There are pumps available in the photo-finishing world that could work
for us. The pumps on the Noritsu machines are 12V magnetically coupled
plastic head devices with a head that can be disassembled and cleaned
out. If they can stand the chemicals in photo-finishing then coolant
won't even touch them.
