Spacer Cans

Spacer Cans

A spacer can is a non-contact component used in sealless magnetic drive pumps. It houses the internal rotor assembly and isolates it from the external magnet assembly. Traditional spacer cans made from stainless steel or Hastelloy are prone to eddy current generation, which reduces pump efficiency and causes heat buildup.

Ceramic spacer cans, in contrast, offer a non-metallic solution, effectively eliminating eddy currents and increasing system efficiency.
