Melt gear pump for polyurethane elastomer rubber
The melt pump for TPU elastomer is a melt gear pump for the extrusion system dedicated to rubber and elastomers. It is suitable for extrusion and transportation of rubber and elastomer melts; it is generally installed between the extruder outlet and the die. , used as a melt metering pump; the pump housing of the TPU melt pump has a built-in flow channel, which can be used for cooling or heat medium heating.
Features of thermoplastic melt pump for TPU elastomer
1. Optimized melt flow channel design: eliminate dead corners in the flow channel, reduce polymer residue to a minimum, and improve product quality;
2. Optional built-in flow channel: suitable for fluid cooling to adapt to a more precise and rapid temperature control system; it can also be used for heat medium heating;
3. Improved gear parameter design: more accurate rotation and displacement design, making the output pressure more stable and suitable for precision extrusion conditions;
4. Extremely wide applicable viscosity range: using different sealing methods, it can be applied to working conditions from low viscosity to extremely high viscosity;
5. Multiple installation methods: to meet the personalized needs of users;
6. High-precision manufacturing and excellent heat treatment: more precise and more durable.
Thermoplastic melt pump manufacturer parameters for TPU elastomer

Installation method of thermoplastic melt pump for TPU elastomer
It is recommended to use a universal coupling to connect the reducer and melt pump to eliminate the influence 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. It is recommended to use variable frequency adjustment. Speed mode can achieve near-linear flow output of the gear pump.
