Abstract: An overhung external spur gear positive displacement pump for hot oil or deep fryer applications is disclosed. The external gear pump includes a casing that includes a through bore for accommodating a drive shaft that leads to a pump chamber that accommodates a drive gear and a driven gear. The casing further includes a recess connected to the pump chamber for accommodating a stationary pin. The casing also includes a proximal end coupled to a prime mover and a distal end coupled to a head. The gears are enclosed in the pump chamber by the head. The stationary pin is accommodated within the driven gear and the drive shaft is coupled to the drive gear. The head is provided in the form of a flat plate with a plurality of holes for accommodating fasteners that couple the head to the distal end of the casing.
