    High-pressure,Channel-Heating

    DHS series melt gear pump
    DHS series melt gear pumps are especially suitable for the reactive transportation and pressurization of high-temperature and high-viscosity polymer melts that require high output pressure, such as resin and chemical fiber industries. They are generally installed in melt pipelines and used as booster pumps; also It can be installed in the extruder system that needs heating medium to be used as a metering pump. This series of melt gear pumps have a certain self-priming performance, and can be used for conveying and pressurizing polymer materials under lower vacuum suction 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 : 1~30,000Pa•s (1,000~30,000,000cP)
    Suction side pressure :(-0.00~-0.03MPa)~16MPa
    Discharge side pressure : 0~35MPa
    Differential pressure : 25MPa
    Temperature : ≤350℃
    Heating : Fully Jacketed
    HT medium pressure : ≤1.6MPa
    Installation method
    DHS series melt gear pumps are generally installed in the melt pipeline at the bottom of the reactor and used as booster pumps or metering pumps. They are driven by motor + reducer + universal coupling. Melt gear pumps are positive displacement pumps. , The output flow of the pump can be adjusted by adjusting the speed of the pump. Frequency conversion speed regulation is recommended, which can realize the nearly linear flow output of the gear pump.
