제품 설명
172B12-73100 K7SP36 K7V28 Main Hydraulic Pump for Yanmar SV100-2A SV100-2B SV100-2A-2PB Excavator (Point-by-Point Layout)
1. OEM Part Number & Machine Compatibility
  • Original pump model: Combined structure K7SP36 + K7V28 tandem variable piston pump assembly
  • Yanmar OEM part number: 172B12-73100
  • Fully compatible excavator models: Yanmar SV100-2A, SV100-2B, SV100-2A-2PB
  • 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.
