Shaft Sealing Systems for Centrifugal and Rotary Pumps--API 682--is the new standard of the American Petroleum Institute for heavy duty pumps in refinery services. It is not a standard for mechanical seals per se. Rather, it is a standard for mechanical seals used in pumps manufactured to API standards 610 and 676 for pumps. Therefore, it recommends only three basic seal types for pumps used in an estimated 90% of all refinery services. While standards to a large degree are rigid, API 682 also allows sufficient latitude in many aspects to keep critical application-specific decisions in the province of the individual pump specifier. The range of variables is great. Therefore, it will be important for pump specifiers to be very exact in ordering sealing for a given pump. The paper reviews this standard by discussing operational ranges; benefits; standard applications; testing requirements; auxiliary equipment; and cost factors.
