Pipeline Melt Pump Pressurization Pump

The core principle of the pipeline melt booster pump is based on positive displacement conveying. Through the meshing motion of a pair of high-precision gears, it achieves stable high-pressure delivery of the melt.

Its complete workflow can be divided into three closely interconnected stages: - Suction Stage: The drive gear rotates, causing the driven gear to rotate in the opposite direction. This increases the suction chamber volume within the pump body and creates negative pressure, efficiently drawing in the melt conveyed upstream.

During the conveying stage, the melt entering the gear pockets is securely enclosed by the gear structure. As the gears rotate, the melt is smoothly pushed from the feed zone to the discharge zone. This fully enclosed process ensures zero leakage and maintains constant flow rate.

During the pressurization stage, once the melt reaches the discharge chamber, the meshing gears squeeze the melt within the gear pockets to achieve active pressurization. This simultaneously isolates pressure fluctuations in the feed zone, precisely controlling outlet pressure variations within ±1%.
