The 0278337 pusher body is a mechanical component used within the pump or drive mechanism of compatible sprayer systems. It is specifically designed for use with SprayTech AirCoat and SprayTech ED655 Plus models. Its primary function is to transmit force from one part of the system to another. It may act as a follower that pushes against a diaphragm, a driver that actuates a piston, or a component that moves fluid by displacement. The pusher body is typically a precision-machined part made from durable materials such as metal or engineered plastic to withstand the forces and wear of continuous operation. It is designed to move smoothly within a cylinder or along a guide, transferring motion and pressure effectively. Over time, pusher bodies can become worn, scored, or damaged due to friction, contamination, or fatigue. A worn or damaged pusher body can lead to loss of pressure, erratic operation, reduced fluid output, or complete failure of the pumping mechanism. Symptoms of a faulty pusher body include the sprayer failing to build or maintain pressure, unusual noises from the pump area, visible wear on the component, or fluid leakage from the area it operates in. Replacing a worn or damaged pusher body with this genuine part restores proper force transmission and reliable mechanical function. This ensures that the pump operates efficiently and delivers consistent performance. When replacing, it is important to inspect related components such as seals, guides, or cylinders for wear.
| Force transmission | Transfers mechanical force |
|---|---|
| Motion transfer | Converts or transmits motion |
| Fluid displacement | May act as a pumping element |
| Pressure loss | Unable to build or maintain pressure |
|---|---|
| Erratic operation | Inconsistent pump performance |
| Unusual noise | Grinding or knocking from pump |
| Visible wear | Scoring, pitting, or damage |
