The Gast 0523 pump was tested last night without the filter attached and I found that the amp draw was slightly lower than with the filter in place. It was about 0.1 to 0.2 amps higher with the filter inline. I am going to call it "good enough". The filter I used was from McMaster Carr...part number 4369K31. It has a spec of 10 scfm @ 100 psi which did not really tell me much, hence the need to verify that it was not choking the pump at much lower CFM's.

I will take some other readings as the system is put into place, but for the near future I am in a hustle to get the pump house erected and the system functioning before the heat and lack of rain takes a toll on the pond.

Fish on!,
