VS-CSG Vertical Process Sump

The VS-CSG vertical sump pumps are used in a variety of applications where submersible pumps are not a good fit. Many applications require a vertical sump pump in lieu of a submersible due to site conditions, such as chemical attack, metallic solids or high temperatures. VS-CSG pumps use the ANSI Process CSG fluid end for hydraulic performance using a process designed semi-open impeller. This heavy wall, semi-open, 304 investment cast stainless steel impeller design provides a durable and dependable product and is perfectly suited for petrochemical applications. This fluid end is designed to be used in the most aggressive of applications. The flexibility of material combinations makes this product adaptable for the steel mill, mining, power generation and oil & gas applications.
