وصف المنتج
172B05-73100 172B05-73120 PSVD2-17E Main Hydraulic Pump for Yanmar VIO50U VIO57U VIO57-6A VIO57-6B Mini Excavator
1. OEM Part Number & Machine Compatibility
  • Original pump model: KYB PSVD2-17E variable displacement piston pump assembly
  • Yanmar OEM part numbers: 172B05-73100, 172B05-73120
  • Fully compatible mini excavator models: Yanmar VIO50U VIO57U VIO57-6A VIO57-6B
  • The two part numbers feature identical external mounting structure and internal hydraulic configuration, allowing mutual replacement across these machine generations
2. Core Technical Specifications
  • Structure type: Integrated assembly of dual variable axial piston main pump and built-in pilot charge gear pump
  • Single pump displacement: 17 cm³/rev, perfectly matched to factory ViPPS hydraulic system design for VIO57 series platform
  • Rated continuous working pressure: 24.5 MPa; preset maximum relief pressure provides reliable overload protection for the whole hydraulic circuit
  • Operating rotation speed range is precisely calibrated to match rated speed of the original engine equipped on these compact excavators
  • Mounting bolt layout, input shaft spline dimension and hydraulic port positioning strictly comply with OEM dimensional standards
  • Pump housing is constructed from ductile iron; internal pistons, valve plates and friction components use quenched alloy steel to enhance wear resistance and extend total service lifespan
3. Internal Structure & Functional Introduction
  • Dual main piston pumps generate high-pressure hydraulic oil to actuate boom, arm, bucket, travel and swing operational movements
  • Integrated pilot gear pump supplies steady pressurized oil for pilot control circuits and system makeup oil replenishment
  • Built-in power adjustment regulator automatically modulates pump flow output in response to load fluctuations, preventing engine stall during heavy digging operations
  • Compact integrated layout ensures neat installation inside the limited hydraulic compartment of VIO57 series mini excavators
4. Product Advantages
  • Exact 1:1 OEM outer casting dimensions, enabling plug-and-play installation with no modifications needed to hydraulic piping or chassis mounting structure
  • Every finished pump completes 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
  • Two interchangeable part numbers fit three model versions, streamlining 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 Southeast Asian markets
6. FAQ
  • Q: Are 172B05-73100 and 172B05-73120 interchangeable with each other? A: Yes, these two part numbers correspond to the same PSVD2-17E pump assembly with matching installation dimensions and internal hydraulic parameters, suitable for cross fitting on all listed Yanmar models.
  • Q: Can this pump mount directly on VIO50U VIO57U, VIO57-6A and VIO57-6B? A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for all three models with no extra adjustment or tuning work.
  • Q: Are individual repair components offered for this hydraulic pump? A: Corresponding full overhaul seal kits, piston shoe assemblies, valve plates, swash plates and standalone pilot gear pump spare parts are all available for partial overhaul and individual component replacement work.
