Description de produit

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.
