I have been using the Evo pumps on Briggs engines for about two years now…no issues whatsoever. These are the direct drive pumps. I remove the pumps from the engines every six months to check for wear on the shafts…nothing yet.
My thinking was that if I got 12 months use from them I could take them off and throw them away and fit new.
The 14hp 2100's are better on fuel (or seem to be) than the 11hp Gx390's due to them not working flat out.The nail sea frames don't seem to shake themselves apart. The K1's are totally reliable.
I was/will get Ben to build me some more when the time comes ….but I am still waiting for the machines to fail!
These machines are ideal for constant use in the domestic /industrial market. The combination of the flow/pressure make the nozzle size spot on for max performance from a FLC. We rarely have to stand around due to lack of water from domestic supplies .What water we do use is used to maximum efficiency (full power at full flow) through the nozzle.
I would imagine Ben you build these machines at very good prices ( and still take a profit) compared to what else is on the market.
Thats what I like about this forum …people ask advice ,people take time to give in depth relevant answers to the questions asked. People then go and do the opposite
