Abstract: A coffee brewing device of the percolator type. Fundamentally, the invention comprises a pot for receiving liquid therein and having positioned at the bottom thereof a cylindrical pump member characterized by an essentially flat top and by a tubular pump chamber of greater radial length than the vertical depth of the pump chamber at the top of the pump member. Six to ten uniform holes or orifices of a total area of between about 0.0258 and 0.043 square inches are provided in uniformly spaced relationship about the bottom of the pump assembly. Received within the pump is a dual element fat-topped heater consisting of a core having two heating element wires wrapped thereabout in a parallel spiraling fashion. The flat top of the pump member is spaced from between 1/16" and 1/8" from the flat top of the heater.
