The FOX SL – SLX Series In-Line Tubular Diaphragm Pulsation Dampener<\/b> is a high-precision hydraulic component developed for pulsation control and fluid stabilization in high-pressure circuits. Designed to withstand severe operating conditions, this device is essential for preserving the mechanical integrity of pumps and piping, increasing the overall reliability of the hydraulic system.<\/p>\n

Operating Principle and Mechanical Life<\/h3>\n

Optimal performance of the FOX SL – SLX Series In-Line Tubular Diaphragm Pulsation Dampener is achieved by respecting specific compression parameters. The compression ratio recommended by the manufacturer is P2\/P0 = 2.5, while the maximum tolerated limit is set at P2\/P0 = 10. It is essential to consider that the mechanical life of the component, expressed as the number of cycles, is inversely proportional to the increase in the applied compression ratio. For correct use as a dampener, the nitrogen precharge pressure must be strictly maintained between 60% and 80% of the working pressure. This calibration must take into account the type of pump installed and the operating temperature values. The standard nitrogen valve supplied is listed in the catalogue as %” UNF.<\/p>\n

Construction Features<\/h3>\n

The structure of the dampener is designed to guarantee maximum strength and adaptability. The product line is divided into two main architectures:<\/p>\n

    \n
  • SLX Series:<\/b> Manufactured with an AISI 316L stainless steel body. This variant is designed as a repairable series, facilitating the replacement of internal components.<\/li>\n
  • SL Series:<\/b> Built with a carbon steel body and supplied by the manufacturer exclusively as a non-repairable series. The operating core of the device consists of the bladder, or tubular diaphragm, available in different elastomeric compounds to ensure chemical compatibility with multiple fluids: NBR, HNBR, EPDM, and FPM.<\/li>\n<\/ul>\n

    Installation, Applications and Dimensional Versions<\/h2>\n

    The component is designed for universal installation and can be effectively mounted in any position. In terms of pressure performance, the SLX model supports a maximum working pressure (PS) of 150 bar, while the SL model in carbon steel reaches 210 bar. Test pressures (PT) are established according to the regulatory multipliers PS x 1.43, 1.3, or 1.5.<\/p>\n

    Customizations and Hydraulic Connections<\/h3>\n

    To meet specific system requirements, the external body can be epoxy painted according to the standard FOX procedure or according to project specifications. Several connection configurations are also available, including:<\/p>\n

      \n
    • SAE 3000 or SAE 6000 flange, ANSI B16.5, UNI\/DIN.<\/li>\n
    • API Spec. 6A type 6BX connections.<\/li>\n
    • Autoclave or Grayloc connections.<\/li>\n
    • Integrated flange connections.<\/li>\n
    • Versions in special exotic materials on request.<\/li>\n<\/ul>\n

      Compliance and International Standards<\/h3>\n

      The dampener can be supplied, upon request, in compliance with a wide range of international certifications: CE (2014\/68\/EU-PED), KOSHA for Korea, ATEX (2014\/34\/EU), SELO for China, ASME VIII Div. 1 or Div. 2 (Latest Edition) with U-Stamp + NB, CU-TR 032\/2013 for Russia, DOSH for Malaysia, EN 14359, PD5500 for the United Kingdom, EN 13445, NR-13 for Brazil, CRN for Canada, as well as testing by bodies such as BV, AS1210\/4343 for Australia, DNV\/RINA, ARH for Algeria, and Lloyd\u2019s \/ ABS.<\/p>\n
