Uniform mounting flange, input shaft spline and hydraulic port layout enables direct replacement across all four machine iterations
2. Core Technical Specifications
Structure type: Integrated assembly of variable axial piston main pump and built-in pilot charge gear pump
Main pump displacement matches original hydraulic system design developed for the B37 excavator platform
Rated continuous working pressure follows factory system parameters, with preset maximum relief pressure to provide effective overload protection
Operating rotation speed range is precisely calibrated to align with rated output speed of the original engine equipped on these machines
Mounting hole arrangement, input shaft dimension and oil port orientation strictly comply with OEM dimensional drawings
Pump housing is made of ductile iron; internal pistons, valve plates and wear-resistant components adopt quenched alloy steel to improve durability and extend service life
3. Internal Structure & Functional Introduction
Main piston pump delivers high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing operational movements
Integrated pilot gear pump provides stable pressurized oil supply for pilot control circuits and system hydraulic oil replenishment
Built-in power adjustment regulator automatically alters pump flow output according to load changes, preventing engine stall under heavy digging working conditions
Compact integrated design optimizes space usage inside the confined hydraulic compartment of small excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, supporting plug-and-play installation without alterations to hydraulic pipelines or chassis mounting structure
Every finished pump undergoes full hydraulic bench inspection including pressure stability, flow consistency and internal leakage testing prior to 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
Single part number covers four model versions, simplifying inventory organization for spare part 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 fixed inside export-grade solid wooden crate to avoid 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 fit B37, B37-2, B37-2A and B37-2B directly? A: Yes, unified mounting dimensions and factory-matched hydraulic calibration allow direct bolt-on installation for all four listed models with no extra modification required.
Q: What does PVD-1B-32BP-11G5 represent? A: PVD-1B-32BP-11G5 is the original Nachi internal model code for this pump unit, while 172443-73100 is the exclusive OEM part number assigned by Yanmar for the complete assembly.
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.
