Plastic granulation extruder melt pump
Introduction to the melt pump of plastic granulation extruder:
Plastic granulation melt pumps are mainly used for pressurization and stable flow transportation of extruders or medium to high viscosity polymers, such as granulation, sheet materials, plates, pipes, films, cables, 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.
The main characteristics of plastic granulation melt gear pumps:
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.
Technical parameters of plastic granulation melt pump:
Transmission medium viscosity: 1~20000Pa • s (1000~20000000cP)
Inlet pressure 0-30MPa
Outlet pressure 0-40MPa
Large pressure difference of 25MPa
Operating temperature ≤ 350 ℃
Installation method of melt pump for granulation extruder:
The extrusion melt pump can be installed in multiple ways, and the input shaft of the pump can be arranged horizontally or vertically (both up and down); The drive system generally includes: motor, reducer, universal coupling, pump connection head, reducer connection head, etc;
The complete equipment includes a melt pump, inlet and outlet connectors, drive systems, control systems, etc. Customers can choose according to specific circumstances.
