Part 2393138 is a replacement service set diaphragm for Elite 3000 equipment. This diaphragm is a flexible sealing component used in pressure regulators, pumps, or valves, responding to pressure changes to control flow. When the original diaphragm becomes worn, torn, or loses elasticity, replacement restores proper system function.

The 2393138 service set diaphragm is a direct replacement component for Elite 3000 equipment. This flexible membrane is a critical element in various devices such as pressure regulators, unloader valves, pumps, and actuators. It responds to pressure differentials by flexing, which in turn moves a valve or other mechanism to control flow, pressure, or system operation. The diaphragm must be flexible, durable, and resistant to the fluids it contacts to ensure reliable performance and a long service life. A properly functioning diaphragm provides accurate control and positive sealing. A worn, torn, hardened, or punctured diaphragm can cause loss of pressure control, erratic operation, internal leakage, and system failure. Symptoms may include pressure fluctuations, failure to maintain set pressure, or fluid leaking through the vent. This replacement diaphragm is manufactured to exact specifications for size, thickness, material, and shape. It is made from a compatible elastomeric or composite material resistant to paints, solvents, and hydraulic fluids. Installation requires disassembly of the component, careful placement of the new diaphragm, and proper reassembly.
| Pressure response | Flexes in response to pressure changes |
|---|---|
| Actuation | Transmits motion to control valves or mechanisms |
| Sealing | Provides a barrier between fluid chambers |
| Torn / punctured | Diaphragm damaged, causing leaks or loss of control |
|---|---|
| Hardened / brittle | Material lost flexibility, affects response |
| Worn / stretched | Diaphragm deformed, no longer functions correctly |
| Pressure instability | System pressure fluctuates or drifts |
