Flojet 20115-220 End Bell Kit, Copper Brush
The Flojet 20115-220 is the genuine copper brush end bell kit for Flojet pump motors. It replaces the whole non-drive end of the motor as one assembly: the housing, the brush gear and the rear bearing support together.
Replacing the assembly rather than individual pieces is the sensible approach on a motor that has done real work, because the components in it wear as a system. Brushes shorten, their springs relax, the holders develop clearance, and the bearing seat loses its grip — and each of those makes the others worse. A brush that rocks in a worn holder sparks; sparking pits the commutator; a pitted commutator eats the next set of brushes faster. Renewing the whole end bell breaks that cycle rather than treating one symptom of it.
Copper brushes identify this as the specification for low-voltage, high-current motors, where plain carbon would waste too much energy as heat and voltage drop. Because brush grade and bearing type are both specific to the motor, confirm the part number against the parts breakdown for your pump before ordering rather than matching by appearance.

Frequently Asked Questions
Q: Why do worn brush holders cause sparking?
Because a brush with clearance around it rocks instead of sitting flat on the commutator. Contact becomes intermittent, and every break in contact is a small arc.
Q: Does sparking damage the motor?
Over time, yes. Arcing pits the commutator segments, and a pitted commutator wears brushes rapidly and conducts less well, so the problem accelerates.
Q: Can I clean a pitted commutator instead?
Light cleaning can help a marginal case, but genuine pitting needs machining, which is rarely practical on a small pump motor. Replacing the wear items before it gets that far is the better plan.
Q: How do I match the right end bell?
By the parts breakdown for your pump model rather than by appearance. Brush grade and bearing type both vary between otherwise similar-looking motors.
