Both listed part numbers share identical external mounting structure and internal hydraulic configuration, enabling mutual replacement across 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 is engineered to match the original hydraulic system design for VIO40 / VIO50 / VIO55 series platform
Rated continuous working pressure follows factory system specifications, with preset maximum relief pressure to deliver reliable overload protection
Operating rotation speed range is precisely calibrated to match the rated speed of the original engine fitted 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 adopt quenched alloy steel to boost wear resistance and extend total service lifespan
3. Internal Structure & Functional Introduction
Main piston pump generates 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 proper fitment inside the limited hydraulic compartment of mid-size mini excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, allowing 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 kept 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 six machine variants, streamlining inventory planning for spare part suppliers and repair service shops
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 B0600-16023 and B0600-16017 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 all six listed VIO series models?A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for VIO40-2, VIO40-3, VIO50-2, VIO50-3, VIO55-2 and VIO55-3 without extra adjustment or tuning work.
Q: Are separate 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.
