I'm starting to wonder whether there are several versions of the pump in question around... especially as mine, and the CM10P7-1 a.k.a. Jabsco, are described as "ball-bearing permanent magnetic drive". No brushes there.
No mention is made of capacitors, but it says to make sure the motor housing is connected to GND (say, the PC case) and to have a fuse in-line. 1.6 A for the CM10P7-1, and 3 A for the CM30P7-1.
