Abstract

A safety cover for the fill port of a self-primer pump is structured to improve the seal between the fill port cover and the fill port in the pump casing to thereby control the release of steam from the pump, and includes an improved sealing band between the fill port and fill port cover, an improved fill port cover design and an improved retaining clamp design.
