ESA and ESB Series Immersed Suction Filters UFI: Complete Protection for Hydraulic Pumps<\/strong><\/h3>\n

The ESA and ESB series by UFI Filters provide reliable solutions for filtration on the suction line, preventing the ingress of coarse contaminants into the hydraulic circuit and protecting the pump from premature damage. Designed to be installed directly inside the tank, below the oil level, these filters combine robust materials with advanced configuration options.<\/p>\n

Differences Between ESA and ESB Series<\/strong><\/h3>\n

Although they share the same basic structure and identical hydraulic performance, the two series differ in one key feature:<\/p>\n

    \n
  • ESA Series:<\/strong> Standard suction filter.<\/li>\n
  • ESB Series:<\/strong> Equipped with an integrated magnetic core made of sintered material, which retains ferrous metal particles suspended in the oil, providing an additional level of protection for system components.<\/li>\n<\/ul>\n

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

    The filters are manufactured using selected materials to ensure compatibility and durability:<\/p>\n

      \n
    • Connector and End Cap:<\/strong> Made of polyamide for standard sizes (up to series 43), while for larger sizes (51 and 52) the connector is aluminum and the end cap is galvanized steel, ensuring structural strength even at high flow rates.<\/li>\n
    • Bypass Valve:<\/strong> Integrated into the design (optional), made of polyamide.<\/li>\n<\/ul>\n

      Formula UFI Filter Elements<\/strong><\/h3>\n

      Filtration is performed by metal meshes from the FormulaUFI.WEB family, optimized for surface filtration on suction lines. Three filtration grades are available:<\/p>\n

        \n
      • ME:<\/strong> Metal mesh 60 \u00b5m.<\/li>\n
      • MF:<\/strong> Metal mesh 90 \u00b5m.<\/li>\n
      • MG:<\/strong> Metal mesh 250 \u00b5m. The element structure is designed to withstand a collapse differential pressure of 100 kPa (1 bar).<\/li>\n<\/ul>\n

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

        ESA \u2013 ESB UFI suction filters<\/strong> cover a wide range of application requirements:<\/p>\n

          \n
        • Maximum Flow Rate (Qmax):<\/strong> Up to 600 l\/min.<\/li>\n
        • Operating Temperature:<\/strong> From -25\u00b0C to +110\u00b0C.<\/li>\n
        • Bypass Valve:<\/strong> Available with a setting of 30 kPa (0.3 bar) \u00b110% to prevent cavitation in case of clogging or low temperatures (standard option \u201cA\u201d, or without bypass \u201cW\u201d for ESA; not available for ESB).<\/li>\n<\/ul>\n

          Compatibility and Connections<\/strong><\/h3>\n

          These filters are fully compatible with hydraulic fluids HH, HL, HM, HR, HV, and HTG according to ISO 6743\/4. Connection options include BSP and NPT threads, with sizes ranging from 3\/8″ up to 4″, ensuring maximum installation flexibility.<\/p>\n
