Vacuum Reactor Discharge Pump—— Medium And Low Pressure, Full Jacket


LK Series Polymer Melts Gear Pump
LK 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-330000Pa•s 130,000,000cP
Suction side pressure :(-0.05-0.09MPa)~4MPa
Discharge side pressure 07MPa
Differential pressure 5MPa
Temperature ≤350℃

HT medium pressure ≤1.6MPa


Installation method
LK 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.
