Wesentliche Merkmale und Vorteile<\/span><\/h3>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Professionally remanufactured to OEM specifications<\/span><\/strong><span class=\"\">\u00a0\u2013 This main hydraulic pump (OEM 9184686) has been fully disassembled, cleaned, inspected, and rebuilt in our ISO\u2011certified facility in China. Worn components \u2013 cylinder block, piston assemblies, valve plate, swashplate, bearings, seals \u2013 are replaced with new, high\u2011quality parts. The result is a pump that delivers performance and reliability comparable to a new unit at a fraction of the cost.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Original Hitachi specification for ZAX450\u20116<\/span><\/strong><span class=\"\">\u00a0\u2013 The 9184686 is the direct replacement for the 40\u2011ton class ZAX450\u20116, ZX450, and related models. It restores the factory hydraulic power, flow, and pressure characteristics that your machine was designed to deliver.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Tandem variable displacement axial piston design<\/span><\/strong><span class=\"\">\u00a0\u2013 Two independent pumping sections in one housing power the travel, swing, boom, arm, and bucket circuits simultaneously. This design allows smooth, coordinated operation even under heavy load \u2013 no power loss when you need to combine functions.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Restored flow and pressure<\/span><\/strong><span class=\"\">\u00a0\u2013 After remanufacturing, this pump delivers rated working pressure of approximately 34\u201335 MPa (\u22484,900\u20135,100 psi) and a total flow of over 400 L\/min (two main sections plus integral gear pump). Your ZAX450\u20116 regains full digging force, fast cycle times, and responsive travel.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Integriertes Leistungsregelungs- (Load-Sensing-) System<\/span><\/strong><span class=\"\">\u00a0\u2013 The rebuilt pump retains the factory power control system, which matches pump output to actual working load. This reduces fuel consumption, prevents engine stall, and extends the life of both the pump and the hydraulic system. The integral pilot gear pump is also rebuilt to supply the control circuit.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Kosteng\u00fcnstige Alternative zum neuen Original<\/span><\/strong><span class=\"\">\u00a0\u2013 A new genuine Hitachi main pump for a 40\u2011ton excavator is a significant investment. Our remanufactured 9184686 gives you the same fit, form, and function at a much lower price, without sacrificing reliability. Each pump is tested on a hydraulic test stand before dispatch.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Direkter Schraubersatz (Plug-and-Play)<\/span><\/strong><span class=\"\">\u00a0\u2013 Montageflansch, Antriebswellenverzahnung und Hydraulikanschlusskonfigurationen werden auf die urspr\u00fcnglichen Hitachi-Spezifikationen zur\u00fcckgesetzt. Keine Modifikationen, keine Adapter, keine Anpassungsarbeiten \u2013 Ihr Mechaniker schraubt die alte Pumpe ab und die neue an.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Sichtpr\u00fcfung vor dem Versand<\/span><\/strong><span class=\"\">\u00a0\u2013 Vor der Verpackung senden wir Ihnen detaillierte hochaufl\u00f6sende Fotos des tats\u00e4chlich wiederaufbereiteten Aggregats (Montageflansch, Verzahnungen, Anschlussgewinde, Allgemeinzustand). Sie genehmigen den Versand \u2013 wir versenden niemals blind.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Schnelle Lieferung<\/span><\/strong><span class=\"\">\u00a0\u2013 5\u20138 Werktage Lieferzeit ab unserem Lager in Guangzhou.

Anwendungen<\/span><\/h3>\n<p class=\"ds-markdown-paragraph\"><span class=\"\">The remanufactured Hitachi 9184686 main pump is ideal for ZAX450\u20116 and 40\u2011ton class excavators used in high\u2011production environments:<\/span><\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Large\u2011scale mining &amp; quarrying<\/span><\/strong><span class=\"\">\u00a0\u2013 40\u2011ton excavators are the backbone of many open\u2011pit mines and aggregate quarries. A pump with restored volumetric efficiency delivers full power all day \u2013 faster loading cycles, better fuel economy, and no mid\u2011shift power fade.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Heavy civil construction<\/span><\/strong><span class=\"\">\u00a0\u2013 Dam building, highway excavation, tunnel portal work, and large\u2011scale earthmoving demand consistent hydraulic power. A remanufactured pump gives you predictable performance at a cost that makes sense for older machines.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Demolition &amp; scrap recycling<\/span><\/strong><span class=\"\">\u00a0\u2013 Shock loads and vibration accelerate pump wear. Our remanufacturing process replaces all bearings, seals, and wear plates, restoring the pump\u2018s ability to survive the most punishing conditions.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Material handling &amp; port operations<\/span><\/strong><span class=\"\">\u00a0\u2013 Loading logs, scrap metal, or aggregates requires smooth, responsive hydraulic control. A properly remanufactured pump with factory\u2011spec tolerances provides that control without the expense of a new unit.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Ger\u00e4tevermietungsflotte<\/span><\/strong><span class=\"\">\u00a0\u2013 Keeping 40\u2011ton excavators in rental service means minimising downtime. A remanufactured pump offers a predictable service life (3,000\u20135,000 hours) and allows you to budget for replacements without the shock of a new genuine price tag.<\/span><\/p>\n<\/li>\n<\/ul>\n<h3><span class=\"\">3.

We know that a main pump failure on a ZAX450\u20116 stops production completely. Our remanufacturing process is not a \u201cclean and reseal\u201d \u2013 it is a factory\u2011grade restoration.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Our 6\u2011step remanufacturing process:<\/span><\/strong><\/p>\n<ol start=\"1\">\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Complete disassembly<\/span><\/strong><span class=\"\">\u00a0\u2013 The pump is stripped down to individual components: cylinder block, piston assemblies, valve plate, swashplate, bearings, shaft, housing, and control valves.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Cleaning &amp; crack inspection<\/span><\/strong><span class=\"\">\u00a0\u2013 All parts are thoroughly cleaned and inspected for cracks or damage using dye penetrant testing on critical castings. Irreparable parts are scrapped.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Wear component replacement<\/span><\/strong><span class=\"\">\u00a0\u2013 All seals, O\u2011rings, bearings, and gaskets are replaced with new, high\u2011quality parts. The cylinder block and valve plate are re\u2011ground to restore flatness. Piston assemblies are matched as a set and replaced if worn. The swashplate surface is reconditioned or replaced.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pr\u00e4zisionswiederaufbau<\/span><\/strong><span class=\"\">\u00a0\u2013 Components are reassembled using OEM torque specifications.

We verify operating pressure (up to 35 MPa), flow rate (400+ L\/min total), case drain leakage (must be within spec), and power control response. A test report is available upon request.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Final quality check &amp; packaging<\/span><\/strong><span class=\"\">\u00a0\u2013 The pump is painted, fitted with protective port caps, and packed in a heavy\u2011duty wooden case for export.<\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Why our remanufactured pump outperforms cheaper \u201crebuilt\u201d units:<\/span><\/strong><\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">New bearings and seals<\/span><\/strong><span class=\"\">\u00a0\u2013 Many budget rebuilders reuse old bearings to save cost. We do not. All rotating components get new bearings \u2013 the single most important factor for pump longevity.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pr\u00e4zisionsgeschliffene Verschlei\u00dffl\u00e4chen<\/span><\/strong><span class=\"\">\u00a0\u2013 The cylinder block and valve plate are re\u2011ground to restore flatness. A lapped surface is essential for low internal leakage. Without it, the pump will overheat and lose power within weeks.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Full test report<\/span><\/strong><span class=\"\">\u00a0\u2013 Upon request, we provide a test report showing pressure, flow, case drain, and temperature measurements.
