Abstract
Discloses apparatus for use with a modular fluid pump assembly, particularly pumps used to pump fluids containing entrained contaminants such as grit. The apparatus includes a pair of removable end plates attachable to a modular pump housing. A bearing assembly is detachably mountable on the exterior of the and plate and provides a cavity to receive a pump shaft fitted with a shaft seal and shaft bearing. A grit collar to surround the pump shaft is mountable on the interior side of the end plate. Replacement of the pump seals or bearings can be effected by removing the bearing assembly. More extensive maintenance, such, as replacement of the grit collar or pump gear or shaft, can be effected by removing the end plates.
