HOW DOES A SWIMMING ATTRACTION WATER PUMP NOT ELECTRICUTE PEOPLE?

This is accomplished in three main ways.

  1. A system can be designed so the the pump is immersed in the water, but the motor that turns the pump is outside the water. The pump and motor are connected by a shaft.
  2. The pump and motor are submersible however all the electrical components are isolated with materials that do not conduct electricity.
  3. In all cases, pumps used in applications where humans and animals enter the water all have elaborate, ground fault (GFI) technology that immediately shuts off the electricity should the electrical components be subject to the water.
