Polyurethane Pump Parts

Slurry Pump Polyurethane Parts are directly connection 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.
√ Radiation resistance: Polyurethane parts have high radiation resistance, It still have good performance at 10-10Gy radiation dose.
√ Good Vibration absorption
√ Low temperature resistance
√ High acid and alkali resistance
