Product Description
Armstrong SGG-104 Grooved Suction Guide – 10" Grooved x 4" ANSI 125 Flanged (546880-064)
The Armstrong SGG-104 grooved suction guide (part number 546880-064) is installed at the suction side of a centrifugal pump to turn the flow 90°, straighten it with internal guide vanes and strain out debris before it reaches the pump. It has a 10" grooved inlet from the system – compatible with standard cut groove pipe fittings such as Anvil or Victaulic – and a 4" ANSI 125 flanged outlet to the pump. It replaces an elbow, strainer and straight run of pipe in one compact fitting. Rated for 175 psi and 300°F, the body and guide vanes are ductile iron (ASTM A536 grade 65-45-12) with a stainless steel strainer.
