This wet-rotor pump utilizes an epoxy-encapsulated motor and plastic housing. A permanent magnet is attached to the impeller. The magnet acts as the rotor would in a conventional motor. The water being pumped surrounds the rotor, thus the term "wet-rotor". It is seal-less and oil-less. This pump works well in water garden, statuary and some industrial applications. It is compact in design and is the most energy efficient type of pump Little Giant manufactures.
