Seim PCX WTG Pump: Performance and Reliability for the Hydraulic Sector<\/strong><\/h3>\n

The Seim PCX WTG Pump is a self-priming twin-screw pump designed to meet the most demanding requirements in applications with hydraulic and lubricating oils, even in the presence of dissolved gases. Its advanced architecture makes it an optimal solution for lubrication and auxiliary cooling systems, particularly in the industrial, Oil & Gas, and marine sectors.<\/p>\n

Operating Principle and Advantages<\/strong><\/h3>\n

The design of the PCX WTG is based on a two-screw configuration without timing gears. This construction choice translates into significant advantages:<\/p>\n

    \n
  • High flow capacity<\/strong>: Ideal for applications with lubricants and fuels.<\/li>\n
  • Low noise and vibration<\/strong>: The absence of gears reduces acoustic emissions and mechanical stresses.<\/li>\n
  • Self-priming capability<\/strong>: Simplifies system installation and start-up.<\/li>\n
  • Consistent performance<\/strong>: Ensures a stable and predictable flow over time.<\/li>\n
  • Wide viscosity range<\/strong>: Capable of handling fluids with kinematic viscosity from 5 up to 25000 cSt.<\/li>\n<\/ul>\n

    Construction Features and Materials<\/strong><\/h3>\n

    The robustness and versatility of the Seim PCX WTG Pump derive from a careful selection of materials and a mechanical design optimized for maximum durability.<\/p>\n

    Mechanical Design<\/strong><\/h3>\n

    The pump is equipped with a single mechanical seal, with the option to install seals compliant with API 682 standard upon request. The internal bearings are lubricated directly by the pumped fluid. The structure includes a fabricated external casing and a fully removable and replaceable inner liner, facilitating maintenance operations. Installation can be either horizontal or vertical, offering maximum integration flexibility. On request, a magnetic coupling version is also available.<\/p>\n

    High-Quality Materials<\/strong><\/h3>\n
      \n
    • Pump Body and Flanges<\/strong>: Welded steel (A105 or equivalent), AISI 316L Stainless Steel, or Duplex.<\/li>\n
    • Screws (Primary and Driven)<\/strong>: Hardened Carbon Steel or AISI 410 Stainless Steel.<\/li>\n
    • Inner Liner<\/strong>: Cast Iron (A48 Gr.35 or GG25), Carbon Steel, or Stainless Steel.<\/li>\n
    • O-rings<\/strong>: Standard in Viton.<\/li>\n<\/ul>\n

      Operating Specifications and Performance<\/strong><\/h3>\n

      The PCX-WTG series offers a wide operating window to adapt to different process conditions.<\/p>\n

      Functional Characteristics<\/strong><\/h3>\n
        \n
      • Flow Rate<\/strong>: Up to 9000 l\/min.<\/li>\n
      • Allowable Differential Pressure<\/strong>: Up to 16 bar.<\/li>\n
      • Allowable Suction Pressure<\/strong>: from -0.7 to 10 bar.<\/li>\n
      • Allowable Fluid Temperature<\/strong>: from -50\u00b0C to 300\u00b0C.<\/li>\n
      • Rotational Speed<\/strong>: from 750 to 3600 rpm.<\/li>\n<\/ul>\n

        Compatible Fluids<\/strong><\/h3>\n

        The pump is designed to operate with a wide range of fluids, including:<\/p>\n

          \n
        • Mineral oils and lubricants.<\/li>\n
        • Hydraulic and diathermic oils.<\/li>\n
        • Organic esters (DFD-U) and phosphate esters (HFDR).<\/li>\n
        • Water-glycol.<\/li>\n
        • Light and heavy fuel oils.<\/li>\n
        • Asphalt and bitumen.<\/li>\n<\/ul>\n

          The pump is suitable for fluids with a solid content of 0%.<\/p>\n

          The PXWTG 042-040 Variant<\/strong><\/h3>\n

          The series also includes the specific PXWTG 042-040 model, optimized for hydraulic, lubricating, and corrosive oils, even with dissolved gases. This variant operates at a rotational speed of 1450 rpm and features a standard differential pressure of 2 bar, extendable up to 10 bar with mineral oil. It is designed for kinematic viscosities from 1 to 10 cSt.<\/p>\n

          Inspection and Compliance<\/strong><\/h3>\n

          Each pump undergoes rigorous quality checks, including visual and dimensional inspection of materials, automatic dimensional control of screws, and hydrostatic tests. For API-compliant units, performance and hydrostatic tests are carried out according to API 676 standard.<\/p>\n
