Cantilever

Discflo vertical cantilever disc pumps for tanks and sumps. All wear parts sit above the fluid line, so there are no submerged seals, bushings or bearings; the motor is mounted above the liquid level and the pump can run dry. Rotating discs replace impellers and vanes. Handles abrasive slurries with up to 80% solids and particles up to 10 in. (250 mm), with high suction lift and no radial load. Built in rugged alloys such as CD4MCu and Hastelloy.
