I am new here and I am not really sure where to post this question. I am also not an Engineer, so general language would be appreciated.
I sell Water Well Pumps at my location and on the Internet among other things. Today I had a call from a Man who wanted a Pump that was going to Africa. He needed 170 gallons per minute at 360 feet of head. No problem, a 30 hp motor and the right liquid end will do the job. Problem is, my book had pump curves for motors that are 60 cycle. In Africa I believe they have 50 cycles like most places around the globe. This means my motor which will spin at 3450 rpm's at 60 htz; and will spin somewhere around 2700 rpm's at 50 htz. Now the pump can't do what my curve said it would.
My question: How would you figure out which pump and motor to sell this man with only the 60 cycle pump curve?
Thanks in advance
