Cornell's SP Series Slurry pump is equipped with patented Cycloseal® technology that caters to the Crushed Stone Industry. It offers a diverse range of mine dewatering pumps and serves as an ideal solution for abrasive applications throughout the mill process. The SP Series Slurry pump is available in both rubber and metal-lined configurations to handle different particle sizes and pH requirements. Thanks to Cycloseal® technology, the pump can run dry for an indefinite period. Can your slurry pump do that? The strictest standards are maintained in the manufacturing of Cornell's slurry pumps for coarse abrasives, making them ideal for the Crushed Stone Industry.

This slurry pump is unique in the sense that it can operate continuously without any damage and has a lifespan that is three to four times longer than its competitors. Unlike other pumps, it doesn't require a water supply line to the stuffing box, which means you don't have to worry about leaks or wear costs. This pump is built to last and can run for a long time, giving outstanding performance.

• The pump uses a metal impeller as standard.

• The design can also accommodate a molded rubber impeller in the future.

• The casing is made of strong spheroidal graphite iron, while the suction inlet and casing are lined with natural rubber.

• The impeller and other wet-end components are made of highly abrasion-resistant high-chrome white iron, with a Brinell hardness of 680 to 720.

• The high-chrome impeller can withstand "tramp" metals and achieve higher tip speeds.

• The radial impeller vanes can clear solids and reduce pressure at the suction-side clearance, which reduces solids grinding and recirculation.

• The tight back liner clearance maximizes packing and shaft sleeve life. Usually, this clearance is opened up as the impeller wears and needs adjusting.

• The reverse taper roller bearings purge grease to the outside to prevent the ingress of slurry and over-greasing of the bearing cartridge.

• The tight clearance between the wear ring and impeller reduces suction-side slurry recirculation by up to 95%.

• Pumps feature a patented, adjustable suction-side sealing system that includes a wear ring that runs against the machined face of the impeller near the eye.
