| Part Number: | 14650-VK500 | Product Name: | Brake Vacuum Pump |
| Car Model: | Nissan Navara | Engine Model: | Nissan D22 YD25 |
| Condition: | 100% Brand New | Size: | Standard |
| Weight: | Standard | Origin: | China Mainland |
| Main Market: | Middle East, Asia, Africa, South America, North America & Europe | ||
| Package: | Neutral Packing Or Make It As Requested | ||
| Material: | High-strength aluminum alloy & precision bearings | Cooling Type: | Engine coolant circulation |
| Installation: | Direct OEM replacement | Quality Standard: | OEM equivalent / ISO quality control |
| Feature | Benefit + Verification Signal |
|---|---|
| OE‑spec rotary vane design | Delivers ≥80 kPa vacuum at idle – ensures safe braking in D22 (known for heavy GVWR). Verified with digital manometer on running D22 YD25. |
| Premium carbon‑graphite vanes | Outlasts cheap plastic or aluminum vanes – 1,200‑hour accelerated wear test shows <0.4 mm length loss. |
| Precision CNC housing | Guarantees flat mounting flange (≤0.05 mm) to prevent oil seepage – CMM batch inspection. |
| High‑temperature oil seal | Prevents oil migration into vacuum system – tested at 1.2 bar oil pressure, 110°C, 48 hours, zero leakage. |
| Direct fit for D22 | No modification to outlet hose or mounting bracket – verified against Nissan workshop manual and 150+ installations. |
| 100% functional test | Each pump run on a test rig that simulates YD25 camshaft eccentric motion (500–4000 rpm) – vacuum curve recorded and noise checked ( <72 dB). |
| QC Item | Verification Method |
|---|---|
| Vacuum output profile | Automated bench with speed control – logged at 500, 1000, 2000, 3000, 4000 rpm |
| Static leak rate | Seal pump outlet, draw 85 kPa, measure drop over 60 seconds – <1.5 kPa allowed |
| Oil seal cross‑leak | Pressurize oil side with 1 bar compressed air, submerge vacuum side in water – zero bubbles |
| Housing porosity | Vacuum decay test on bare casting |
| Vane hardness | Shore D (if polymer) or Rockwell – certificate per batch |
| Drive slot concentricity | Alignment gauge relative to mounting flange – within 0.1 mm |
| Total functional test | Each pump runs at variable speed 500–4000 rpm for 3 minutes, monitored for vacuum stability, noise (≤72 dB), and temperature rise ( <20°C above ambient). |
