In recent years, with the continuous expansion of fields such as offshore engineering, chemical processes, and municipal environmental protection, the screw pump market has entered a new round of growth cycles.

Entering 2026, notable trends have emerged in the industry regarding application diversification, material upgrades, and intelligent operation and maintenance, driving both domestic and international manufacturers to accelerate technological innovation. As key equipment in fluid conveying, screw pumps have gradually extended from traditional oil & gas and marine industries to emerging sectors such as new energy, battery slurry, and bio-fermentation, with the industry landscape rapidly expanding.

I. Market Demand: Offshore Engineering and New Energy as New Growth Drivers

  1. Growing demand in offshore engineering
    Against the backdrop of deepwater oil & gas development, platform construction, and accelerated FPSO applications, screw pumps are widely used for conveying media containing sand, impurities, and gas due to their high stability and outstanding adaptability to complex media. Seawater corrosion, extreme climates, and continuous operation demand higher-quality pump body materials and sealing systems, prompting the industry to invest more R&D efforts in corrosion-resistant design.

  2. Steady growth in chemical and new materials industries
    Production lines in fine chemicals and new materials increasingly require pumping equipment capable of handling high-viscosity media, high cleanliness, and high stability. Screw pumps offer advantages such as low shear and no damage to material properties when conveying resins, colloids, and slurries, driving sustained demand.

  3. Emerging opportunities in new energy
    Applications such as power battery slurry, bio-fermentation broths, and specialty solvents impose high requirements on pump wear resistance, sealing structure, and flow stability. Some screw pump manufacturers have begun launching more precise conveying solutions tailored to these new industries.

II. Material Trends: Duplex Stainless Steel and High-End Alloys Become Mainstream Upgrades

From 2025 to 2026, significant material changes are occurring in the screw pump industry:

  1. Sharp increase in demand for duplex stainless steel (2205/2507)
    With the growing prevalence of seawater environments and corrosive media, duplex stainless steel, which combines strength and corrosion resistance, has become the preferred material for many offshore projects.

  2. Upgrades in wear-resistant alloys and surface treatment processes
    For high-solid-content and high-wear conditions, technologies such as specialized wear-resistant coatings (WC, Cr-based), nitriding hardening treatments, and high-nickel-based alloys are used to significantly improve pump lifespan and operational stability.

  3. Transition of elastomer materials from NBR to HNBR/FKM
    In environments with oil, solvents, or extreme temperatures, high-performance elastomers offer longer service life, representing a clear current trend.

III. Technological Innovation: Accelerated Adoption of Intelligent Monitoring and Modular Design

  1. Intelligent monitoring systems becoming a new standard feature
    Some manufacturers have integrated monitoring modules into pump bodies or pipelines, including vibration monitoring, temperature monitoring, pump body leak alarms, and runtime & maintenance alerts. This helps enhance safety in offshore and chemical projects.

  2. Modular structure reducing maintenance costs
    Users can quickly replace rotors, stators, bushings, and other components, shortening downtime and better meeting the maintenance needs of modern factories.

  3. Rapid growth of specialized screw pumps
    Examples include seawater corrosion-resistant screw pumps, high-temperature-resistant screw pumps, high-viscosity slurry screw pumps, and food-grade sanitary screw pumps. The industry is evolving from "general-purpose pumps" toward "specialized solutions."
