Static-impeller driven, which means the pump contains an electronic driver or motor that has no moving parts but simply spins on a magnetic field. The magnetic field grasps the impeller and visibly spins it without any moving parts or seals. As a result, it's extremely long-lived without much power consumption. These pumps are completely brass and stainless steel, so they don't corrode.

The El SID pumps have no seals which can leak, and no bearings to get hot or brushes to spark - they are explosion proof.
