Abstract: A pedicure spa or hydrotherapy system for circulating fluid which includes a motor coupled magnetically with an impeller assembly on the wall of the pedicure spa or hydrotherapy system is disclosed. The system is designed to have low energy consumption and an ultra low profile while at the same time providing a pipeless water circulation that is easy to operate and clean. In addition, the invention minimizes the growth of bacteria within the pumping system as the impeller assembly is easily removed from the wall for cleaning without any mechanical aids. In certain embodiments, the magnetic propulsion and coupling device includes a multi-directional combination of strategically placed and alternating-pole magnets on magnet plates and additional magnets in the housing.

Abstract: A powered pipeless circulation system for a container holding a fluid includes first and second motor assemblies. The first motor assembly has multiple coil members. Each coil member is electrically charged for generating a magnetic field. A first housing is configured for accommodating the first motor assembly, and fixedly attached to a dry surface of a wall of the container. A second motor assembly has at least one impeller and an impeller magnet plate. A second housing is configured for rotatably accommodating the second motor assembly and being disposed on a wet surface of the wall opposite the first housing. The impeller magnet plate is aligned to magnetically engage with the coil members. In use, the second motor assembly is magnetically coupled to the first motor assembly having a wall in-between the assemblies for forming a motor configured for rotating the impeller.

Abstract: A spa, whirlpool or hot tub hydrotherapy system comprised of a unitized pump and motor assembly to provide a pipeless water circulation and air injection system that is easy to clean. The system can optionally provide an ionization device, which injects a stream of silver, copper and zinc ions into the water to kill bacteria, mold and algae, and solid-state lighting.
