The “Filter-Free” Process

1. Dirty liquid, driven by the circulating pump, enters the separator’s tangential inlet and is directed into a spinning motion.

2. Spinning motion imparts centrifugal force on the solids entrained in the liquid. This centrifugal force throws the debris to the outside wall of the separator.

3. The friction of the flow rubbing against the steel body of the separator creates a “shear layer” of low velocity fluid allowing the debris to fall to the bottom of the separator and through to the debris receptacle.

4. The clean liquid travels through a vortex, out through the center discharge, and back to the tank (or to an optional Trash Can ™ polishing filter).

5. As the debris receptacle fills, the liquid is displaced out of the receptacle, leaving a pack of sludge.

6. When the debris has built to the top of the receptacle, a sensing device illuminates a light indicating that the debris receptacle is full and will need to be emptied soon. Remember though, regardless of when the debris is emptied, it will never interfere with the flow.

7. The gate knife valve between the centrifugal separator and the debris receptacle is manually closed to isolate the debris from the flowing liquid.

8. The hinged closure is then opened and the accumulated debris is dumped into a hopper for disposal.
