A new design belt skimmer by Keller Products Inc. eliminates skimmer discard pail overflow and permits virtually 100 percent tramp oil discard with no loss of coolant, while continuously recycling clean coolant to the sump. In contrast to conventional belt skimmers, which attempt unsuccessfully to lift primarily tramp oil, the new "Black Magic"
skimmer directs all the fluid from the belt skimmer to a separation vessel, where the tramp oil is held for discard and the clean coolant returns to the sump, according to the company.

The new belt skimmer is easily mounted on the sump cover with a magnetic mount. The skimmer mounting bracket permits adjusting the height of the skimmer to access the sump. The collected tramp oil may be occasionally drained or poured from the separation vessel into a waste tramp oil container. No other operator attention is required.
