Genuine replacement part 2418182A is a pump cylinder that serves as the main housing for the piston in the fluid section, providing a precision bore for pressurizing material. A worn, scored, or damaged pump cylinder can cause pressure loss, poor spray performance, and premature seal failure. Replacing with this genuine pump cylinder restores pumping efficiency and ensures reliable operation on compatible Impact X units.

The 2418182A Pump Cylinder is a precision-machined component that houses the piston within the fluid section. On Impact X 410 and 440 units, this cylinder provides a smooth, accurate bore that allows the piston to create the high pressure needed for consistent material delivery and spray performance.
A worn, scored, or damaged pump cylinder can lead to pressure loss, erratic output, rapid seal wear, and reduced spraying efficiency. Replacing the cylinder with a genuine 2418182A restores proper pump geometry, ensures reliable pressure buildup, and extends the life of the fluid section.
| Piston housing | Provides a precision bore for the piston to move and pressurize material |
|---|---|
| Pressure generation | Works with the piston to create high pressure for spraying |
| Sealing surface | Offers a smooth surface for piston seals to maintain efficiency |
| Pressure loss | Unable to reach or maintain operating pressure |
|---|---|
| Visible wear/damage | Scoring, pitting, corrosion, or out-of-round cylinder bore |
| Erratic output | Pressure surges or uneven spray pattern |
| Frequent seal failure | Piston seals wear quickly due to rough cylinder surface |
Part 2418182A is compatible with the following Impact X models. Always confirm fitment using the correct parts diagram for your exact machine.
| Brand / Model | Component |
|---|---|

| Impact X: 440 | Pump Cylinder (2418182A) |
When replacing the pump cylinder, these related components are often inspected and replaced at the same time:
Inspect for wear or damage; a new piston ensures proper fit in the new cylinder.
Always install new seals with a new cylinder to ensure proper sealing and prevent leaks.
Worn valves can affect pump performance; inspect and replace if necessary.
