Fitur &amp; Manfaat Utama<\/span><\/h3>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Professional remanufacturing to Hitachi OEM standards<\/span><\/strong><span class=\"\">\u00a0\u2013 This main hydraulic pump has been fully disassembled, cleaned, crack\u2011inspected, and rebuilt in our ISO\u2011certified facility in China. All worn components \u2013 cylinder block, piston assemblies, valve plate, swashplate, bearings, and 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 tandem axial piston design<\/span><\/strong><span class=\"\">\u00a0\u2013 The EX300\u20115 pump is a variable displacement double (tandem) axial piston pump combining two independent pumping sections in one housing. This design powers travel, swing, boom, arm, and bucket circuits independently, delivering smooth, coordinated multi\u2011function operation without internal flow loss \u2013 exactly as your machine performed when it left the factory.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Restored 30\u2011ton class hydraulic power<\/span><\/strong><span class=\"\">\u00a0\u2013 After remanufacturing, this pump delivers rated working pressure up to 34.3 MPa (\u22484,975 psi) and flow matched to the EX300\u20115\u2018s Isuzu B-6SD1T engine (169 kW at 1,900 rpm). With a hydraulic system relief valve pressure of 4,980 psi and operating weight of 31 metric tons, your excavator regains full digging force, fast cycle times, responsive swing, and powerful travel.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Kontrol daya load-sensing terintegrasi<\/span><\/strong><span class=\"\">\u00a0\u2013 Sistem kontrol daya pabrik (load-sensing) dibangun kembali sepenuhnya. Sistem ini secara terus-menerus menyesuaikan keluaran pompa dengan permintaan kerja aktual, mengurangi konsumsi bahan bakar, mencegah mesin mati mendadak akibat beban, dan memperpanjang umur seluruh sistem hidrolik. Pompa roda gigi pilot integral juga direkondisi sepenuhnya.<\/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 Hitachi main pump for a 30\u2011ton excavator is a major investment. Our remanufactured pump gives you the same fit, form, and function at a significantly lower price, without sacrificing reliability. Each pump is dyno\u2011tested 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 flanges, drive shaft splines, 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. Compatible variants include EX300\u20115, EX300LC\u20115, EX300LCLL\u20115, EX300LCLL\u20115M, EX330LC\u20115, EX350H\u20115, EX350K\u20115, EX370\u20115M, EX370HD\u20115 and EX385USR excavators.<\/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 We send you clear, high\u2011resolution photographs of the actual remanufactured unit (mounting flange, splines, port threads, castings, overall condition) before packing. You approve shipment \u2013 we never ship blind.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pengiriman cepat<\/span><\/strong><span class=\"\">\u00a0\u2013 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 EX300\u20115 main hydraulic pump is ideal for 30\u2011ton class excavators used in the most demanding job sites:<\/span><\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Konstruksi berat &amp; infrastruktur<\/span><\/strong><span class=\"\">\u00a0\u2013 Highway excavation, dam building, bridge footings, and large\u2011scale earthmoving projects. The restored tandem pump delivers simultaneous boom, arm, and travel power without internal leakage \u2013 no power fade, no sluggish response, even on long shifts. Urban development and road construction demand precise hydraulic control, and the load\u2011sensing system ensures smooth operation whether you\u2018re trenching near utility lines or working on highway shoulders.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Penambangan &amp; agregat<\/span><\/strong><span class=\"\">\u00a0\u2013 Loading trucks, stockpile management, and material handling in abrasive dust conditions are routine in granite, limestone and basalt operations. New bearings, seals, and wear plates ensure the pump survives where worn units fail. Consistent flow and pressure mean faster cycle times and lower fuel consumption, directly impacting your cost per ton.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Open\u2011pit mining support<\/span><\/strong><span class=\"\">\u00a0\u2013 Site cleanup, overburden removal, road maintenance, drainage works, and equipment pad grading. The pump\u2019s load\u2011sensing control reduces fuel burn during light\u2011duty cycles, saving money over thousands of operating hours. In mining environments where dust and vibration are extreme, our remanufactured pump with new seals and bearings provides the reliability you need to keep production moving.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Pembongkaran &amp; pemrosesan besi tua<\/span><\/strong><span class=\"\">\u00a0\u2013 Shock loads and vibration are routine in demolition yards and metal recycling facilities. Our remanufacturing process replaces all wear components, restoring the pump\u2018s ability to withstand harsh, unpredictable conditions. The integrated power control prevents engine stall when impact loads spike, maintaining consistent attachment power for shears, pulverizers, and hammers.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Kehutanan &amp; pembukaan lahan<\/span><\/strong><span class=\"\">\u00a0\u2013 Steep slopes, fallen timber, hidden obstacles, and remote locations demand hydraulic components you can trust. The integral power control prevents engine stall under sudden load spikes, maintaining consistent hydraulic power for saws, grapples, and mulchers. New seals prevent moisture ingress that is common in wet forestry environments.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Long\u2011reach &amp; specialized applications<\/span><\/strong><span class=\"\">\u00a0\u2013 EX300\u20115 Long Reach variants are used for river rehabilitation, coastal work, deep trench excavation, and batching plant responsibilities. The high-track models excel in quarry and mining environments with uneven terrain. A reliable main pump is essential for these specialized configurations where hydraulic demand varies constantly.<\/span><\/p>\n<\/li>\n<\/ul>\n<h3><span class=\"\">3. Mengapa Memilih<a href=\"https:\/\/www.hongtengdaparts.com\/id\/hubungi-kami\/\"> Bagian Hongtengda<\/a> \u2013 Quality You Can Trust<\/span><\/h3>\n<p class=\"ds-markdown-paragraph\"><span class=\"\">At Hongtengda Parts, we have been remanufacturing hydraulic pumps for Hitachi excavators since 2001. We know that a main pump failure on your EX300\u20115 stops your job site completely.
