Material Innovations For Cutting And Chopping

"The Barnes Sithe chopper pumps have a patented open center cutting technology. Cutter blades are made of 440C Heat Treated Stainless Steel and have a hardness of up to 60HRC. Sithe chopper blades can chop and pass hard solids in the waste stream including wood, wire, plastic and small metallic parts. There are hundreds of Sithe chopper installations in extremely demanding waste water applications including correctional facilities, hospitals, zoos, dairy farms and schools where blade sharpness is still pristine even after thousands of hours of operation. Sithe chopper pumps perform a slicing action on solids compared to harsh chopping action. The smooth slicing action exerts less stress on the chopping blades and result in longer cutter life."
