Abstract
A flexible impeller pump having a transparent safety cover. The pump includes a flexible impeller and a housing having a pump and cover. The pump end cover comprises a transparent safety cover which is capable of attachment to the housing. A transparent heat resistant insert is also in contact with the impeller. A spacing means separates the transparent heat resistant insert from the safety cover, thereby forming a chamber. Typically the transparent heat resistant insert is made of borosilicate glass and the transparent safety cover of acrylic plastic or polycarbonate plastic.
