Marzocchi Gear Pumps Series 1P<\/strong> represent an optimal solution for compact hydraulic systems requiring reliability, versatility, and reduced size<\/strong>. Designed for low- and medium-power applications, they are widely used in power units<\/strong> and in areas where compact dimensions<\/strong>, continuous operation<\/strong>, and excellent volumetric and hydro-mechanical efficiency<\/strong> are required.<\/p>\n

Constructed with a high-strength extruded aluminum body, die-cast flanges and covers, and gears made of case-hardened, tempered, and ground steel, these pumps ensure low noise levels<\/strong>, limited flow pulsation<\/strong>, and high mechanical durability<\/strong>, even under high pressure.<\/p>\n

Components and Materials<\/h3>\n

The pumping group consists of a pair of gears supported by die-cast aluminum alloy bushings<\/strong>, equipped with radial and axial compensation areas, sealed with anti-extrusion rings<\/strong>. This system drastically reduces internal leakage, allowing stable volumetric efficiency even under demanding conditions.<\/p>\n

Each 1P pump is equipped with a double-lip seal ring<\/strong>, functioning as both internal seal and external dust wiper, secured by a retaining ring. \u201cQ\u201d versions include the seal ring already installed.<\/p>\n

Wide Range of Configurations<\/h3>\n

The 1P range includes:<\/p>\n

    \n
  • \n

    Unidirectional versions<\/strong> (D or S, right or left rotation)<\/p>\n<\/li>\n

  • \n

    Reversible versions<\/strong> (R) with external drain<\/p>\n<\/li>\n

  • \n

    Double versions<\/strong> (e.g. 1P D 2 + 1P D 3.3)<\/p>\n<\/li>\n

  • \n

    Special versions<\/strong>:<\/p>\n

      \n
    • \n

      \u201cV\u201d for high temperatures (up to +150\u00b0C, max 20 bar)<\/p>\n<\/li>\n

    • \n

      \u201cST\u201d for low\/high temperatures (-40\u00b0C \u00f7 +120\u00b0C)<\/p>\n<\/li>\n

    • \n

      \u201cTR\u201d for pressurized suction up to 6 bar<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

      Pumps can be supplied with an integrated pressure relief valve (VM model)<\/strong>, with internal (DI) or external (DE) drainage. Reversible versions must be equipped with external drainage.<\/p>\n

      Performance<\/h3>\n
        \n
      • \n

        Displacements<\/strong> from 1.1 to 11.5 cm\u00b3\/rev<\/p>\n<\/li>\n

      • \n

        Theoretical flow rates<\/strong> from 1.6 to 11.9 l\/min at 1500 rpm<\/p>\n<\/li>\n

      • \n

        Maximum pressures<\/strong>: up to 270 bar (P3), 250 bar (P2), 230 bar (P1)<\/p>\n<\/li>\n

      • \n

        Maximum speed<\/strong>: up to 6000 rpm (smaller models), 2100 rpm (size 11.5)<\/p>\n<\/li>\n

      • \n

        Minimum speed<\/strong>: from 1000 to 1500 rpm depending on the size<\/p>\n<\/li>\n<\/ul>\n

        Compatible Fluids and Operating Conditions<\/h3>\n

        1P pumps must use mineral oils for hydraulic systems<\/strong> compliant with DIN 51525 and VDMA 24317. Fluids should have a viscosity between 10 \u00f7 100 cSt (recommended), with start-up tolerance up to 2000 cSt. Operating temperatures range from -15\u00b0C to +80\u00b0C for standard versions, and up to +120\u00b0C for \u201cV\u201d versions.<\/p>\n

        It is essential to ensure adequate filtration levels, with ISO 4406 class 18\/15 or better<\/strong>. For versions with servovalves, a filter of 5 \u03bcm absolute or finer is required.<\/p>\n
