Here’s what you should know about the centrifugal impeller for the Kaishan KCOF8000 centrifugal air compressor:
1. Model Context
Kaishan KCOF8000 is a large-capacity centrifugal air compressor (likely in the 8000 m³/h or CFM range).
Impellers are precision components that convert kinetic energy into pressure — critical for compressor efficiency and reliability.
2. OEM vs. Aftermarket
Best source: Kaishan’s official parts distribution (Kaishan Compressor USA or Kaishan Global).
Aftermarket: Specialized manufacturers (e.g., CAGI-member shops) may produce replicas, but require exact drawings or a sample due to proprietary geometry.
3. Typical Impeller Specifications (KCOF Series)
| Parameter | Typical Value |
|---|---|
| Material | Forged aluminum alloy (6061-T6 / 7075) or stainless steel (17-4PH) |
| Diameter | ~300–500 mm (depends on stage) |
| Speed rating | 15,000–30,000 RPM |
| Balancing grade | ISO 1940 G1.0 or G2.5 |
| Hub taper | Specific to Kaishan shaft interface |
Verify exact data from your compressor’s nameplate or maintenance manual.
4. Where to Order / Request a Quote
Kaishan OEM
Kaishan Compressor USA: +1 (770) 888-3600
Kaishan Global: www.kaishan.com
Aftermarket / Replica
Need original part number (e.g., KCOF8000-IMP-01) or full dimensional inspection report.
Prepare to send worn impeller for scanning / reverse engineering.
5. Critical Maintenance Notes
Damage check – Pitting, cracks, or tip wear → immediate replacement.
Balance – After any repair (welding, coating) re-balancing is mandatory.
Lifting / handling – Use soft slings; never impact blades.
Installation torque – Follow Kaishan’s specified tightening pattern for the hub nut.
6. Next Steps
Locate the serial number of your KCOF8000.
Contact Kaishan parts support with that SN to get the correct impeller drawing and part number.
If discontinued, request cross‑reference or upgrade option (e.g., to a coated impeller for better erosion resistance).
