Product Description
Armstrong SG-2515 Suction Guide – 2-1/2" x 1-1/2" ANSI 125 Flanged (516860-034)
The Armstrong SG-2515 suction guide (part number 516860-034) 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. With a 2-1/2" inlet and 1-1/2" outlet, it replaces an elbow, strainer and straight run of pipe in one compact fitting, saving space in mechanical rooms. It is rated for 175 psi and 300°F, and the SG-2515 has a ductile iron body and guide vanes with a stainless steel strainer.
