However I understand from Dave, there are a few people that can not make there 750 work at all, for more then a few weeks.

I believe they maybe using a very restrictive system, or thermol overloading somehow.

I also believe given the low percentage of returns (around 1%) that this can be explained by simple assembly issues. They have also found that the pumps can be damaged in transit, having seem several that where hit so hard, as too have the screws holding the motor on stripped out, one even had the magnetic cap bent (was not disassembled). They have since changed packaging, with additional protection.

The only issue I see, is long term use under very restrictive use or in series, in which case I would suggest a MAG model or another pump designed for high back pressures. This is why AVT is sponsering a low cost upgrade program with C-Systems. We have to do this with C-Systems as our insurance carrier will not let us do so directly. In a free flowing systems, the 750 runs for years, and AVT still produces them for our applications and OEM orders.

C-Systems only produces the MAG model, and the company was purchased just to secure a supply of these units for there own internal use.

I dunno ?
it seemed like everything was explained away in this post,
guess I missed something

one of the luxuries of NOT being a pump mfgr is that I do not have to make excuses about pumps, I replace them and send them back to the mfgr
