Elite part 2369431 is a diaphragm assembly designed to transfer fluid in the pump of compatible Elite 3000 sprayers. This assembly includes the diaphragm, backing plate, and necessary hardware for a complete seal. Replacing a worn, torn, or damaged diaphragm assembly restores proper pump pressure and ensures reliable spraying performance.

The Elite 2369431 Diaphragm Assembly is an original-quality component engineered for the pump system of Elite 3000 sprayers. It serves as the flexible sealing element that creates suction and discharge cycles, enabling consistent fluid delivery at rated pressures. Manufactured to precise specifications, this assembly guarantees proper fit and long-lasting performance.
Continuous flexing and exposure to agricultural chemicals can cause diaphragm material to weaken, crack, or develop pinhole leaks. A degraded diaphragm directly impacts pump efficiency—leading to pressure fluctuations, reduced output, or complete failure to prime. Installing a fresh diaphragm assembly restores the pump’s volumetric efficiency and prevents internal leakage that could damage adjacent components.
| Pumping action | Converts rotational motion into fluid movement via reciprocation |
|---|---|
| Pressure generation | Forms a moving seal to build and sustain operating pressure |
| Fluid isolation | Separates the fluid path from the pump crankcase or motor |
| Low/erratic pressure | Gauge fluctuates or won't reach set point |
|---|---|
| Priming difficulties | Pump runs but doesn't draw liquid |
| External seepage | Fluid visible around pump housing or weep holes |
| Contaminated oil | Milky appearance indicates fluid intrusion |
This diaphragm assembly (part 2369431) is specifically designed for the Elite 3000 model. For absolute certainty, cross-reference your sprayer's serial number with the parts manual before ordering.

When you replace the diaphragm, it's a good opportunity to refresh other wear-prone pump components. Below are items commonly ordered alongside the 2369431.
Includes inlet and outlet valves; worn valves cause pressure loss even with a new diaphragm.
All O-rings and gaskets that seal the pump head; replace to eliminate future leaks.
If the head is cracked or heavily corroded, complete replacement may be more cost-effective.
