I have a NEW Hypro 252 with reduction gear and regulator for $400 which bolts directly to your engine. Probably about the same cost as a Pump and Reduction Gear alone.
The 4101 roller pump is rated at 2600 RPM. It's built to couple direct to a 2.5hp engine. That's why I went with a 79cc engine instead of spending $17 more for Harbor Freight's 5.5 hp engine. I looked at D252s and just about every pump there is before I started ordering parts for my skid. I private messaged several people on here for their opinions also before making a decision. I had actually settled on a package from Rittenhouse that had a Honda GC160 with D252 for about $900 but at the last minute decided against it. My setup= $215 If you divide $900 by $215 it comes out to a little over 4. This means that I can literally wear out my engine and roller pump 4 times, throw it in the trash, and purchase new before equalling the cost of the package I was going to get from Rittenhouse. If we start talking about D30 and D403s, I could replace my engine and pump more than 4 times.
That being said.... I do plan to buy a nice diaphram pump in the future. I just want to make sure I have the clientele to justify it. I've made alot of bad business decisions in the past which is why I micro manage my money these days. I think your offer on the D252 is a good price. Why are you selling it if you don't mind me asking?
