Dayton seal plates prevent dust infiltration from damaging the internal components of a pump including the shaft sleeve, impeller & the bearings to allow smooth rotation. These units are provided with gaskets for creating an oil-tight seal between the flange faces and keeping contaminants from accumulating at the joints. They also have a set of screws to join the sections securely. They feature steel construction with powder painted finish to resist corrosion and are available for use with Dayton centrifugal and utility pumps.
