The original turbopumps were marginal. They had alot of problems with turbine blade breakage and whirl. In the 80s Pratt & Whitney was contracted to re-design the pumps. They were heavier but much more reliable. There's a good chapter about it in this book. https://www.amazon.com/Advanced-Engine-Development-Pratt-Whitney/dp/0768006643/ref=sr_1_1?ie=UTF8&qid=1549462334&sr=8-1&keywords=mulready+pratt+%26+whitney
