Product Description
Armstrong SGHH-88 Suction Guide – 8" x 8" ANSI 250 Flanged (516860-228)
The Armstrong SGHH-88 suction guide (part number 516860-228) is the high-pressure ANSI 250 flanged version of the Armstrong suction guide. Installed at the suction side of a centrifugal pump, it turns the flow 90°, straightens it with internal guide vanes and strains out debris before it reaches the pump. With a 8" inlet and 8" outlet, it replaces an elbow, strainer and straight run of pipe in one compact fitting. It is rated for 375 psi and 300°F, with a ductile iron body and guide vanes and a stainless steel strainer.
