Armstrong 516860-020 SG-43 Suction Guide 4 inchesx3 inches Flanged

Product Description

The ARMSTRONG 516860-020 SG-43 Suction Guide is a multi-functional pump fitting designed for direct mounting on the suction flange of horizontal and vertical pumps. This 4"x3" flanged unit protects against debris, optimizes flow, and saves space by integrating a 90-degree elbow, guide vanes, and an in-line strainer. Constructed from cast iron, ductile iron, or carbon steel, it is rated for a maximum pressure of 175 PSI and temperatures up to 300°F, ensuring durability and efficient operation in hydronic pumping systems.

• Versatile 4-function design saves space and installation costs by incorporating multiple devices into a single solution.
• Guide vanes reduce turbulence, creating optimum flow conditions and minimizing stress on pump components.
• Strainer is star-shaped for added strength and designed to provide large free flow area to reduce pressure drop.
