Needed more capacity then I was getting with current pump and also one that holds up well. I have used it for a few acres only but very pleased with the pressure and GPM for 540 RPM.

Need more gpm for 540 RPM than my other pump was giving me and bought this one for the gpm and then the stainless for the life over the cast pumps. I have used it only one day but very pleased. Getting higher gpm running much lower rpms than their 6 roller giving me the pressure needed. I looked and studied both Delavan and Hypro and the Hypro stainless was a good bit more than Delavan is. Oh ordered the pump over the phone and very reasonable shipping fees and quick.
