3171 Vertical Sump and Process Pump
The Goulds Model 3171 is the industry's veteran vertical sump and process pump, with thousands of installations worldwide in industrial process, sump drainage, corrosive liquid handling, pollution control, and molten salt applications. API 610 11th edition VS4 compliant, the 3171 family covers the full range of vertical sump service from standard industrial drainage through severe corrosive and high-temperature process duties. The product line includes five variants: the standard 3171 (open impeller), CV 3171 (recessed impeller for solids and shear-sensitive fluids), LF 3171 (low-flow, high-head), NM 3171 (non-metallic for severe corrosives), and API 3171 (API 610 VS4 compliant for refinery and petrochemical service).

Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
