Wear Resistant Melt Gear Pump 0.6 12000cc for PP PE PET Extrusion
For PP, PE and PET plastic extrusion manufacturers running diverse production lines from small lab trials to high-capacity industrial production, a versatile, wear-resistant melt gear pump is the backbone of consistent output and low scrap rates. Our wear resistant melt gear pump covers a wide displacement range of **0.6~12000cc/r**, perfectly matching PP, PE and PET processing including film casting, sheet extrusion, pelletizing, fiber spinning and PET recycling lines.
Built on positive displacement metering principle, this melt gear pump delivers fixed volumetric flow per revolution. It isolates pressure pulsation generated by the extruder screw, stabilizes die pressure and flow rate, and frees the extruder to focus on plasticizing and homogenizing polymer melt rather than building pressure. Whether you process low-viscosity LDPE, medium-viscosity PP or high-temperature, easy-to-abrade PET melt, stable metering guarantees uniform thickness for sheets and films, consistent pellet size and fewer dimensional defects.
Wear resistance is the core design priority. Gear pairs, side plates and sealing mating surfaces adopt hardened wear-resistant alloy with precision grinding treatment. It stands up to long-term scouring by filled PP/PE, glass-filled PET and recycled polymer containing impurities, greatly slowing abrasive wear compared with standard nitrided steel pumps. This cuts frequent overhaul downtime and lowers your long-term spare part cost for continuous 24/7 extrusion operation.
Small displacement models (0.6–50cc/r)**: Ideal for lab extrusion, small-batch masterbatch, thin PP film and fine fiber production, offering ultra-fine flow control.
Medium displacement models (50–1000cc/r)**: Widely used for PE blown film, PP sheet, PET pelletizing and common compounding lines.
Large displacement models (1000–12000cc/r)**: Designed for high-output thick sheet, large-diameter pipe, PET flake recycling and heavy-capacity extrusion projects.
Equipped with standard heating channel design, the pump body supports thermal oil or electric heating to maintain uniform cavity temperature. It prevents melt stagnation and degradation for heat-sensitive PP and PET materials. Multiple sealing options are available: packing seal, spiral seal and combined mechanical seal to adapt to different melt temperature and pressure conditions. It can be matched with single-screw and twin-screw extruders seamlessly.
This melt gear pump is widely adopted in PP woven sheet, PE agricultural film, PET sheet, PET strapping band, recycled PET granulation and modified plastic compounding. It helps processors achieve 3 major benefits: tighter tolerance control, higher line throughput and lower energy consumption by reducing extruder backpressure load.
We support customized inlet/outlet flange size, rotation direction, heating form and surface treatment according to your working conditions. Every melt pump passes strict pressure and flow testing before shipment.
If you are sourcing a durable, full-range metering melt pump for PP, PE and PET extrusion lines, our wear resistant melt gear pump with 0.6~12000cc/r displacement covers your low-volume R&D and mass high-output production demands.
