There is shown a pressure loaded external gear pump with a low pressure lubrication system. The low pressure lubrication system utilizes the viscous shear pumping effect which occurs between the shafts and bearings to draw fluid from the inlet port, circulate it past the bearings and then return it to the inlet port.
