DLS Series Polymer Melts Gear Pump
DLS series melt gear pumps are suitable for reaction delivery and pressurization of high-temperature and high-viscosity polymer melts with lower output pressure, such as resin, chemical fiber and other industries. They are generally installed in melt pipelines and used as booster pumps; The body gear pump has a certain self-priming performance, and can be used to transport and pressurize 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 ： 1E-3～30，000Pa•s （1～30,000,000cP）
Suction side pressure ：（-0.00～-0.03MPa）～5MPa
Discharge side pressure ： 0～5MPa
Differential pressure ： 5MPa
Temperature ： ≤350℃
Heating ： Fully Jacketed
HT medium pressure ： ≤1.6MPa
Installation method
DLS 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, or motor + reducer + flexible coupling. Shaft drive. Melt gear pump is a positive displacement forced delivery pump. 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.
