Melt Gear Pump
GMP melt gear pump is a precision positive displacement pump used primarily in the polymer and chemical industries for the reliable and gentle transfer, pressurization, and metering of high-viscosity, high-temperature melts.
Technical data
GMP melt gear pumps are essential in polymer processing for several reasons:
- Pressure Building: They generate high pressure more effectively and consistently than extruders alone, which is crucial for forcing high-viscosity melts through dies, filters, or pipelines.
- Flow Stabilization and Metering: The precise meshing of the gears provides a very stable, low-pulsation flow and excellent metering control, which helps minimize dimensional tolerances in the final product and improves overall quality.
- Stress Reduction: By providing consistent pressure, the gear pump relieves the extruder screw of this task, which can lead to energy savings and improved overall production efficiency.
- Gentle Handling: They are designed to transport sensitive, high-viscosity media gently, with specific designs to avoid material retention or overheating (scorching)
