Abstract
Embodiments of the disclosure provide a booster pump to pressurize fluid for use by a pool cleaner in a pool or spa. The booster pump includes a front housing having an inlet, a plurality of diffuser units positioned in the front housing, and a motor housing detachably coupled to the front housing and having an outlet. A submersible motor positioned in the motor housing is operatively coupled to the diffuser units. A space is defined between an outer surface of the motor and an interior surface of the motor housing. A self-contained fluid flow path is formed from the inlet, through the diffuser units, and through the space to the outlet. As the fluid passes over the motor, the motor can be cooled and acoustic output of the booster pump can be dampened. The booster pump can be constructed of plastic for applications in the pool and spa industry.
