I. Product Specifications (SPECIFICATION)

II. Product Details (PRODUCT DETAILS)

1. 70MPa High Pressure + Steel Structure, Durable & Leak-Proof:The reservoir and pump body frame are made of high-strength low-carbon steel with a tensile strength of 375MPa. Under 70MPa high-pressure working condition, the reservoir deformation is ≤0.3mm, with no risk of cracking or leakage; the inner wall of the cylinder is chrome-plated for wear resistance, with a surface finish of Ra0.4μm. Combined with a 6.8mm high-precision pump core, the hydraulic oil leakage is ≤0.5ml/h. Compared with ordinary cast iron pumps, the sealing performance is increased by 80%. Even when used for a long time in oily and dusty engineering sites, it can maintain stable performance, with a service life of more than 10 years.
2. 850/170ml/min Dual Flow, Dual Efficiency in Start-Up & Operation:The output flow reaches 850ml/min under no-load, which can quickly fill hydraulic tools with oil — when driving a 20-ton hydraulic jack, it can complete the start-up from "no pressure" to "working height" within 25 seconds, saving 60% of preparation time compared with ordinary pumps; when loaded, it automatically switches to a stable flow of 170ml/min, with pressure fluctuation ≤1.5%, ensuring continuous power for hydraulic wrenches to disassemble heavy bolts above M40 and breakers to crush concrete, avoiding operation jams caused by unstable flow, and balancing "fast response" and "stable operation".
3. 3200ml Large Reservoir, Long Endurance Without Interruption:Equipped with a 3200ml extra-large capacity steel reservoir, which is more than 2.5 times that of ordinary hydraulic pumps (about 800-1200ml), it can meet the oil supply demand for 12 hours of continuous operation — during engineering emergency repair, there is no need to stop and refuel frequently; during multi-station turnover in industrial workshops, one oil injection can cover 3-4 workstations, greatly reducing non-operation time, adapting to "high-intensity and long-term" operation scenarios, and solving the pain point of "short endurance and frequent refueling" of traditional pumps.
4. Air-Driven + Reducer Ports, Labor-Saving & Compatible:Adopting air-driven mode, it can run by connecting an air compressor of 0.28-0.86MPa, no manual handle pressing is needed, and it can be easily operated by one person, saving 90% of labor cost compared with manual pumps; the input and output ports adopt NPT reducer threads (1/4" in + 3/8" out), the input is compatible with most small air compressor connectors, and the output is compatible with large-diameter high-pressure tools, which can be connected without additional adapters, with compatibility over 98%. One pump can match multiple tools such as hydraulic wrenches, jacks, and breakers, reducing equipment purchase costs.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Heavy Equipment Emergency Repair at Engineering Sites:During the maintenance of medium excavators, loaders and other equipment in mining and construction projects, use this pump to drive hydraulic wrenches to disassemble and assemble heavy chassis bolts. The 70MPa high pressure ensures quick bolt disassembly and assembly; the 3200ml reservoir supports 8 hours of continuous operation without refueling in the middle; the steel structure is impact-resistant, and even bumps in sites with many gravels do not affect performance, adapting to the engineering emergency repair needs of "high intensity and harsh environment".
2. Chassis Overhaul of Vehicles in Heavy Maintenance Plants:When maintaining the chassis of heavy trucks and engineering vehicles (such as semi-trailers and bulldozers), drive the hydraulic jack to lift vehicles within 30 tons, and the 70MPa high pressure ensures stable support; air-driven operation requires no manual labor, allowing technicians to focus on maintenance operations; the 850ml/min no-load flow quickly starts the jack, and the 170ml/min loaded flow keeps the vehicle stable, adapting to the maintenance plant's needs of "efficient overhaul and safe operation" and improving chassis maintenance efficiency.
3. Heavy Component Assembly in Industrial Workshops:When assembling large gearboxes, engine blocks and other heavy components in automobile and machinery manufacturing workshops, use this pump to drive hydraulic presses. The 0.28-0.86MPa pressure adjustment adapts to the pressing needs of different components; the 3200ml reservoir meets the daily assembly oil supply, no frequent oil injection is needed; the steel reservoir is resistant to oil pollution and corrosion, adapting to long-term use in oily workshop environments, ensuring the pressing precision error ≤0.1mm and improving the assembly qualification rate.
4. Outdoor Power/Infrastructure Emergency Repair:When the power department repairs high-voltage towers and infrastructure teams maintain bridge supports, use this pump to drive hydraulic tools to disassemble and assemble large fasteners. The 850ml/min fast start-up shortens the emergency repair preparation time; the 340220215mm packing size can be easily placed in the emergency repair vehicle, and air-driven operation requires no external power supply; the steel structure is moisture-resistant, and there is no rust risk even in rainy outdoor operations, adapting to the emergency repair scenario of "no electricity outdoors and complex environment".
