Corrosion Problems in Electrical Pumps: Identification and Solution

The main objective of this study, was to examine the corrosion resistance, of various components of an electric pump. Three types of aqueous solutions, such as tap water, Sodium Hydroxide (NaOH), and Hydrochloric acid (HCL) solutions, were used to examine corrosion rate of components of the pump. Three samples from each pump component were prepared as coupons and samples were soaked in solutions for about 17 days (404 hours). At the end of the soaking, weight loss measurements were taken, from the soaked samples, and accordingly, the corrosion rate for each coupon were calculated. As such, a possible solution for such cases were identified.
