Amostech® Slurry Pump Polyurethane Spare Parts directly contact with slurries, It is very crucial to the service life of slurry pumps. The worklife of Polyurethane parts is longer than Rubber materials for 3~5 times, Polyurethane wetted parts include Impeller,Throatbush, 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.

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.
• High wear resisting – Anti-resistant performance is from 0.01-0.10（cm3）/1.61km, Duration will be longer 3-5 times than rubber.
• High strength – Break strength and bearing capacity is higher than rubber.
• Oil resistance: As a kind of high molecular compound, it is almost incorruptible.
• Gadiation resistance: Polyurethane parts have high gadiation resistance, It still have good performance at 10-10Gy radiation dose.
• Good Vibration absorption
• Low temperature resistance
• High acid and alkali resistance

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.

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.
