Pools are usually loaded with residual electrical current. This phenomenon is amplified when a salt water chlorinator is used.

  • If the pool is not earthed, the difference in potential between the pool and surrounding earth may cause damage to the pump (faster wear of bearings and pump mechanical seal due to the passing current).
  • Thanks to a stainless steel plug, certified by Dekra, this current is evacuated towards the motor casing without touching the rotor shaft or bearings.
