Outfitted with an optimized dual-stage piston mechanism, this manual power device delivers a massive high-flow displacement under lower pressures to minimize unproductive stroke cycles, transitioning instantly into a rigid 10,000 psi maximum high-pressure mode when meeting full motor load resistance. The structural frame integrates a custom 55 cubic inch composite reservoir with an ergonomic fiberglass handle lever to completely reduce user fatigue across extended tracking tasks.\n        \u003c\/p\u003e\n\n        \u003cdiv style=\"background: #fdfdfd; border: 2px solid #eee; border-radius: 12px; padding: 25px; border-left: 10px solid #FFCC00; margin-top: 20px;\"\u003e\n            \u003ch3 style=\"margin-top: 0; font-size: 16px; color: #222;\"\u003e📋 Critical Application Check\u003c\/h3\u003e\n            \u003cul style=\"font-size: 14px; color: #555; padding-left: 20px;\"\u003e\n                \u003cli\u003e\n\u003cstrong\u003eIndustry:\u003c\/strong\u003e Field On-site Mobile Construction Repair, Electric Line Cable Crimping, Industrial Flange Splitting Blocks, Laboratory Material Compression Rigs, Plant Machine Leveling Jacks.\u003c\/li\u003e\n                \u003cli\u003e\n\u003cstrong\u003eTwo-Speed Efficiency Optimization:\u003c\/strong\u003e Engineered dual-piston logic boosts tracking speed during empty approach spans, optimizing job safety parameters while speeding overall factory turnaround times.\u003c\/li\u003e\n                \u003cli\u003e\n\u003cstrong\u003eRugged Composite Longevity:\u003c\/strong\u003e High-resistance molded shell protects the internal fluid store against harsh environment dynamic drops, extreme weather scaling, and onsite welding spatters.\u003c\/li\u003e\n            \u003c\/ul\u003e\n\n            \u003ch4 style=\"font-size: 14px; color: #222; margin-top: 20px; font-weight: 800;\"\u003eEnerpac Manual Pump Systems Integration:\u003c\/h4\u003e\n            \u003cul style=\"font-size: 14px; color: #555; padding-left: 20px;\"\u003e\n                \u003cli\u003eP-Series Hydraulic Hand Pumps: \n                    \u003ca href=\"\/zh\/collections\/enerpac\" style=\"color: #222222; text-decoration: underline; font-weight: 700;\"\u003eEnerpac Manual Hand Pump Array\u003c\/a\u003e\n                \u003c\/li\u003e\n                \u003cli\u003ePremium High-Pressure Networks: \n                    \u003ca href=\"\/zh\/collections\/enerpac\" style=\"color: #222222; text-decoration: underline; font-weight: 700;\"\u003eEnerpac Heavy Lifting Hydraulic Systems\u003c\/a\u003e\n                \u003c\/li\u003e\n            \u003c\/ul\u003e\n        \u003c\/div\u003e\n    \u003c\/div\u003e\n\u003c\/div\u003e","brand":"YingZhou Automatization","offers":[{"title":"P391","offer_id":52730609041711,"sku":"P391","price":321.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/9473\/5919\/files\/Enerpac-P391-Lightweight-Hydraulic-Hand-Pump-Single-Speed-10000-psi-55-in3-Oil-Capacity.jpg?v=1771842640","url":"https:\/\/szyingzhou.com\/zh\/products\/enerpac-p391-two-speed-lightweight-hydraulic-hand-pump","provider":"YingZhou Automatization","version":"1.0","type":"link"}
