Unified mounting flange, input shaft spline and hydraulic port layout supports direct replacement across all three machine configurations
2. Core Technical Specifications
Structure type: Tandem dual variable displacement piston main pump integrated with built-in pilot charge gear pump
Displacement configuration is matched to factory hydraulic design requirements of the SV100 mid-size excavator platform
Rated continuous working pressure adheres to original system settings, with preset maximum relief pressure for overload protection
Operating rotation speed range is precisely calibrated to match rated output of the original engine equipped on these excavator units
Mounting hole layout, shaft dimension and oil port orientation strictly follow OEM dimensional drawings
Pump housing is constructed from ductile iron; internal pistons, valve plates and friction components adopt quenched alloy steel to improve wear resistance and extend overall service life
3. Internal Structure & Functional Introduction
Dual main piston pumps supply high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing working motions
Integrated pilot gear pump provides stable pressurized oil supply for pilot control circuits and system hydraulic oil replenishment
Built-in power matching regulators adjust total pump flow output automatically according to load fluctuations, preventing engine stall under heavy digging working conditions
Optimized compact tandem layout makes proper fitment inside the designated hydraulic compartment of SV100 series excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, enabling plug-and-play installation without modification to hydraulic pipelines or chassis mounting structure
Every finished pump undergoes 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
Single OEM part number covers three machine variants, simplifying inventory management for spare part dealers 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 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: Does this pump work for SV100-2A, SV100-2B and SV100-2A-2PB directly?
A: Yes, consistent mounting dimensions and factory-calibrated hydraulic parameters allow direct bolt-on installation for all three listed models with no extra adjustment required.
Q: What is the relationship between K7SP36, K7V28 and part number 172B12-73100?
A: K7SP36 and K7V28 are the internal model codes for the two sections of this tandem pump assembly, while 172B12-73100 is the official OEM part number assigned by Yanmar for the complete pump unit.
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.
