Advantages of crown tooth root design in melt gear pump

Batte melt pump, located in Zhengzhou, China, has been engaged in the design and manufacture of precision gear pumps since 2009. The products include melt metering pump, rubber extrusion pump, reactor kettle gear melt metering pump, etc. melt pump is widely used in the transportation, pressurization and metering of high-temperature and high viscosity polymers. The application fields of products include chemical fiber, extrusion, etc.

melt gear pump

The gear in the melt metering pump adopts the crown tooth root shape design, which reduces the shear energy and power consumption compared with the conventional standard tooth shape. In addition, the utilization of the tooth shape with low aspect ratio also reduces the distance that the polymer must pass through to discharge from the middle of the gear. These characteristics greatly reduce the energy transferred to the material, protect its mechanical properties, and maintain a low temperature throughout the process. At the same time, the service life of the melt metering pump is extended and the driving device is reduced, which provides an efficient and energy-saving stabilizing device for most extrusion systems. The coronal root tooth shape can effectively increase the output by 5-10%.

reactor kettle melt pump

The melt metering pump is driven by an independent motor, which can effectively block the upstream pressure fluctuation and flow fluctuation. The pressure pulsation at the outlet of the melt metering pump can be controlled within 1%. Using a melt metering pump in the extrusion production line can improve the flow output speed, reduce the shear and residence time of materials in the extruder, reduce the extrusion temperature and pressure pulsation, and improve productivity and product quality. info@battemachinery.com
