Melt pump for TPU thermoplastic elastomers

TPU elastomer melt pump is a specialized extrusion system for rubber and elastomer melt gear pump, which is suitable for the extrusion and transportation of rubber and elastomer melts; Generally installed between the outlet of the extruder and the die head, used as a melt metering pump; The pump casing of the TPU elastomer melt pump has a built-in flow channel, which can be used for cooling or heating the heating medium.

Installation method of 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 belongs to 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 nearly linear flow output of the gear pump.

Melt pump selection parameters

The selection needs to provide parameters: 1. Flow rate or output; 2. Material name; 3. Material viscosity; 4. Corrosiveness/toxicity of materials; 5. Inlet and outlet pressure (pressure difference); 6. Operating temperature. The flow rate of the melt pump is related to the working speed, material viscosity, and working pressure. Please consult the manufacturer for specific selection.
