Core Product Advantages
1:1 Drop-in Full InterchangeabilityIdentical installation dimensions, spline specifications and oil port layout as the original A11VO95 pump. Direct plug-and-play installation without any mechanical alteration, greatly reducing equipment downtime and spare part procurement expenses.
Heavy-Duty Wear-Resistant StructureForged high-strength alloy cylinder block, ultra-precision machined piston slipper pairs, reinforced heavy-load bearings and high-performance wear-resistant sealing kits. Stable long-term operation under continuous high-pressure heavy loads, featuring low internal leakage and extended service lifespan.
Strict Global Standard Quality ControlAll pumps are manufactured in strict accordance with ISO9001:2015 quality management system and fully pass SGS certification. Every finished pump undergoes independent pressure resistance testing, full flow calibration and long-cycle durability inspection before delivery to guarantee consistent, stable and reliable performance.
Modular Multiple Control Options for Wide ApplicationsDiversified modular control configurations cover full flow, pressure and power regulation demands of medium & heavy construction machinery, perfectly matching small concrete pump trucks, underground mining loaders, roadheaders, wet shotcrete machines and compact road rollers.
Factory Competitive Strengths
Direct Source Manufacturer: Independent in-house R&D, production and professional testing workshops, no intermediate distributors to add markup
Adequate Ready Stock & Ultra-Short Lead Time: Mass inventory of all standard control models enables fast global sea & air shipment
Highly Competitive Factory Pricing: Manufacturer produces and sells products directly
Comprehensive Global After-Sales Support: 12-month worldwide warranty and one-stop professional technical consultation & troubleshooting service
Typical Application Scenarios
Small concrete pump trucks, underground mining loaders, roadheaders, wet shotcrete machines, compact road rollers and all medium-heavy mobile construction machinery equipped with open-circuit hydraulic systems.
