Casing - Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
• Impeller - front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomer impellers are complete interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
• Throatbush - Wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
