The Graco 249122 Displacement Pump restores prime, pressure, and spray quality on GMAX II 7900 and compatible TexSpray units. If you need only seals/packings, use the dedicated repair/packing kit (commonly 249123) instead of replacing the entire pump.
Commonly Confused SKUs
| SKU | What It Is | When To Choose |
|---|---|---|
| 249122 | Displacement Pump (Complete Assembly) for GMAX II 7900 / TexSpray 7900 HD | Choose when the pump body/rod/cylinder are worn or damaged, or when a full assembly swap is faster for uptime. |
| 249123 | Pump Repair / Packing Kit for servicing the 249122 pump | Choose when the pump body is healthy and you only need to replace packings/seals to fix leakage or pressure loss. |
Key Benefits
- Factory-spec fit for listed GMAX II 7900 models and TexSpray 7900 HD.
- Restores consistent pressure and smooth spray pattern for high-output jobs.
- Direct-swap assembly minimizes downtime compared to full teardown rebuilds.
Fit & Verification Tips
- Confirm your exact sprayer model (e.g., 248700, 248701, 248702, 248703, 248953, 258735).
- If your intention is a seal/packing refresh, order the repair kit (commonly 249123) instead of this full pump.
- Use only genuine Graco components to maintain pressure ratings and longevity.
