Bell & Gossett

The Bell & Gossett Suction Diffuser is an angle pattern flow straightening fitting that combines a diffuser-strainer orifice cylinder and full length straightening vanes to provide ideal flow conditions for the pump suction. It saves space and money by eliminating the need for long or short radius elbows, reducing flanges, and long lengths of pipe leading into the suction side of the pump. Its full length straightening vanes help provide a fully uniform flow pattern into the pump, reducing uneven stress on the pump impeller and shaft and extending the life of the pump.

B&G Suction Diffusers are available in a wide range of sizes, from 2"x1½" to 10"x10". Users can select from a choice of steel or stainless steel orifice cylinder and straightening vanes, and models are available with flange, groove, and NPT (up to 3"x3") end connections. All Suction Diffusers are suitable for up to 250F max temperature. Flanged and NPT models are rated for 175 psig max working pressure, while grooved models are suitable for 300 psig max working pressure.
