Low pressure and high flow electric heating melt metering pumps are mainly used in the production process of polymers such as resins, chemical fibers, and other industries. They are used for reaction transportation and pressurization of materials with lower viscosity, lower output pressure, and high flow rate, such as polymer solutions, adhesives, monomers, oligomers, prepolymers, and other materials. It is generally installed in the melt pipe as a Booster pump, and can also be installed in the electrically heated extruder system as a metering pump.

The main characteristics of the electric heating polymer melt pumps are: 1. It can be applied to high temperature (350 ° C), high pressure (35MPa), high viscosity (30000Pa. s) working conditions; 2. The excitation flow pulsation is small, which can achieve near linear output of flow and is easy to control; 3. Good self priming performance, suitable for working conditions with vacuum inlet (-0.05~-0.08MPa); 4. Precision structure, high precision, and long service life.

Main structural materials of melt pump in extruder, pump casing: nitrided steel/Tool steel/stainless steel/Hastelloy; Gear: nitrided steel/Tool steel; Bearing: Tool steel/copper alloy/special alloy; Installation method: Multiple installation methods can be used, and the input shaft of the pump can be arranged horizontally or vertically (both upwards and downwards); The inlet and outlet directions of the pump can also be installed in any direction. The drive system generally includes motors, reducers, universal couplings, brackets, etc., and the flow control adopts variable frequency speed regulation.
