Surface oil belt skimmers from Eriez Hydroflow feature an oleophilic (oil-attracting) belt designed to strip separated oil from both of its sides. This method increases performance and belt life by eliminating contact with a stationary scraper, the company says.
According to the company, reducing tramp oil is a high priority for metalworking shops. Excess tramp oil leads to smoke, mist and bacterial infestation of the metalworking fluids, which adversely affect surface finish and reduce tool and dimensional tolerance control. The oil skimmer can be equipped with a timer so the unit runs only when the machine is idle and tramp oils have risen to the surface. The unit extends coolant and cleaner life, improves machining and preserves tools. It is designed for fast, easy belt changing, and the lower hang roller will not fall off in the machine sump, even in turbulent sump conditions, the company says.
The skimmers are equipped with an impedance-protected, fan-cooled drive motor that features a hardened shaft and needle bearings. The skimmers also include an accessible oil-collecting tray with a drain connector.
