Operating Features and Compatible Fluids<\/strong><\/h3>\n

The Seim PHS Pump is designed to operate across a wide range of conditions, ensuring maximum flexibility in industrial and marine contexts. Its three-screw configuration guarantees a constant, pulsation-free flow, essential for handling delicate fluids and for the stability of hydraulic circuits.<\/p>\n

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

The pump is suitable for pumping a wide variety of fluids, including:<\/p>\n

    \n
  • Fuel oil (HFO-DO-LSMGO)<\/li>\n
  • Hydraulic oils and lubricating oils<\/li>\n
  • GO and ULSD<\/li>\n<\/ul>\n

    The standard kinematic viscosity range goes from 1.2 to 400 cSt, with special versions capable of handling fluids up to 5000 cSt. The operating temperature ranges from 0 to 150 \u00b0C.<\/p>\n

    Operating Parameters<\/strong><\/h3>\n

    The PHS series operates at rotational speeds from 750 to 3600 rpm. The permissible suction pressure ranges from -0.5 to 10 bar, while the continuous discharge pressure reaches 16 bar for speeds between 1000 and 3600 rpm. The maximum flow rate reaches up to 170 l\/min (10.2 m\u00b3\/h), depending on the model and operating conditions. The standard rotation is clockwise (CW), with a counterclockwise (CCW) version available upon request.<\/p>\n

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

    The robustness and reliability of the Seim PHS Pump derive from the careful selection of materials and an optimized design for durability.<\/p>\n

    Main Components<\/strong><\/h3>\n
      \n
    • Body and Flanges<\/strong>: Made of spheroidal graphite cast iron GGG40, ensuring high mechanical and pressure resistance.<\/li>\n
    • Screws<\/strong>: The screw set is made of nitrided steel, a material that offers excellent wear and fatigue resistance, even with low-lubricity fluids.<\/li>\n
    • Seals<\/strong>: The shaft seal is provided by a high-quality mechanical seal, while the O-rings are made of Viton\u00ae to ensure chemical compatibility with a wide range of fluids and temperatures.<\/li>\n
    • Bearing<\/strong>: The main shaft is supported by a radial ball bearing, lifetime lubricated to minimize maintenance.<\/li>\n
    • Safety Valve<\/strong>: The pump integrates a pressure relief valve (maximum pressure valve) with adjustable setting, to protect the circuit from possible overpressures.<\/li>\n<\/ul>\n

      Applications and Installation Fields<\/strong><\/h3>\n

      The versatility of the Seim PHS Pump makes it the ideal solution for numerous critical applications, especially in the marine sector.<\/p>\n

      Typical Applications<\/strong><\/h3>\n

      Pumps of this series are used in:<\/p>\n

        \n
      • Separator and booster systems<\/strong><\/li>\n
      • Fuel supply circuits (feeder and fuel supply)<\/strong><\/li>\n
      • Transfer and cargo operations<\/strong><\/li>\n
      • Auxiliary lubrication and cooling circuits<\/strong><\/li>\n
      • Circulation systems for heaters<\/strong><\/li>\n<\/ul>\n

        Installation and Certifications<\/strong><\/h3>\n

        The pump can be installed both indoors and outdoors and allows for horizontal or vertical mounting. The product is ABS approved (TYPE APPROVED PRODUCT) and additional certifications such as DNV, Lloyd’s Register, and Korean Register (KR) are available upon request.<\/p>\n
