Polyurethane Slurry Pump Main parts\r\nPolyurethane Slurry Pump Impeller\r\nPolyurethane Slurry Pump Liners\r\nPolyurethane Slurry Pump Throat Bush\r\n\r\n\r\nDesign Features of Slurry Pump Polyurethane Liners\r\nSlurry pump polyurethane impeller and liner have excellent resistance to wear and have an average life of 3 times compared to rubber and metal impeller and liner. Polyurethane pump parts (Polyurethane Slurry Pump Parts) have longer life, lower frequency and more useful life than similar samples.\r\n\r\nPolyurethane pump liners and impellers have excellent resistance to hydrolysis, oily substances, that\'s why it is used in mineral processing lines and transportation of chemical and petroleum materials.\r\n\r\nIn Karhamani Polyurethane Industries, PU Pump Liners are designed and produced with a special casting method and special raw materials with different surface hardness, and the polyurethane pump parts have a metal core that is bonded with a very strong special adhesive. and creates a uniform and continuous.\r\n\r\nPolyurethane propeller (PU Pump Impeller) and alternative polyurethane liner have a smooth surface, no bubbles, no sticky materials on the surface, and low friction coefficient have high efficiency in transferring materials.\r\n\r\nDue to its excellent rebound performance and impact resistance, the polyurethane parts of the pump reduce the shocks to the pump and prevent the pump from breaking down, and it has a function without noise pollution.\r\n\r\nPolyurethane propeller and liner have very good radiation resistance and have shown good performance in radiation dose of 10-10Gy.\r\n\r\nPolyurethane pump impeller\r\nSlurry pump impeller\r\n\r\nThe advantage of polyurethane pump parts over rubber pump parts:\r\n5 times the life of polyurethane pump parts compared to rubber pump parts\r\n\r\nSmoother surface of polyurethane propeller\r\n\r\nThe ability to produce polyurethane parts with different surface hardness\r\n\r\nResistance to acidic and alkaline environments\r\n\r\nResistance to chemical environments\r\n\r\nResistance to all kinds of solvents and oils\r\n\r\nResistance to temperature changes\r\n\r\nIt has better elastic and elongation properties than rubber\r\n\r\nThe tear resistance of polyurethane is twice that of rubber\r\n\r\nWear resistance 3 to 5 times of polyurethane compared to rubber\r\n\r\nReduce maintenance cost\r\n\r\nReduce pump sleep hours
