Included: the motor with its lead; lead length per model is in the Models table.
Pump end required, ordered separately: a Baker pump end of the same horsepower with a NEMA 6 in motor bracket.
Motor control: Single-phase three-wire motors need a control box. Overload protection must be provided by the user.
Drop cable and splice kit: sized to your setting depth and ordered separately.
Baker’s 6 in asynchronous two-pole submersible motors run from 5 to 60 HP, in AISI 304 stainless steel and painted cast iron for the parts in contact with water. A mixture of water and glycol cools and lubricates the Kingsbury-type thrust bearing.
The stator is canned in an airtight stainless steel casing, the squirrel-cage rotor is copper, and the shaft end is Duplex stainless steel. A removable cable connector makes service fast. The motor is suitable for use with a variable frequency drive (60 Hz); overload protection must be provided by the user.
Covered for 3 years from the date of manufacture under A.Y. McDonald’s published terms for Baker submersible motors. The terms add a 5-year term from the date of manufacture for Baker submersible motors, including assembled pumps with pump ends up to 25 GPM, in potable water applications.
One motor per pump end, matched by horsepower. Need more head or flow later? Pair a larger pump end with the matching larger motor: Baker 6 in motors run from 7 1/2 to 15 HP in this listing, all on the same NEMA 6 in flange.
