This paper will review the benefits of gear pumps as used within the rubber industry. The gear pump is a positive displacement device that "meters" or doses elastomers at a very consistent flow. The pump generates pressure at a higher efficiency versus the extruder or mixer thus relieving the extruder from pressure building. Commonly used in the thermoplastic industry for more than 20 years, "a new generation of pumps" has been developed specifically for the elastomer and rubber industry. Key benefits will be: reduced product temperature, consistent die pressure and increased throughputs. Recent successes have included pumps for EPDM and other rubbers for straining, profiles and wire and cable. Recent developments with the pumps allow them to be used as an integral part in many tire manufacturing processes.
