Abstract
A corrosion detector for use with a sealless centrifugal pump. The corrosion detector having a corrosion coupon at one end of the detector. The corrosion coupon being formed of the same material as the pump containment shell and having a thickness approximately two thirds the thickness of the containment shell. The corrosion detector is preferably installed in a bore in the pump discharge flange such that the corrosion coupon is exposed to the velocity of the pumped fluid. A detector is mounted within the corrosion detector to detect any leakage of the pumped fluid through the corrosion coupon. The corrosion coupon is designed so that this leakage will occur before the containment shell has failed or begun leaking due to corrosion.
