Product Description

172441-73100 172422-73101 PVD-1B-29BP-12G5-4614F Main Hydraulic Pump for Yanmar B25V B25V-1 B30V-1 Mini Excavator (Point-by-Point Layout)

1. OEM Part Number & Machine Compatibility

Original pump model: Nachi PVD-1B-29BP-12G5-4614F variable displacement piston pump
Yanmar OEM part numbers: 172441-73100, 172422-73101
Directly compatible mini excavator models: Yanmar B25V, B25V-1, B30V-1
Two listed OEM numbers are fully interchangeable, sharing identical mounting structure and internal hydraulic configuration for cross replacement

2. Core Technical Specifications

Structure type: Integrated assembly of variable axial piston main pump plus built-in pilot gear charge pump
Main pump displacement: 29 cc/rev
Rated continuous working pressure: 24.5 MPa; factory preset maximum relief pressure: 31.4 MPa
Operating rotation range perfectly calibrated to match the original engine speed setting of B25V and B30V-1 series machines
Input shaft spline, mounting flange hole layout and all hydraulic port positions strictly follow OEM dimensional specifications
Pump housing is manufactured from ductile iron; internal pistons, valve plates and friction components adopt quenched wear-resistant alloy steel for extended service life

3. Internal Structure & Functional Introduction

Main piston pump delivers high-pressure hydraulic oil to actuate boom, arm, bucket, travel and swing movements
Integrated pilot gear pump supplies consistent pressure oil for pilot control circuit and system makeup oil replenishment
Built-in power adjustment regulator automatically modulates pump output flow according to load fluctuations, preventing engine stall under heavy digging working conditions
Compact integrated design saves installation space inside the compact hydraulic compartment of small mini excavators

4. Product Advantages

Exact 1:1 OEM casting dimensions with matched bolt hole pattern and port layout, supporting plug-and-play replacement without hydraulic pipe or chassis modification
Each finished pump undergoes comprehensive hydraulic bench testing covering pressure stability, flow consistency and internal leakage inspection prior to delivery
Complete range of maintenance spare parts including overhaul seal kits, piston assemblies, swash plates and valve plates are available for separate component replacement during repair work
Dual interchangeable part numbers fit three machine variants, lowering inventory stocking pressure for dealers 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 secured inside export-grade solid wooden crate to avoid collision and moisture damage during long-distance sea or air transit
In-stock units can be arranged for shipment within 3 to 5 working days after order confirmation
Multiple global shipping solutions are supported: international air express, sea LCL/FCL bulk shipment and overland truck transportation for Southeast Asian customers

6. FAQ

Q: Are 172441-73100 and 172422-73101 mutually replaceable?
A: Yes, these two OEM part numbers correspond to the same Nachi PVD-1B-29BP-12G5-4614F pump structure, fully interchangeable for B25V, B25V-1 and B30V-1 installation.
Q: Can this pump be installed on all three listed Yanmar models directly?
A: Yes, unified mounting size and internal hydraulic calibration make it a direct replacement part for B25V, B25V-1 and B30V-1 without extra adjustment.
Q: Are separate repair components available for this hydraulic pump?
A: Matching overhaul seal kits, piston shoe assemblies, valve plates, swash plates and independent pilot gear pump spare parts are all in stock for partial overhaul maintenance.
