Factory Supply gear oil hand pump - EHS Series Polymer Melts Gear Pump – Vowa Detail:
Booster Pump—— High-pressure，Electric Heating
EHS series melt gear pump
EHS 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, chemical fiber and other industries. They are generally installed in the melt pipeline and used as a booster pump; 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
The EHS series melt gear pump is generally installed in the melt pipeline at the bottom of the reactor and used as a booster pump or a metering pump. It is driven by a motor + reducer + universal coupling. The 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.
Main structure of gear pump:
Rotor type: helical or spur gear
Heating method: Heat medium heating
Sealing structure:
■ Dynamic melt seal + packing seal
■ Mechanical seal
■ Dynamic seal with cooling melt
■ High temperature resistant packing seal
Main structural materials of melt gear pump:
Pump casing: stainless steel/alloy steel/corrosion-resistant alloy
Gear: Nitrided steel/tool steel/stainless steel + coating/corrosion resistant alloy
Bearing: tool steel/copper alloy/stainless steel + coating/corrosion resistant alloy
