Tobee® Slurry Pump Polyurethane Parts are directly connection with slurries, It is very crucial to the service life of slurry pumps. The work-life of Polyurethane parts is longer than Rubber materials for 3~5 times, Polyurethane wetted parts include Impeller, Throat-bush, Frame plate liner, Cover plate liner, Frame plate liner insert etc. They are very easily worn-out components because they work under longtime impact of abrasive and corrosive slurries. For the long service life of pump parts, Polyurethane material plays an important role here.
Polyurethane Slurry Pump Spares and Parts Design Features:
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.
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.
Tobee® Polyurethane Slurry Pump Wetted Parts China Features & advantages:
√ Wide range of hardness - With the high hardness, The Polyurethane parts still have the good elongation and elasticity, The hardness of Polyurethane parts is at Shore A10-D80.
