Our dump truck hydraulic oil tanks are engineered to exceed strict standards. They feature exceptional internal cleanliness (<50 µm particles) and pass rigorous leak tests (≥50 kPa), preventing contamination and failure. Built with materials like aluminum alloy, stainless steel, or polymer, and available in 80-250L capacities, each tank includes a high-flow return filter (<25 µm, >200 L/min) for critical component protection.
we can customise, including color, size and logo for a perfect fit and brand alignment. Compared to standard options, our hydraulic oil tanks deliver superior contamination control, robust construction, and flexible custom solutions that reduce installation hassle and enhance system longevity. This means cleaner oil, fewer breakdowns, and a reservoir that matches your specific truck and operational needs.Contact us to Find your ideal hydraulic oil reservoir for your dump truck
Dump truck hydraulic oil tank (hydraulic oil reservoir) is the foundation of a stable hydraulic system—storing, cooling, and conditioning oil to protect pumps, valves, and cylinders. FLYBY provides reliable hydraulic oil tanks for dump trucks engineered for clean oil management, leak resistance, and easy installation, with flexible customization for different vehicle layouts and operating conditions.
Contamination is one of the most common causes of hydraulic failure. FLYBY tanks are built to strict cleanliness requirements with internal cleanliness <50 μm particles, helping reduce wear and extending the service life of critical parts. Each tank integrates a high-flow return filter designed for <25 μm filtration with >200 L/min flow capacity, supporting effective filtration without restricting return flow—especially important for high-cycle tipping operations.
To minimize oil loss and downtime, every tank is verified through rigorous leak testing ≥50 kPa. This pressure-based inspection helps ensure tight sealing and consistent quality, delivering a durable reservoir that performs reliably in demanding environments such as construction sites, mining haul roads, and continuous fleet operations.
Different applications require different tank materials and weight targets. FLYBY offers hydraulic reservoirs made from aluminum alloy, stainless steel / metal, and polymer (plastic)—allowing you to balance lightweight design, impact resistance, and corrosion protection. This material flexibility supports both new builds and retrofit projects where space and payload considerations matter.
FLYBY hydraulic oil tanks are available in 80–250L capacities, enabling proper matching for various dump truck sizes, duty cycles, and hydraulic circuit demands. A correctly sized reservoir helps maintain oil temperature control and reduces aeration risk, improving overall system stability during frequent lifting and lowering.
Every truck configuration is different. FLYBY provides custom hydraulic oil tank services—including color, size, and logo—to ensure a clean fit, consistent branding, and simpler mounting integration. This helps shorten installation time and supports fast replacement cycles when vehicles must return to work quickly. With stable production capability, we support fast delivery and global supply requirements for ongoing maintenance and fleet expansion.
Common choices include metal reservoirs (e.g., IT-R, YXCFY-57-02, YX8-80L), lightweight aluminum designs (e.g., JH-100b3-BL, CFY-51, YXCFY-57-1), and polymer solutions (e.g., JT-QZ-110L), covering multiple installation preferences.
Q1: What size hydraulic oil tank does a dump truck need (80L, 110L, 250L)?
Tank size depends on pump flow, cylinder volume, duty cycle, and heat load. Larger capacity improves cooling and reduces aeration during frequent tipping.
Q2: Why is internal cleanliness (<50 μm) important for a hydraulic oil reservoir?
Cleaner internal surfaces reduce initial contamination, protecting pumps and valves and lowering the chance of premature wear and system failure.
Q3: What does a ≥50 kPa leak test mean for a hydraulic oil tank?
It confirms sealing integrity under pressure, helping prevent oil seepage, air ingress, and downtime caused by leaks.
Q4: Why use a high-flow return filter (<25 μm, >200 L/min)?
It captures fine particles while maintaining strong flow, supporting stable return circulation without excessive back pressure.
Q5: Can you customize a hydraulic oil tank for my truck?
Yes—FLYBY can customize size, color, and logo to match mounting space and brand requirements.
