Product Description
172175-73100 172175-73200 PVD-1B-32P Main Hydraulic Pump for Yanmar VIO30 VIO33U VIO30-1 VIO30-2 VIO30-3 Mini Excavator (Point-by-Point Layout)
1. OEM Part Number & Machine Compatibility
  • Original pump model: Nachi PVD-1B-32P variable displacement piston pump assembly
  • Yanmar OEM part numbers: 172175-73100, 172175-73200
  • Fully compatible mini excavator models: Yanmar VIO30, VIO33U, VIO30-1, VIO30-2, VIO30-3
  • The two part numbers share identical external mounting structure and internal hydraulic configuration, allowing mutual replacement for all applicable machine versions
2. Core Technical Specifications
  • Structure type: Integrated assembly of variable axial piston main pump and built-in pilot charge gear pump
  • Main pump displacement matches the original hydraulic design for VIO30 series compact excavator platform
  • Rated continuous working pressure complies with factory system settings, with preset maximum relief pressure for system overload protection
  • Operating rotation speed range is calibrated to match the original engine rated speed of these small excavator units
  • Mounting bolt layout, input shaft spline dimension and hydraulic port orientation strictly follow OEM dimensional standards
  • Pump housing is made of ductile iron; internal pistons, valve plates and wearing components adopt quenched alloy steel to strengthen wear resistance and extend service life
3. Internal Structure & Functional Introduction
  • Main piston pump generates high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing operational movements
  • Integrated pilot gear pump provides stable pressure oil supply for pilot control circuits and system oil replenishment
  • Built-in power adjustment regulator automatically changes pump flow output according to load fluctuations, avoiding engine stall under heavy digging working conditions
  • Compact integrated structure saves installation space inside the limited hydraulic compartment of ultra-small mini excavators
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 completes comprehensive hydraulic bench inspection including 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
  • Dual interchangeable part numbers fit five machine models, simplifying inventory arrangement for spare part suppliers and repair 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 whole pump is wrapped with moisture-proof plastic film and fixed inside export-grade solid wooden crate to prevent collision and damp 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 172175-73100 and 172175-73200 interchangeable?
    A: Yes, both part numbers correspond to the same PVD-1B-32P pump assembly with identical installation size and internal parameters, suitable for cross installation on all listed Yanmar excavators.
  • Q: Does this pump fit all five listed Yanmar models directly?
    A: Yes, unified mounting dimensions and matched hydraulic tuning enable direct bolt-on installation for VIO30, VIO33U, VIO30-1, VIO30-2 and VIO30-3 without extra adjustment.
  • Q: Are individual repair spare parts available for this hydraulic pump?
    A: Matching full overhaul seal kits, piston shoe assemblies, valve plates, swash plates and independent pilot gear pump spare parts are all available for partial overhaul maintenance and component replacement.
