2025-12-24 Plastic extrusion melt gear pump
Plastic extrusion melt pumps are critical equipment used in the plastic extrusion molding process for conveying, pressurizing, and metering high-temperature plastic melts. Working Principle A plastic extrusion melt pump is a positive displacement conveying device primarily composed of a pump housing, drive gear, and driven gear. The tooth profiles of the two gears, the pump body, and the side cover plates form the pumps feed zone, conveying zone, and discharge zone. When the gears rotate in the specified direction, the melt enters the gear tooth pockets in the feed zone. As the gears turn, the
2025-12-22 In which industries are melt gear pumps applied in industrial production?
Plastics and Resins Industry: Stable Extrusion, Enhanced Quality and Efficiency Industry Challenges: During the extrusion molding of plastic pipes, sheets, films, and other products, pressure and flow fluctuations in the melt output from screw extruders lead to uneven product thickness, large dimensional tolerances, numerous surface defects, and high scrap rates. BATTE Melt Pump Solution: Installed between the extruder and die head, it functions as both a booster pump and metering pump. By eliminating screw fluctuations, it delivers absolutely stable pressure and linear flow to the die head. T
2025-12-20 Melt pumps for sheet extrusion production lines
Melt pumps (melt gear pumps) play a central role in sheet extrusion production lines by stabilizing pressure and flow while enhancing plasticization quality. They are compatible with extrusion processes for various sheet materials including PP, PE, PET, PVC, and ABS, and are particularly suited for high-precision sheet production scenarios demanding wide widths and strict thickness tolerances. Precise Flow and Pressure Stabilization The extruder screws conveying action exhibits periodic fluctuations. The melt pump utilizes the volumetric delivery characteristic of gear meshing to control extru
2025-12-17 PE Water Ring Pelletizing Melt Pump
PE water-ring pelletizing melt pumps are predominantly gear-type melt pumps, serving as the core supporting equipment for PE water-ring pelletizing production lines. Installed between the extruder outlet and the pelletizing die, they are specifically engineered to accommodate the high-temperature, high-viscosity characteristics of PE melt. The following sections provide a detailed overview from three perspectives: core functions, key features, and selection and maintenance: Core Function Pressure and Flow Stabilization for Granulation Precision: When PE melt exits the extruder, pressure and fl
2025-12-13 Why has the melt pump outlet pressure decreased?
The core reasons for reduced melt pump outlet pressure can be categorized into three types: insufficient feed supply at the inlet end, pump body malfunction, and reduced load at the outlet end. Detailed analysis follows: Insufficient Feed Supply at the Feed End Extruder Feeding/Plasticizing Abnormalities: Material shortage in the extruder hopper, screw wear reducing conveying capacity, or poor raw material plasticization (low temperature, excessive moisture content) can cause material shortage on the melt pumps suction side, preventing sufficient pressure buildup. Feedline Blockage / Throttlin

2025-12-06 Hot Melt Adhesive Melt Pump
Hot melt adhesive pumps are positive displacement pumps that convey melt by altering the working volume through the meshing of drive and driven gears during operation. The working volume is formed by the pump body, gear tooth cavities, and bearing sleeves that function as side plates. As the gears rotate, the melt enters the suction chamber between the gear teeth. During rotation, the melt is drawn into the discharge chamber from both sides. When the gears re-engage, the melt in the tooth cavities is squeezed out of the discharge chamber and forced into the outlet pipeline. Standard lubricatin
