Choosing a manufacturer of melt gear pumps and comparing prices is the first habit of many people, but melt pumps are precision core equipment in production lines, and it is easy to fall into a trap just by looking at the price!
The focus of the assessment is on the four aspects of hard power
R&D and design capabilities
The viscosity, temperature pressure, and flow characteristics of different polymer materials vary. A good melt pump is not a universal standardized product. It needs to be customized according to the on-site working conditions, including displacement, gear structure, shaft system, seal and material, to match your material process.
Precision manufacturing capability
Melt gear pump belongs to high-precision volumetric conveying equipment. Gear machining accuracy, fit clearance, bearing and sealing structure directly affect volumetric efficiency, pressure stability, and service life. Insufficient accuracy can lead to pressure fluctuations, internal leakage, and premature equipment failure.
Engineering application experience
The same melt pump is used in PP granulation, BOPP film, PET sheet, chemical fiber spinning, and rubber extrusion, with completely different working conditions. Experienced manufacturers will select models based on the entire production line system, rather than simply recommending models based on flow rate.
After sales and technical service capabilities
Equipment delivery and installation are just the beginning, technical support is needed for temperature control debugging, startup procedures, speed and pressure matching, and operation and maintenance guidance. Continuous technical services are the guarantee for the long-term stable operation of equipment.
Price is just one of the reference items. Research and development, precision machining, on-site application experience, and technical services together determine whether the melt pump can be adapted to your production line. Comprehensive evaluation to reduce post production failures and lower long-term production costs.
