What are the classifications of melt pump models?

The model selection for melt pumps is extremely diverse, with specific models and their related parameters outlined below:

I. Classification by Displacement

The displacement range of melt pumps is vast, ranging from small to large as follows: 0.1cc, 0.5cc, 1cc, 2cc, 5cc, 10cc, 20cc, 31.5cc, 50cc, 100cc, 150cc, 200cc, 315cc, 500cc, 800cc, 1200cc, 2500cc, 3200cc, 4000cc, 6100cc, 8500cc, and 12000cc, among others. Here, "X cc" indicates that the displacement per revolution of the melt pump is X cc. For example, a 5cc melt pump has a displacement of 5cc, or 5ml, per revolution. Additionally, some companies can provide non-standard manufacturing based on users' actual production needs.

II. Considerations for Model Selection

When selecting a melt pump model, the following factors need to be comprehensively considered:

Flow Rate Requirements: Choose a melt pump based on the material flow rate required in the production process, ensuring its flow rate range meets actual production needs. Additionally, the stability and linearity of the flow rate output should meet product quality control requirements.

Pressure Conditions: Clarify the pressure range and stability requirements in the application scenario. For example, in high-pressure environments, a melt pump that can withstand the pressure and operate stably should be selected.

Material Characteristics: If handling materials with high viscosity or chemical properties such as corrosion, a melt pump suitable for these materials should be chosen to avoid clogging or poor flow.

Working Environment: For melt pumps operating in high-temperature environments, ensure that their materials and structure can withstand high temperatures without deformation, damage, or performance degradation affecting service life.

Individualized Needs: If there are special structural or material requirements in the production process, select an appropriate melt pump based on these individualized factors. For example, some users may require specific installation dimensions, connection methods, or special cleaning methods for the melt pump.

In summary, the model selection for melt pumps is abundant and requires comprehensive consideration and selection based on actual production needs, material characteristics, working environments, and individualized needs.
