Spraytech part 270201 is a Diaphragm Assembly used in the pump of compatible Spraytech airless sprayers. This diaphragm is a critical component that flexes to create pressure and move fluid through the system. Replacing a worn, torn, or hardened diaphragm restores pump efficiency, pressure consistency, and prevents internal leakage.

The Spraytech 270201 Diaphragm Assembly is a genuine OEM replacement part designed for the ED1150 Plus airless sprayer. The diaphragm is the heart of the pump, flexing back and forth to create the pressure needed to atomize paint and deliver it through the spray gun. It works in conjunction with the pump's fluid section to ensure consistent flow and pressure.
Over time, diaphragms can become worn, develop small tears, or lose their flexibility due to constant flexing and chemical exposure. A failing diaphragm may cause pressure fluctuations, reduced output, or complete loss of prime. Replacing the diaphragm assembly restores the pump's performance and helps prevent further damage to the fluid section.
| Pressure generation | Flexes to create the pumping action that pressurizes fluid |
|---|---|
| Fluid flow control | Helps maintain consistent output for smooth spraying |
| Separation | Separates the fluid side from the drive mechanism |
| Loss of pressure | Sprayer struggles to reach or maintain operating pressure |
|---|---|
| Fluid leaking into drive | Paint or fluid visible in the pump housing or drive area |
| Visible damage | Tears, holes, or hardening of the diaphragm material |
| Erratic spray pattern | Pulsation or surging during operation |
Spraytech part 270201 is compatible with the following Spraytech sprayer model. Always confirm fitment using the correct parts diagram for your exact model and revision.

When replacing the diaphragm assembly, these associated components are often inspected or replaced at the same time.
Worn valves can cause pressure loss and poor priming; consider rebuilding the valve assembly.
Replace any seals or gaskets in the fluid section to ensure a leak-free assembly.
A clogged filter can put extra strain on the pump; clean or replace as needed.
