  • Kubota OEM part number: RG468-61110
  • Exact fit mini excavator model: Kubota KX030-4
  • Standard mounting flange, input shaft spline and hydraulic port layout enables direct bolt-on replacement for original pump assembly
2. Core Technical Specifications
  • Structure type: Dual variable axial piston main pump (first stage + second stage) integrated with built-in pilot charge gear pump
  • Displacement per main pump: 18 cm³/rev, matched to factory hydraulic system design of KX030-4 compact excavator platform
Second Stage Specified Parameters
  • Rated working pressure (second stage): 22.5 MPa
  • Maximum relief pressure (second stage): 24.5 MPa
  • Rated operating speed (second stage): 2300 rpm
  • Corresponding rated input power (second stage): 16.7 kW
  • Overall operating speed range precisely calibrated to match rated output of original engine equipped on KX030-4
  • Mounting bolt layout, input shaft dimension and oil port orientation strictly comply with Kubota OEM dimensional drawings
  • Pump housing constructed from high-strength ductile iron; internal pistons, valve plates and friction components adopt quenched wear-resistant alloy steel to extend total service lifespan
3. Internal Structure & Functional Introduction
  • Dual main piston pumps deliver high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing working motions
  • Integrated pilot gear pump supplies stable pressurized oil for pilot control circuits and system hydraulic oil replenishment
  • Built-in load-sensing power regulator automatically adjusts pump flow output according to real-time load fluctuation, preventing engine stall during heavy digging operations
  • Compact tandem integrated layout fits neatly inside the limited hydraulic compartment space of KX030-4 zero-tail mini excavator
4. Product Advantages
  • Exact 1:1 OEM outer casting dimensions, supporting plug-and-play installation without modification to hydraulic pipelines or chassis mounting structure
  • Every finished pump undergoes comprehensive hydraulic bench inspection covering pressure stability, flow consistency and internal leakage testing before 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 dedicated OEM part number designed exclusively for KX030-4, simplifying spare part ordering and inventory management for 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
