Case Study 3: Book of Gold

Book of Gold Case Study False Brinelling Pump Motor

False Brinelling on a Standby Pump Motor

This is the third video case study from the ‘Book of Gold, Practical Condition Monitoring Case Studies’ (#BookofGold) by James Sylvester. In this video James is back in his garden shed sharing a case study that he hopes helps answer the question, how to prevent false brinelling on a standby pump motor. This is a set of pumps on seperate metal base frames secured to the same concrete bed with a common inlet and outlet pipework.

      Hi Carlos. Thank you for your interest in the Book of Gold. We do offer international shipping to Columbia (Rest of World), but you may prefer to visit the Noria site in the USA, as it will save more on the shipping. If you do prefer to order with RMS, we will be able to despatch towards the end of next week, with a delivery time estimated around 10-15 working days.
