I have had one pump failure on my Alky Controls setup. That was nearly 3yrs into having owned it, & using it rather heavily.
Used it so much that many who know me, often commented on my developing meth addiction. Lol.
From my conversation with Julio over there, he said that there is a "duty cycle" on the pumps, and that typically, the expected lifespan, is between 2-3 years. It was explained that the Methanol somehow degrades the pump's internals over that time span.
Julio actually suggested that I purchase one (additional) pump that's brand new, then ship him back my old one to have rebuilt.
The rebuilt price I paid was under $100 at the time. I can't imagine it's gone up a whole lot since then.
So to date, I am on my 2nd pump. I have my original now, which was rebuilt, and has been sitting on my shelf collecting dust.
So not bad given I've been on the meth train now for approximately four years.
Maybe try giving Alky Controls a call.
Certainly can't hurt..... (813) 265-1400
