Sounds like I have the same motor. I bought a Johnson 12V 6600RPM motor off ebay and also tried the 12V Johnson motor off my Leimbach pump as a test. They both performed almost identical. Labored real bad and pulled 6 or 7 amps (blew a 5A fuse almost immediately). If I remember correctly these Idex micropumps are moving about 5 times as much fluid as a Leimbach with each revolution so I think problem is too much volume. I was going to try a 4:1 gear reduction as next step.
