Cast Iron Back Pull Out Suction Diffuser

Their flow straightening vanes ensure laminar flow without the need for 10 pipe diameters of straight pipe run into pump suction. They also eliminate other fitting such as 90 degree elbows and Y-strainers. The stainless steel strainers are designed to have at least 3 times the free area of the outlet nozzle. The removable fine mesh startup strainer removes initial system debris to protect the pump seals during startup. The Back Pull Out design simplifies strainer cleaning and startup strainer removal.
