Abstract To avoid the seals failure due to the increasing temperature caused by the friction motion in medium or high pressure reciprocating pump, it is necessary to consider the frictional temperature in the design of seals to ensure that the highest temperature on the friction interface is not greater than the allowable temperature of seal material. The maximum temperature on the interface by the friction motion is mainly influenced by the surrounding temperature, the frictional temperature of contact body, and the frictional temperature rise on the interface between contact bodies. The formula of frictional seals′ temperature for reciprocating pump is derived. And a concise formula of the increasing temperature on the frictional interface is proposed for designing and checking the seals for the reciprocating pump, which is based on the classical analytic computational formula of friction surface temperature. The feasibility of the proposed concise formula is validated by the comparison of calculation and experimental results. Results in present work would provide the reference for choosing and designing of seals in reciprocating motion from the view of the frictional temperature.
