    DLK-Series-Polymer-Melts-Gear-Pump1

    DLK Series Polymer Melts Gear Pump
    DLK series melt gear pumps are suitable for the reaction transportation of high temperature and high viscosity polymer melts that require low output pressure and large flow, such as resin, chemical fiber and other industries. They are generally installed in the lower part of the reactor and used as a feed pump. This series of melt gear pumps have good self-priming performance and can be used for conveying and pressurizing polymer materials under vacuum reaction conditions.
    The main materials that can be conveyed by the melt gear pump are:
    Polymer melt
    PET PBT PTT
    PA6 PA66 PA12
    PE LDPE LLDPE HDPE HMWPE
    PP EVA PB
    PB PS HIPS ABS SAN
    PC PEK PMMA POM
    TPU PLA PBS
    Other stock solutions, solutions, glues, oligomers, prepolymers, etc. in the polymer material industry;
    It can also be used to transport hot melt adhesives, asphalt, paints, adhesives, pharmaceuticals, food, grease, fuels, oils, dyes, coatings, lubricants, polyols and other materials that do not contain particulate impurities.
    Technical data:
    Viscosity : 1E-3~30,000Pa•s (1~30,000,000cP)
    Suction side pressure :(-0.05~-0.09MPa)~4MPa
    Discharge side pressure : 0~7MPa
    Differential pressure : 5MPa
    Temperature : ≤350℃
    Heating : Fully Jacketed
    HT medium pressure : ≤1.6MPa
    Installation method
    DLK series melt gear pumps are generally installed at the bottom of the reactor and are driven by a motor + reducer + universal coupling. The melt gear pump is a positive displacement forced delivery pump. The pump output flow can be adjusted by adjusting the pump speed. It is recommended Using frequency conversion speed regulation, can realize the nearly linear flow output of the gear pump.main2

    Main structure of gear pump:
    Rotor type: helical or spur gear
    Heating method: Heat medium heating
    Sealing structure:
    ■ Dynamic melt seal + packing seal
    ■ Mechanical seal
