Any alternatives to this Berkeley pump type?

[RickFlorida]

I have an old irrigation pump that I want to replace and it looks like this. (mine is an old Sta Rite maybe? and this one says Berkeley). Are there any recommendations for a cast iron 1.5hp pump besides the Berkeley that look like this? I'm curious what other brands make this type because this type does work well with my sprinkler system. It's just has too much corrosion from many years of life, I doubt the sealing plate is good.
