CNC Non-Clog

The CNC non-clog pumps are used in a variety of applications where the fluid has large solids present.  Many applications require a heavy duty pump designed to pump large spherical solids.  The CNC fluid end uses 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.  The enclosed impeller features pump out vanes on the front and rear shrouds to minimize solids buildup.  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.
