The MCS-500’s magnetically coupled actuation eliminates the need for dynamic seals. This technology provides quick and easy access for maintenance, reduces potential leaks, and requires few moving parts while providing a long service life.

The High Flow MCS-500 is engineered specifically to help conserve valuable process water while protecting costly processing equipment from debris.

Featuring fast cleaning magnetically coupled actuation, the design offers an optimized configuration to help improve and reduce costly maintenance and down time. In addition, this actuation method eliminates the need for lid-thru holes and their associated seals.

Designed to handle fresh water from treated sources, the High Flow MCS-500 addresses the challenges water filtration can bring to industrial manufacturing.
