 G series melt gear pump is especially suitable for high temperature and high viscosity polymer melt reaction transportation 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 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
 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      : vacuum(-0.05~-0.09MPa)~4MPa
 Discharge side pressure    : 0~35MPa
    Differential pressure      : 25MPa  
   Temperature                : ≤350℃
   Heating                    : Hot coal heating
    HT medium pressure         : ≤1.6MPa
 Installation method
G 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.
Main structure of gear pump:
