Hi Dave, That's funny. I am an engineer but opinions and others' expertise are always welcome. That is how I learn. I found some inexpensive HPLC pumps on ebay but most are sold as-is. You don't know if the seals are any good and if some yahoo like me tried to push solder paste through it...well who knows what shape the pump is in.
I do have a larger pump I purchased from the 3M surplus store in St. Paul, MN. The pump is a screw piston type and is rated to somewhere near 30,000 PSI. The assembly had a bunch of high pressure proportional valves and stainless tubing. The pump cylinder is probably 5 cubic inches. Quite large for a solder paste dispenser. I have not looked into HP's paint heads. Sounds interesting because one would think the paint media is a bit thicker than ink. The older inkjet heads won't work because the ones I'm familiar with heat up a small thin film resistor to boil a spec of ink and this heated ink blows through a small orifice to the paper. If I boiled solder paste I would have boiled solder paste. Eventually I will find something that will work. This is the idea kicking phase at the moment.
