Salvage....
...all the Flojets I've tested all run deadheaded ok. They'll run up to their individual max pressure then just sorta chug along. I can't remember the exact current draw but it was on the low side, say maybe 11 or 12.
If you want a nice pump, money no object, get the one from Carrolls Supercharging out of NJ. 973/835-1705. They call it a "high pressure water injection pump", and the only part # I could dig up is A25011. As far as I can tell, this is a custom built, older style, dual chamber Flojet. It can be ordered with any one of 5 cam drives, which increase pressure. I use the next-to-lowest pressure cam, rated for 1.66 GPM (a 1.15 is standard, a 2.35 the highest). This delivers around 85lbs at a sustained flow through four, 1.0mm nozzles, at about 8 amps.
