Abstract
A removable cartridge-type pump for live well bait tanks in sport fishing boats wherein a motor impeller unit can be rapidly inserted and removed from a housing to which an input pipe is connected so as to clean the impeller and pump cavity and/or replace it with the different unit. An O-ring seal between the housing and the impeller unit serves as a liquid seal and also as a spring bias between the units. Either a bayonet connection or a screw connection may be made between the units and locking sears are provided so as to positively lock the units together.
