Twin-screw pump (parallel pump)

Through optimized design, we have addressed common shortcomings of screw pumps while further enhancing their advantages: gentle conveying, minimal temperature rise, and ease of servicing and maintenance. Consequently, we can provide suitable solutions tailored to your specific needs. Dual-screw pumps operate on an axial delivery principle, ensuring smooth operation even under extremely high system pressures, with low vibration and no pulsation. Additionally, the mechanical seals in dual-screw pumps are less prone to damage under constant pressure and eliminate cleaning dead zones. Their compact structure allows for both horizontal and vertical installation options. Modular design makes Zicionpumps easier to inspect and maintain; replacing components such as mechanical seals and screws is quick and straightforward, effectively reducing maintenance time. High-quality materials combined with advanced manufacturing processes further enhance the reliability of dual-screw pumps.

    Applicability

    Twin-screw pumps have been successfully applied in a wide range of challenging applications. Their well‑thought‑out design enables them to perfectly suit diverse customer needs and meet the requirements of various applications.

    A single twin-screw pump can gently handle fluids of varying viscosities and flow rates with exceptional efficiency.

    • It can convey media of both high and low viscosity, including non-Newtonian fluids and gases with a relatively high gas content.
    • Operates at both low and high temperatures, and can even be used in ultra-high-temperature conditions.
    • It continues to operate stably even under low NPSH conditions.
    • No pulse, low vibration.
    • High work efficiency.
    • The non-contact twin-screw design prevents residue after cleaning.


    Zicionpumps twin-screw pumps can overcome physical limitations and handle even the most demanding material pumping applications.
