1. Optimized melt flow channel design: eliminate dead corners in the flow channel, reduce polymer residues to a minimum, and improve the quality of products;
2. Optional built-in flow channel: suitable for fluid cooling to adapt to a more accurate and fast temperature control system; it can also be used for heat medium heating;
3. Improved gear parameter design: more precise rotation displacement design makes the output pressure more stable and adapts to precise extrusion conditions;
4. A wide range of applicable viscosity: different sealing methods can be applied to working conditions from low viscosity to very high viscosity;
5. A variety of installation methods: to meet the individual needs of users;
6. High-precision manufacturing and excellent heat treatment: more precise and more durable;
Technical data:
Viscosity ： 1E-3～40000Pa•s（1～40,000,000cP）
Suction side pressure ： 0～30MPa
Discharge side pressure ： 0～40MPa
Differential pressure ： 25MPa
Temperature ： ≤350℃
Heating ： Electric heating/heating medium channel heating
The installation structure of melt gear pump:
It is recommended to use a universal coupling to connect the reducer and the melt pump to eliminate the effects of thermal deformation; the melt gear pump is a positive displacement forced delivery pump, and the pump output flow can be adjusted by adjusting the pump speed. Frequency conversion is recommended. The speed mode can realize the nearly linear flow output of the gear pump.

The flow rate of the melt gear pump is related to the working speed, material viscosity, and working pressure. Please consult the manufacturer for specific selection.
The selection needs to provide parameters: 1 flow or output 2 material name 3 material viscosity 4 material corrosivity/toxicity 5 inlet and outlet pressure (pressure difference) 6 operating temperature
In addition, according to the actual situation and requirements of the customer, you can choose the pump casing configuration without flow channel
