Fitur &amp; Manfaat Utama<\/span><\/h3>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Dibuat ulang secara profesional sesuai spesifikasi OEM<\/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=\"\">Sistem kontrol daya terintegrasi (load-sensing)<\/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=\"\">Alternatif hemat biaya untuk unit asli baru<\/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=\"\">Pengganti baut langsung<\/span><\/strong><span class=\"\">\u00a0\u2013 Mounting flange, drive shaft spline, and hydraulic port configurations are restored to original Hitachi specifications. No modifications, no adapters, no fabrication \u2013 your mechanic unbolts the old pump and bolts this one in.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Verifikasi visual pra-pengiriman<\/span><\/strong><span class=\"\">\u00a0\u2013 Sebelum pengemasan, kami mengirimkan foto resolusi tinggi terperinci dari unit buatan ulang yang sebenarnya (flensa pemasangan, spline, ulir port, kondisi umum). Anda menyetujui pengiriman \u2013 kami tidak pernah mengirim secara buta.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pengiriman cepat<\/span><\/strong><span class=\"\">\u00a0\u2013 Waktu tunggu 5\u20138 hari kerja dari gudang Guangzhou kami. Kapasitas pasokan bulanan 300 unit, tersedia untuk pesanan satuan atau grosir.<\/span><\/p>\n<\/li>\n<\/ul>\n<h3><span class=\"\">2. Aplikasi<\/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=\"\">Armada sewa peralatan<\/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=\"\">Proses rekondisi 6 langkah kami:<\/span><\/strong><\/p>\n<ol start=\"1\">\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pembongkaran total<\/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=\"\">Pembersihan &amp; inspeksi retak<\/span><\/strong><span class=\"\">\u00a0\u2013 All parts are thoroughly cleaned and inspected for cracks or damage using dye penetrant testing on critical castings.
