Armstrong International 51690 SG-88 Suction Guide

Armstrong SG-88 Suction Guide (part number 516860-528) is a compact, in-line suction fitting for centrifugal pumps that integrates a 90-degree elbow, guide vanes, and an inline strainer to streamline the suction path and protect the pump from debris. In the SG-88 configuration, the inlet and outlet ports measure 8 inches (203 mm) apart, forming an 8x8 footprint, with a PN16 (16 bar) rating and a weight of about 213 lb (96.6 kg). Replacement parts for this model include a Strainer assembly (516900-000) and an EPDM O-ring (9.475.d), supporting straightforward field maintenance. Designed to mount on suction lines within Armstrong pumping systems, the SG-88 aims to improve flow characteristics, reduce surge, and contribute to reliable pump operation in compatible installations.
