Elastomeric radial lip seals are complex tribological systems. Their sealing performance is essentially determined by the back pumping capability of the system. During the dynamic operation, radial lip seals can actively pump leaking fluid back to the fluid side. For the assessment of the pumping capability and the leak-tightness of the sealing system, the pumping rate can be used. The pumping rate measures the pumped fluid volume per time or distance. In this paper, the influence of low operating temperatures on the pumping rate of elastomeric radial lip seals is analysed experimentally. For this purpose, the pumping rate was measured at different oil sump temperatures between +40 °C and 20 °C. The experimental analyses were performed with radial lip seals made of nitrile rubber (NBR) and fluoro rubber (FKM) in combination with mineral and synthetic (polyglycol and polyalphaolefin) oils.
