Seim PB Pump: Performance and Reliability for Hydraulic Systems<\/strong><\/h3>\n

The Seim PB Pump is a three-screw pump specifically designed for low-flow applications (starting from 3 l\/min) and operating pressures up to 40 bar. Its design aims to meet technical requirements in industrial and marine environments, offering low maintenance costs and a long service life for internal components. <\/p>\n

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

The robustness of the Seim PB Pump comes from careful material selection and a compact design. <\/p>\n

    \n
  • Pump Body and Flanges<\/strong>: Made of spheroidal graphite cast iron UNI EN 1563 GJS400 (GGG40), a material that ensures high mechanical strength.<\/li>\n
  • Screw Set<\/strong>: The screws, the central component for fluid handling, are made of nitrided steel. This surface treatment provides high hardness and wear resistance.<\/li>\n
  • Seal<\/strong>: The system is equipped with a high-quality mechanical seal and Viton\u00ae O-rings, ensuring excellent chemical and thermal compatibility.<\/li>\n
  • Support and Bearings<\/strong>: The main shaft is supported by a radial ball bearing, lifetime lubricated to minimize maintenance.<\/li>\n
  • Relief Valve<\/strong>: The pump integrates an adjustable relief valve (up to 40 bar), protecting the circuit against overpressure.<\/li>\n<\/ul>\n

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

    The versatility of the Seim PB Pump makes it suitable for multiple technical uses. <\/p>\n

    Application Fields<\/strong><\/h3>\n

    Its design qualifies it for installations in both industrial and marine contexts. Typical applications include: <\/p>\n

      \n
    • Lubrication and pre-lubrication circuits<\/strong>.<\/li>\n
    • Burner and boiler feeding<\/strong>.<\/li>\n
    • Transfer systems<\/strong>, cargo handling, and fuel circulation.<\/li>\n
    • Auxiliary cooling circuits<\/strong>.<\/li>\n<\/ul>\n

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

      The pump is designed to handle a wide range of lubricating fluids: <\/p>\n

        \n
      • Hydraulic and lubricating oils<\/strong>.<\/li>\n
      • Mineral oils<\/strong>.<\/li>\n
      • Fuel oils<\/strong>: HFO, FO, DO, GO, ULSD, LSMGO.<\/li>\n<\/ul>\n

        Operating Data and Installation<\/strong><\/h3>\n
          \n
        • Flow Rate<\/strong>: Up to 200 l\/min (52 USGPM).<\/li>\n
        • Discharge Pressure<\/strong>: Up to 40 bar, for operating speeds between 1000 and 3600 rpm.<\/li>\n
        • Suction Pressure<\/strong>: Allowable from -0.7 to 10 bar.<\/li>\n
        • Viscosity<\/strong>: Standard range from 1.2 to 400 cSt; special versions available for viscosities up to 5000 cSt.<\/li>\n
        • Fluid Temperature<\/strong>: From 0 \u00b0C to 150 \u00b0C.<\/li>\n
        • Installation<\/strong>: The pump can be mounted in either horizontal or vertical position.<\/li>\n
        • Connections<\/strong>: Standard SAE type connections.<\/li>\n<\/ul>\n

          Version with Magnetic Coupling (Green Solution)<\/strong><\/h3>\n

          For applications where preventing any fluid leakage is crucial, the Seim PB Pump is also available with a magnetic coupling. This \u201cGreen\u201d solution eliminates the mechanical seal, creating a hermetically sealed system. It is the preferred choice for pumping environmentally hazardous fluids or in fire-risk areas, ensuring maximum safety, regulatory compliance, and significantly reduced maintenance costs. <\/p>\n
