HIGH SPEED PUMP: MECHANICAL SEAL BAD ACTOR RESOLUTION
Abstract
Case study include a vertical pump in sour water service running at high speed of 17200rpm. Pump originally equipped with single seal & Plan 21 configuration since day one. In 2018, as part of a reliability upgrade, seal was converted to a double seal design (Plan53A). Pump MTBF reduced from 24 months to 6 months. While utilizing existing Plan 53A, a practical & cost effective approach is to have external cooling supply to seal chamber. Plan 32 then is introduced; together with seal scallop design upgrade and reducing amount of elbows on current seal piping system. With new upgrade changes, the pump seal has been operating satisfactory since commissioning, exceeding its previous operating life.
