Abstract: A pump for pumping a fluid includes a motor, a drive shaft, an impeller, a pump housing having an inlet and an outlet portion, and an extension tube extending between the motor and the pump housing. Preferably, a portion of the fluid to be pumped is contained within the extension tube at a relatively constant level to provide a seal.

Abstract: A fryer/cooker assembly for cooking fast foods and the like at a predetermined constant temperature and without contamination between various types of food products includes a kitchen cabinet assembly having a cooking pan at an upper portion thereof which is removable for cleaning. The cooking pan is provided with a dispersing pipe substantially around the complete inner circumference thereof. This pipe has a plurality of oil dispersing holes, each hole being at approximately 30.degree. to the cooking pan bottom. A baffle plate over the dispersing pipe provides a gap between the lower edge thereof and the cooking pan bottom of approximately 1/4 inch.A heater/heat exchange unit of high efficiency, high temperature output receives, through appropriate piping, cooking oil to be heated to a desired set temperature. Temperature probes in the pan and the oil input to the heater/heat exchanger coupled with thermostat control structure accurately maintain the temperature of the cooking oil at preferably 325.degree.
