MCF Sealless Self Cleaning Filter System

Eaton MCF-824 self cleaning filter

The MCF-824 is a revolutionary automatic strainer design using rare earth magnets to drive the cleaning disc through the element, thus eliminating external shaft and drive seals.  Overall, the MCF-824 has only (2) wear parts, increasing its' reliability and keeping operating costs to a minimum.

 

Fluid flows into the top and down through the center of the strainer element, passes through it and exits out the bottom side.  As material collects within the ID of the strainer element, a spring loaded cleaning disc travels the length of the element pushing this material towards the bottom of the housing into the purge chamber, where the concentrated solids are easily flushed in a matter of seconds when the purge valve is opened. The quartered and spring loaded cleaning disc is designed to ensure even and consistent force against the element to maximize cleaning efficiency.

 

The hollow shaft at the center of the system contains rare earth magnets, an internal magnet is coupled to an external magnet.  Pneumatic actuation from standard shop compressed air injected through the base of the center column pushes the internal magnet up and down.  The outer magnet within the cleaning disc follows the internal magnet.  Thus this patented design eliminates physical linkage passing through the vessel.

 

The cost for an MCF-824 ranges from $27,000 to $35,000 depending upon the degree of automation required. The base system has a "push button" control of a pneumatically actuated purge valve whereas fully automated system can include either Allen-Bradley or Siemens PLC controllers.  Please fill-out our inquiry form which will prompt you for the design criteria required to issue you a detailed  quotation.
