Rexroth A10VO18 Main Hydraulic Pump for Wacker Neuson EZ17 EZ17E Mini Excavator Repair Parts
1. OEM Part Number & Machine Compatibility
- Original pump model: Rexroth A10VO18 variable displacement axial piston pump
- Core reference part number: R902569211
- Fully compatible mini excavator models: Wacker Neuson EZ17, EZ17E (electric zero-tail excavator variant)
- Standard mounting flange, input shaft spline and hydraulic port layout enables direct bolt-on replacement for both conventional engine-driven EZ17 and battery-powered EZ17E models
2. Core Technical Specifiions
- Structure type: Swashplate variable axial piston pump with integrated control valve assembly
- Max displacement: 18 cm³/rev, precisely calibrated to match original hydraulic system design of EZ17 series platform
- Rated continuous working pressure: 280 bar; peak pressure up to 350 bar for reliable overload protection
- Maximum rated rotation speed: 3300 rpm, matching designated operating speed range of machine power source
- Mounting hole arrangement, shaft specifiion and port orientation strictly comply with original OEM dimensional standards
- Pump housing constructed from high-strength ductile iron; internal pistons, valve plates and friction components adopt quenched wear-resistant alloy steel to extend operational lifespan
3. Internal Structure & Functional Introduction
- Piston pump delivers high-pressure hydraulic oil to actuate boom, arm, bucket, travel and swing operational movements
- Built-in pressure regulator automatically modulates pump flow output responding to load fluctuations, preventing power overload and unnecessary energy consumption
- Compact body design fits neatly inside the narrow hydraulic compartment of compact zero-tail mini excavators
- Optimized internal flow path reduces pressure loss and operating noise, maintaining stable performance during continuous digging work
4. Product Advantages
- Exact 1:1 OEM outer casting dimensions, supporting plug-and-play installation with no modifiion to hydraulic pipelines or mounting structure
- Every finished pump undergoes comprehensive hydraulic bench inspection covering pressure stability, flow consistency and internal leakage testing prior to shipment
- Complete maintenance spare parts are held in stock, including overhaul seal kits, piston assemblies, swash plates and valve plates for separate component replacement during repair work
- Single pump model fits both fuel-powered EZ17 and electric EZ17E versions, simplifying inventory planning for spare part suppliers and repair service workshops
5. Packaging & Global Delivery Details
- Input shaft and all hydraulic ports are coated with anti-rust grease and sealed with protective dust plugs
- The entire pump is wrapped with moisture-proof plastic film and secured inside export-grade solid wooden crate to prevent collision and moisture damage during long-distance sea or air transportation
- In-stock items can be dispatched within 3 to 5 working days after order confirmation
- Multiple global shipping solutions are available: international air express, sea LCL/FCL bulk shipment and overland truck transportation for global customers
6. FAQ
- Q: Can this A10VO18 pump fit both EZ17 and electric EZ17E directly?
A: Yes, unified mounting dimensions and factory-calibrated hydraulic parameters support direct installation for both models with no extra adjustment or modifiion required.
- Q: What is R902569211 in relation to A10VO18?
A: A10VO18 is the official Rexroth pump model designation, while R902569211 is the unique material number assigned by Rexroth for this complete pump assembly.
- Q: Are individual repair spare parts available for this hydraulic pump?
A: Corresponding full overhaul seal kits, piston shoe assemblies, valve plates, swash plates and internal wear components are all available for partial overhaul and individual component replacement work.
