That price doesn't sound bad to me, I don't know anywhere to find prices for the bigger stuff online. 20 hp seems small for 900 gpm to me.
I have a 15HP that'll do 800gpm. I was hoping for 1000 with the 20HP. Not a whole lot of lift. According to Google earth elevation change is only 12' or so from where the pump is to where it pumps to. Static water level is about 12' below ground level, and the pump itself is probably 40' deep max. So From where the pump is to where it pumps to is going to be probably a max of 50' of lift. The place I have been getting them from will sometimes trim the impeller of a larger pump to fit onto a smaller motor to get it under the max amperage draw for that HP motor and maximize flow.
So yeah, I should probably just bite the bullet and get a pump coming. Probably ought to wait until I after I sell some calves though because I just bought another big baler today and need to let the bank acct recoup some. Old pump is still pushing around 600gpm right now. Will probably send it back to them to have them rebuild the pump end and check the motor when I swap the new one in and that way I'll have a good spare.
