This paper describes a new measurement method using fluorescence analysis to measure oil pump rates of radial lip seals for small shaft diameters. A test apparatus and operating procedure for measurement of pump rate were shown. First results of pump rates obtained with seals for 8 mm shaft diameter were shown. As a result, the oil pump rates under various shaft speeds and sump pressures ranged from 4 to 160 mg/h.
