The Jandy R0479701 Pump Diffuser is a genuine OEM replacement component engineered to restore optimal hydraulic performance in Pro Series 1.5–2.5 HP pool pumps. This complete assembly includes the diffuser body, O-ring gasket, and all necessary mounting hardware—ensuring a proper, leak-free fit and reliable performance.
The diffuser plays a vital role in channeling water flow into the impeller and maintaining consistent pressure throughout the pump housing. When worn, cracked, or misaligned, a damaged diffuser can reduce pump efficiency, increase noise, and shorten impeller life. Installing the R0479701 restores smoother water flow, improved pump operation, and longer component life.
