Abstract
A self-priming transfer pump incudes fluid inlets and outlets that employ camlock fittings. The self-priming transfer pump also includes a unique motor plate and pump housing to allow a quarter-turn attachment after lining a splined motor shaft to a unique splined female mating portion. There exists a pump cartridge permanently affixed to the pump housing to eliminate user exposure and need for tools when replacing or changing out the pump. A quick connection and disconnection of pumping section from motor section requires no tools. An external locking mechanism prevents the pump section from rotating and disengaging from motor section. Multiple pump sections are usable with a single motor to prevent cross-contamination between products being pumped.
