Are you sure Cathar?
AFAIK (from the CM series datasheet) the CM30P7-1 has a ball bearing permanent magnet motor.
Permanent magnet motors by conception are brushless...
This is one of the two big differences between the CO30 and the CM30 series (beneath the direct driven vs mag driven impeller).
Couldn't find any number for the MTBF although.
BTW, these Laing pumps look promising, what about availability and pricing?
