Pacific Boiler Feed
Application: Boiler Feed
Pump Details: Pacific 6LL BFIDS 10-Stage
Pump Type: Barrel
A major Power Plant had been experiencing vibration problems with their Pacific boiler feed pumps, and though repairs had been made at the plant, the mean-time-between-repair was between 6-9 months. The plant pulled the pump and sent it to Hydro for an independent evaluation.After a thorough analysis of the system, the pump’s history, and an inspection of the pump in our shop, Hydro determined that though an A-B Gap modification was the proper solution, the previous modification had not been correctly designed.
Hydro performed the modification on the first of three pumps in 1989 and this pump ran for 11 years with no problems. When it was pulled in 2000 for routine maintenance, only a standard ring and bushing job was needed. Over time, all three pumps were modified and are still running today.
