Hot melt gear pumps are mainly used for pressurization and stable flow transportation of extruders or medium to high viscosity polymers, such as sheet, sheet, pipe, film, cable, co extrusion, mixing, precision extrusion, and other industries. It can also be installed in the melt pipeline as a booster pump; The heating method is mainly electric heating, suitable for processes such as PS PP PET PA ABS PE-LLD.
extrusion melt pump
The main characteristics of the hot melt gear pump are:
1. It can be applied to high temperature (350 ℃), high pressure (35MPa), high viscosity (20000Pa • s) working conditions;
2. Optimized channel design to avoid dead corners within the channel, reduce material residue, and improve product quality.
3. Improved gear parameter design ensures more stable output pressure and lower pulsation rate, making it suitable for precision extrusion.
4. Adopting high-temperature alloy steel, it has good wear resistance and long service life
5. Adopting different sealing methods, suitable for a wide range of viscosity.
6. Suitable installation methods can be provided according to different on-site situations of customers, making them more flexible and practical.

The melt booster pump is generally installed in the melt pipeline and used as a booster pump or metering pump. It is driven by a motor, reducer, and universal coupling. The extrusion melt pump is a positive displacement forced delivery pump, and the pump output flow can be adjusted by adjusting the pump speed. It is recommended to use a frequency conversion speed control method to achieve near linear flow output of the gear pump.
