Inside the 287946 Pump Breakdown
Every 287946 wet-end ships pressure-tested, pre-oiled and ready for a 60-second ProConnect swap:
- Piston Rod — Chromex steel with Vortex grooves spins abrasive solids away from packings.
- Cylinder & Sleeve — Hardened stainless rated for continuous 3 300 PSI duty.
- Intake/Outlet Check — Tungsten-carbide seat and chrome-steel ball handle hot solvents and high-viscosity muds.

Cross-Platform Compatibility
Running multiple rigs? Many consumables overlap with other popular Graco models, simplifying truck-stock:

Pro Tips for Triple-Shift Reliability
- Flush Hot & Fast — Run FastFlush™ at full 3 300 PSI for 45 s; low-pressure rinses leave pigment that chips seats.
- Log Packings Early — Replace V-packs every 150 000 cycles (≈700 gal). BlueLink pings your phone before wear shows.
- Keep a Drop-In Pump — ProConnect lets you swap the 287946 in 60 s—cheaper than overnight freight on a seized rod.
- Seal the Electronics — Replace the control-box gasket whenever you open the lid; moisture is board-killer #1.
- Color-Code Storage — Orange = wet-end kits, Blue = electronics, Green = hardware. Crews find graco filters and strainers fast, even on night shifts.

Rapid-Fire Q & A
Will a Mark X Premium pump fit my Mark VII Max? No—the Mark VII uses pump 24M416; stroke length differs by 18 %.
Can the 287946 handle elastomeric block filler? Yes—pair a ½″ hose with a 0.039″ RAC X WideRAC tip and keep pressure above 2 700 PSI for a uniform pattern.
Is a 5 kW generator enough? Graco recommends 5 kW continuous (6 kW surge) for 120 V units; 240 V versions need 7 kW for full flow.
