Polyurethane Slurry pump throat bush is one of slurry pump wet parts in AH slurry pump which directs slurries to slurry pump impeller, it is suction side liner which is connected with slurry pump cover plate. Polyurethane throat bush is common in bigger slurry pumps, because slurry pump polyurethane throat bush and slurry pump cover plate liner are normally in one solid piece in small slurry pumps. The design of slurry pump PU throat bush is based on cost effective in manufacturing and operation.
Polyurethane Slurry Pump Parts 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
