Гидронасос Nachi PVD-0B-18P-6G3-4191A для мини-экскаватора Komatsu PC15

PC15 Hydraulic Pump for Komatsu Excavator spare parts PVD‑0B‑18P‑6G3‑4191A Axial Piston pump Aftermarket

Product Brief

This aftermarket variable axial piston main pump with part number PVD‑0B‑18P‑6G3‑4191A acts as the core hydraulic power unit for Komatsu PC15 mini excavator. It converts engine rotational torque into adjustable high‑pressure hydraulic oil flow, providing steady driving force for bucket excavation, boom lifting, arm movement, upper‑structure slewing and crawler travelling. Komatsu PC15 mini excavators are widely used in narrow‑site construction, municipal pipeline laying, garden landscaping, indoor demolition and small‑scale earth‑moving tasks. These compact machines frequently work with frequent start‑stop and fluctuating loads, which gradually wear down internal pump assemblies over working hours. This replacement hydraulic pump is widely accepted by local repair workshops, mini‑excavator rental operators and global spare‑parts dealers for hydraulic system overhaul and replacement of worn‑out main pumps on Komatsu PC15 units.

Product Highlights

1. High‑precision aftermarket interchangeability. All mounting hole positions, spline parameters and oil port layout strictly follow original part drawing standards. Direct fit installation can be finished without extra cutting, drilling or gasket modification, effectively reducing on‑site working hours and cutting down equipment maintenance downtime.

2. Enhanced internal friction pair performance. Key wearing components are processed by quenching and ultra‑fine surface grinding. The pump delivers good resistance to cavitation, abrasion and internal leakage, adapting to tough job‑site conditions where hydraulic oil may contain tiny solid impurities.

3. Complete bench testing before goods delivery. Every finished pump goes through pressure‑holding test, flow performance detection, variable response calibration and noise inspection. It maintains stable pressure output and sensitive action feedback even under continuous cyclic variable‑load working conditions.

4. Cost‑effective aftermarket maintenance solution. Comparing with high‑priced original OEM pumps with long lead times, this aftermarket pump offers reliable practical performance at more competitive procurement cost, ideal for bulk purchasing of repair shops, rental fleet managers and spare‑parts distributors.

5. Standard export‑grade protective packaging. Precision contact surfaces are fully coated with anti‑rust grease. The pump is wrapped with shock‑absorbing cushion materials and packed inside thickened reinforced cartons, protecting components against collision damage, moisture and oxidation during long‑distance sea and land cross‑border transportation.

The full production procedure covers raw‑material incoming inspection, precision machining, heat‑treatment strengthening, dust‑free assembly and finished‑product hydraulic bench test. Random sampling durability simulation tests are performed for every production batch to verify real‑world operating stability. Our hydraulic spare parts are exported to Africa, Southeast Asia, Middle East and other overseas regions, building long‑term trusted partnerships with local construction machinery wholesalers and professional maintenance service providers.

Common Questions

Q: Can this PVD‑0B‑18P‑6G3‑4191A pump fit other Komatsu mini excavator models?
A: It is purpose‑built for Komatsu PC15. Mini excavator pumps vary greatly in displacement and spline specifications. Please double‑check your old part number and machine serial number before placing orders to avoid part mismatch.

Q: What typical machine faults can this hydraulic pump resolve?
A: It repairs common failures caused by internal component aging and wear: weak digging force, slow combined movements, hydraulic oil overheating, serious internal leakage, insufficient travel power and abnormal operating noise. It is highly suggested to replace hydraulic filter element and thoroughly clean the whole hydraulic circuit while installing the new pump.

Q: Do you support bulk discount and customized export packaging?
A: Yes, tiered preferential pricing is available for large‑volume orders. We support custom label printing and consolidated container loading service to help customers lower overall purchasing and logistics costs.

Q: What about after‑sales technical support?
A: Each finished pump has passed strict factory inspection. We provide remote professional technical guidance for installation and commissioning, assisting customers in solving common debugging problems after spare‑part replacement.
