Polymer melt pump in nylon pipe extrusion line

The melt pump plays a critical role in nylon pipe production, specifically engineered for nylon materials and extrusion processes. Featuring a precision gear-meshing structure, this pump delivers exceptional accuracy with flow rate deviation of ≤±1%. It ensures stable melt delivery to the die head, enabling precise control over pipe wall thickness. This minimizes fluctuations that cause wall thickness variations, thereby enhancing product yield rates.

Addressing nylon melt's high processing temperatures, the pump utilizes a high-temperature alloy housing and wear-resistant gear wheels to withstand extreme heat and pressure. Its optimized flow channel design minimizes melt retention, preventing nylon degradation and ensuring the pipe's mechanical properties—including impact resistance and aging resistance.

Additionally, its powerful pressure compensation function balances delivery pressure fluctuations, maintaining stable inlet pressure to the die head. This prevents rough inner walls and non-circular outer diameters in pipes, optimizing forming quality.
