BATTE ZB-D pipeline melt pump

A pipeline melt pump is a specialized device designed for the conveyance, pressurization, and metering of high-temperature, high-viscosity polymer melts, playing a critical role in industries such as plastics, rubber, and chemical fibers. Below is a detailed introduction covering its working principle, structural features, application advantages, technical parameters, and selection recommendations:

Application Advantages

Stable Flow and Pressure: The melt pump effectively isolates pressure and flow fluctuations from upstream equipment (such as an extruder), ensuring stable operation of downstream equipment and improving product quality.

Enhanced Extrusion Precision: By precisely controlling the pump's rotational speed, linear output of the melt flow rate can be achieved, suitable for precision extrusion systems and significantly improving the dimensional accuracy and surface quality of extruded products.

Energy Savings: The melt pump transfers the pressure-reducing function of the extruder to itself, allowing the extruder to operate under low-pressure and low-temperature conditions, reducing leakage flow and energy consumption.

Extended Equipment Lifespan: After using a melt pump, the pressure within the extruder barrel is reduced, minimizing wear between the screw and barrel and extending the equipment's service life.

Adaptability to High-Viscosity Media: Capable of handling melts with viscosities up to 4000 Pa·s (4,000,000 cP), suitable for processing various polymer materials.

Technical Parameters

The main technical parameters of the pipeline melt pump include:

Displacement Range: 0.1 cc/r ~ 12000 cc/r (displacement per revolution).

Output Pressure: 0 ~ 40 MPa.

Suction Pressure: Vacuum (-0.05 ~ -0.08 MPa) ~ 30 MPa.

Operating Temperature: ≤400°C.

Viscosity of Conveyed Medium: 1 ~ 4000 Pa·s (1000 ~ 4,000,000 cP).

Heating Method: Electric heating or heat transfer oil heating.

Driving Method: Motor + reducer + universal coupling at the pump end.

Flow Adjustment: Variable frequency speed control.

Control System: Pressure closed-loop control (intelligent instrument + inverter or servo driver, PLC + inverter or servo driver).

Application Fields

The pipeline melt pump is widely used in the following fields:

Plastics Processing: Extrusion molding of sheets, plates, pipes, films, profiles, etc.

Rubber Industry: Extrusion and conveyance of rubber and elastomer melts.

Chemical Fiber Industry: Conveyance and metering of chemical fiber raw materials such as polyester and nylon.

Pipeline Conveyance: Smooth pressurized conveyance of high-viscosity media in polymer fluids.

Compounding Extrusion: Used in series with single-screw or twin-screw extruders to improve compounding quality and output.
