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.
