Abstract
An assembly is disclosed for forming a fluid-tight seal between a pump housing and a seal plate. The housing includes a first flange with a first plurality of apertures formed therein, and the seal plate includes a second flange with a second plurality of apertures formed therein. A gasket is provided between the pump housing and the seal plate. A plurality of inserts extend through the first plurality of apertures, and a plurality of spacers extend through the second plurality of apertures. A plurality of threaded connectors are used to couple the seal plate to the pump housing to form a fluid-tight seal. The dimensions of the inserts and spacers are selected so as to inhibit crushing of the gasket and the flanges when the connectors are fully tightened.
