Xylem-Bell & Gossett Suction Diffuser Plus

The Xylem-Bell & Gossett Suction Diffuser Plus is an angle-pattern suction diffuser (also called a pump suction diffuser or straightening fitting) for HVAC, hydronic and water-circulation piping. It mounts on the suction side of a pump. It conditions the flow entering the pump so the system can keep its pump efficiency.

Key Features:

• Flow Cone design: Directs flow out of the diffuser and into the pump suction. This reduces the recirculation zones found in many suction diffuser designs. The result is a more uniform velocity profile at the pump inlet.
• Cast iron body: Durable construction for commercial and industrial piping systems.
• Built-in strainer: A 16 mesh bronze strainer helps keep debris out of the pump.
• EPDM o-ring: Seals the strainer and cover.
• Ratings: The ED-3X and FF-3X are rated to a maximum working pressure of 175 psi and a maximum operating temperature of 250°F.
• Space-saving, two-in-one fitting: It combines the functions of an elbow and a strainer. This can reduce the amount of pipe and fittings needed near the pump.
• Flanged connections: Available in multiple system-side and pump-side configurations.

A more even flow into the pump reduces uneven stress on the impeller and shaft. This helps retain pump efficiency and lowers energy costs. The Suction Diffuser Plus line suits HVAC systems, water treatment and other facilities that need reliable pump operation.
