A zero maintenance pump includes a motor having a motor housing and a
motor drive shaft rotatably mounted in the motor housing. A shaft
extension is coupled to the motor drive shaft distal from the motor
housing. A coupling element has a body with a first end and a second end
opposite the first end. The body includes a body wall defining an
interior and an exterior. At least one slot is formed in the body wall.
The coupling element includes a flange coupled to the body wall proximate
the first end. The coupling element is coupled to the motor housing at
the flange proximate the motor drive shaft and the coupling element is
disposed over the shaft extension. A mesh element is coupled to the body
wall at the exterior. A pump is coupled to the coupling element proximate
the second end.
