ABSTRACT:
Centrifugal pumps and similar fluid handling machines may be tested to detect leakage from shaft seal assemblies by an apparatus which includes a support flange for supporting a section of the pump casing including the seal assembly. The apparatus includes a housing portion with an interior chamber which may be placed in communication with a source of pressure fluid such as compressed air to act on the seal assembly to detect any fluid leakage therefrom. The apparatus includes a cylindrical support flange and removable adaptor plates which may be interchanged depending on the configuration of the pump casing.
