I currently am running a Submersible pump from a stream for my lawn, I want to switch to a above ground pump. I am looking at a Zoeller 2HP Irrigation / Sprinkler System Pump, can someone help me see if it will do the job for me I don't understand all the calculations. Here is what I have 12ft rise from water to where pump will be I have 600ft of piping to my furtherest sprinkler head with an elevation rise of 50ft. I have 1 1/2 pipe running from stream 450ft then it reduces down to an inch pipe I have 6 sprinkler heads per zone running about 3gpm each and require at least 25 psi. Can someone tell if this pump will do the job. If you would need more info just let me know and thanks with any help. Here is the model pump
