VS-CNC Vertical Non-Clog Sump

The VS-CNC 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 large spherical solids, chemical attack, metallic solids or high temperatures.  VS-CNC pumps use the non-clog CNC fluid end for hydraulic performance using a specially designed two-vane, large solids handling impeller.  This heavy wall, enclosed, two-vane, 304 investment cast stainless steel impeller design provides a durable and dependable product and is perfectly suited for large spherical solids with stringy material present.  This fluid end is designed to be used in the most aggressive of applications with solids passing capability through 7 inches (180 mm).  The flexibility of material combinations makes this product adaptable for the steel mill, mining, power generation, municipal and oil & gas applications.
