In my barn I have a terrible water supply that only offers about 150 gallons/hour max flow. That's not enough for equipment washing, tank filling, or even using a pressure washer. It also won't do squat in the event of a fire.
My solution to this problem has been ten 55 gallon drums all plumbed together, which fill up slowly as a reservoir and then I use a pump to power my "hose". I use the hose mostly to water things and clean equipment.
I have gone through more than a few cheap crappy electric pumps and I'm tired of dealing with them. They never live up to the advertised specs, it's either flow or pressure, not both. I've even tried using multiple pumps in series. Ideally I would like to push at least 1000GPH out of a heavy duty 3/4" garden hose at 50-100 PSI.
So, I have decided I need to make a gas powered water pump for my tasks. I was thinking about using this roller pump from surplus center along with a 5hp engine:

Obviously I would have to belt drive it to slow the pump to 1200 RPM max. Does this seem like an appropriate pump for what I want to do? I don't know much about "roller" pumps, but this one seems to offer a ton of output and pressure for a reasonable price. What difference does the number of rollers make? I already have the engine. Will this thing truely put out 17.3 GPM at 100 PSI like it claims to? Is a pump like this "self priming"?
