I have one of these well made irrigation pumps from Sta Rite. But mine is over 25 years old I estimate. I'm moving the location of it and decided I should rebuild it. The Artesian well water has created a thick and hard shell of black scale on inside of the pump. I think I should remove it or the shattered pieces could jam up the pump during operation. Is there an efficient method to remove it? I'm using rust dissolver but that really only works once the exposed cast iron is free. I can take a chisel and hammer chunks of it off but it's very slow and inefficient. Is there a chemical bath that works well for this? A new pump of this quality is 900 bucks (they actually still sell these according to the internet) so I don't mind putting a lot of time and effort in this. I'm going to enamel paint it when done.
