I bought two (2) of these pumps. It was a mistake as I ordered over a Holiday weekend. I did not receive any kind of confirmation and then ordered again thinking that there was a glitch in my computer. Well, I received both and did pay whatever the price was. Then thinking that I would need a spare in case one went down. Has never happened and one is still in the box with booklet and all.
Hypros are great pumps. I have several types as I do a lot of stuff such as spray orchards, fields, and lawns. We have a roller pumped mounted on a moveable surface that is used to fill barrels with water from a creek when spraying fields, fences, orchards, etc. I'm only spraying my lawn, a neighbors and mother-in-laws so the one that Im using will last me forever.
Anyway great pump. My skid sprayer has the Honda 5HP from Northern Tools.
If you've never used a Diaphragm Hypro Pump, they use non-detergent oil which has a sight glass (Weirglass) that you observe when operating.

Let me know if you want this one as I'm putting it on Ebay in the spring.
I've owned a hypro before. My first skid sprayer was a Lesco space saver 200 gallon. 5.5hp Kaw with D403 pump. I actually replaced the pump on it myself shortly after I bought it used. Ordered the pump in Tulsa, OK. drove 2 hours to pick it up for $700, then replaced it in the garage at home that night. Just don't ask me WHY I had to replace it (rookie move) Note to self: put rv antifreeze in the pump in Winter and don't try to operate it when the diaphrams are bad lol
On a serious note, I didn't use the locktite on my old D403. It had the nice $380 gear reduction box and the whole 9 yards. I was a fool for getting rid of it. But... live and learn. How would we do this transaction if I bought it from you? Obviously, you don't know me and I don't know you and $400 is alot of money.
