    HK Series Polymer Melts Gear Pump
    HK series melt gear pump is especially suitable for the reaction and transportation of high temperature and high viscosity polymer melt requiring high output pressure, such as resin, chemical fiber and other industries. It is generally installed in the lower part of the reactor to make the 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 transported by melt gear pump are as follows:
    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
    Stock solution, solution, glue solution, oligomer and prepolymer in other polymer industry;
    It can also be used to transport hot melt adhesive, asphalt, paint, adhesive, pharmaceutical, food, grease, fuel, oil, dye, coating, lubricant, polyol and other materials without particulate impurities.
    Technical data:
    Viscosity : 1~30,000Pa•s (1,000~30,000,000cP)
    Suction side pressure : Vacuum(-0.05~-0.09MPa)~4MPa
    Discharge side pressure : 0~35MPa
    Differential pressure : 25MPa
    Temperature : ≤350℃
    Heating method : Fully Jacketed
    HTM pressure : ≤1.6MPa
    Installation method
    HK 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.
