100% Original micro gear pump - EHK Series Polymer Melts Gear Pump – Vowa Detail:
Vacuum Reactor Discharge Pump—— High Pressure, Electric Heating
EHK Series Polymer Melts Gear Pump
The EHK series melt gear pump is especially suitable for the reaction and transportation of high-temperature and high-viscosity polymer melts that require high output pressure, such as resin, chemical fiber and other industries. It is 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.

Suction side pressure : Vacuum(-0.05~-0.09MPa)~4MPa
Discharge side pressure : 0~35MPa
Differential pressure : 25MPa
Temperature : ≤350℃
Heating method : Fully Jacketed
HTM pressure : ≤1.6MPa
Installation method
The EHK series melt gear pump is generally installed at the bottom of the reactor and is 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:
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
