ZB-G bearing external melt pump series is suitable for occasions where the melt has poor self-lubrication after melting, contains a small amount of solid particles, and wears a lot of related components such as the extruder and melt pump, and the conventional melt pump cannot meet the requirements. Such as: wood plastic powder. External lubrication is adopted to solve the defect of poor melt fluidity, which is not suitable for self-lubricating. The disadvantage is that the structure is more complicated than the conventional melt pump, and the cost is also higher than that of the conventional melt pump.

The bearing external melt pump is suitable for harsh working conditions. Compared with the traditional melt pump internal self-lubricating system, the external lubrication is more suitable for use in harsh working conditions. When the polymer contains many infusible substances, such as calcium carbonate particles, carbon particles, glass fibers, etc., it is easy to coalesce in the lubricating flow passage under high temperature for a long time, blocking or blocking the lubricating passage. If there is no passage, the gear shaft and the shaft sleeve are easily locked by dry grinding, and the problem of using an externally lubricated melt pump can be solved. Four imported bearings are used to fix the driving shaft and the driven shaft outside the pump body. According to The viscosity of the material and the operating temperature should be optimized accordingly to the internal structure of the melt pump, as well as the sealing and matching clearance.

Melt pump is mainly used for conveying, pressurizing and metering of high temperature and high viscosity polymer melt. Its main function is to pressurize and stabilize the high-temperature melt from the extruder, and keep the melt flow accurately and stably fed into the extruder head. Today, melt gear pumps have been widely used in chemical fiber, granulation, plastic film, sheet, plate, profile, pipe, wire and cable, wire drawing, composite extrusion and other production lines, and the processable materials almost cover most polymers. Materials such as: PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymers, polysulfones, polyesters, thermoplastic elastomers, rubbers and thermal adhesives, etc. Batte melt gear pump is a positive displacement conveying equipment. The high-precision gear gap and volumetric structure design make stable and balanced extrusion possible. In chemical fiber, granulation, plastic film, sheet, plate, profile, pipe , wire and cable, wire drawing, composite extrusion and other production lines have been widely used, and achieved good results. info@battemachinery.com
