The melt pump specially developed by Batte for PVC is specialized in conveying, pressurizing and metering for polyvinyl chloride (PVC) high-viscosity polymer. PVC is a heat-sensitive material, which is sensitive to changes in temperature. During the extrusion process, it is easy to cause material carbonization, decomposition, and even coke phenomenon. The inlet of the PVC series special melt pump adopts a horn-type flow channel, and the internal flow channel and the structure of the gear are optimized. This structure is more suitable for the material properties of PVC.

Melt pump is a kind of positive displacement conveying equipment, 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 Cable, wire drawing, composite extrusion and other production lines have been widely used, and achieved good results.

PVC melt metering pump structure

The PVC melt ger pump is mainly composed of pump casing, driving gear, driven gear, sliding bearing, front and rear plates, packing seal, etc.

Advantages of PVC Melt Pumps

1. The optimized tooth shape design makes the conveying more stable and the fluctuation is extremely small.
2. The flow channel design without dead angle, no material residue.
3. Easier sealing method.
4. Optional wear-resistant configuration, suitable for high filling conditions.

PVC melt pump installation structure

It is recommended to use a universal coupling to connect the reducer and the melt pump to eliminate the influence of thermal deformation; the melt pump is a positive displacement pump, and the output flow of the pump can be adjusted by adjusting the speed of the pump. Frequency conversion speed regulation is recommended. In this way, the near-linear flow output of the gear pump can be realized. info@battemachinery.com
