Slurry Pump PU Expeller Parts

Advantages of Polyurethane Elastomeric Material

    The expeller is an important part in the slurry pump sealing system. When it USES polyurethane material, it can greatly improve service life.

    The molecular structure of polyurethane elastomer contains macromolecule of carbamate repeat links. It is stepwise polymerized by isocyanate resin monomerand compound containing reactive hydrogen. It features lots of excellent performances for plenty of polar bond existing in its molecular structure and stable hydrogen bond existing among molecules, polyurethane elastomer has nice physical and mechanical properties, and it is acknowledged anti abrasive material and is known as [King of Anti Abrasive Materials". It is a high polymer material between plastics and rubber, which has physical dynamic performance similar to rubber, and it could also be machined and formed like plastic materials. Polyurethane elastomeric material has the following advantages:

    1. Adjustability range of performance is large. Various physical and mechanical performances could be transformed within certain limits by materials selection or formula adjusting so as to meet users` various requirements on products.

    2. Excellent wear resistance. Especially under working conditions with wet medium like water, oil etc. its wear resistance is usually several to dozens times better than common rubber materials.

    3. Machinability. Polyurethane elastomeric products could be machined such as lathing, milling and drilling etc. under a certain hardness range.

    4. Oil resistant, ozone resistant, ageing resistant, radiation resistant, low temperature resistant.

• 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 east of maintenance. Hard metal liners are completely interchangeable with pressure molded elastomer. 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 completely 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.

• One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.
