Vertical Cantilever Pumps Manufacturers

Vertical cantilever pumps are designed for installation in a sump or tank where it is desirable, having only the casing and impeller submerged in the pumpage for priming. The support bearings for the rotating element are located remotely above the pumpage in a dry environment. There are no throttle bushings, bumper bushings, or rings of any type located at the impeller or submerged below the maximum normal water level. They are tolerable for a wide range of liquids, limited only by liquid end configuration and materials. Cantilever pumps are centrifugal pumps commonly used in sump pump applications. They are available in horizontal and vertical configurations, and many styles including submersible motors. They are frequently used in slurry and solids handling applications. They have no submerged seals, bearings, bushings, or suction check valves. The cantilever or overhung shaft is supported by heavy-duty ball bearings that are located above the pumped liquid. There are also a variety of material options for corrosion and abrasion resistance. Cantilever pumps are available with a number of different impeller types, which change the nature of the flow through the pump.
