There are several types of industrial oil skimmers. Choosing one best suited for your application will maximize oil removal while minimizing capital outlay and oil skimmer operating costs. First, define the application in terms of the following characteristics:
Operating Conditions
All oil skimmers have a moving medium, and possibly other parts, immersed in the liquid. The performance and life of the pick-up medium, wiper blades, pulleys, etc. are affected by different conditions. These conditions include temperatures in and out of the liquid, pH of the solution, and the presence of solvents or other reactive chemicals.
Removal Capacity
Oil skimmers usually have an oil removal rate expressed in gallons per hour. The rate varies with oil viscosity, so Abanaki rates skimmers using SAE 30 weight motor oil at 65°F (18°C). When specifying removal capacity, it is better to err on the high side to allow for peaks in the oil influx.
Tank or Sump Characteristics
The location, shape, and capacity of a tank or water impoundment are major factors in choosing the right oil skimmer. Also consider fluctuations in water level, turbulence and possible emulsions. Although oil skimmers do not cause emulsions, they can have trouble removing certain types.
Food Processing Facilities
Removal of vegetable oils, greases, and animal fats from a plant’s wastewater stream reduces the costs of processing and disposal.
Solution: The heart of the system features a patented design grease skimmer. Unlike oil skimmers this system was designed and developed specifically to pick up heavy grease and oil. The Grease Grabber® makes use of the differences in specific gravity and surface tension between grease and water.
Steel Mills/Scale Pits
Most steel mills have scale pits in which grease and heavy oil accumulate. In order to avoid fines from the government and expensive sand bed filters, steel mills must limit the amount of grease in wastewater discharge into the environment. Reclaimed grease and oil can be re-used or used as furnace fuel, avoiding sucker truck disposal costs.
Solution: The Model 8 utilizes a continuous belt and wiper to remove up to 40 gallons of oil per hour from the fluid surface. The unit can be used as a pre-treatment before filtration, and in conjunction with coalescing systems.
Alternative:Grease Grabber

Although designs vary, all oil skimmers rely on specific gravity, surface tension and a moving medium to remove floating oil from a fluid’s surface.
Floating oil and grease cling to skimming media more readily than water, and water has little affinity for the media. This allows skimming media in the shape of the belt, disk, drum, etc. to pass through a fluid surface to pick up floating oil and grease with very little water. This oily material is subsequently removed from the media with wiper blades or pinch rollers.
Oil skimmers offers a simple, dependable and effective solution for removing oil, grease and other hydrocarbons from water and coolant. In some cases, operating an oil skimmer alone can achieve the desired level of water purity. In more demanding applications, oil skimming is a cost-effective means of removing the worst of the oil contamination while protecting more sophisticated methods such as coalescers, membrane filters and chemical processes.
Parts Washers
Floating oils re-contaminate parts as they are removed from a wash tank. Oil skimmers can remove this oil. The benefits of using an oil skimmer are oil-free parts and extended fluid life.
Solution: The stainless steel Mighty Mini is a compact belt skimmer designed for parts washers and machine tool coolant sumps. With its large discharge trough and small operating space, the Mighty Mini fits almost anywhere.
Alternative: Tote It, Model 4, Model 8
Heat Treating
Quench oils that must be removed from heat treated parts can be recaptured for re-use or disposal. The results are lower quench oil costs, prolonged wash water life and lower disposal costs.
Solution: The Tote-It’s patented design is a dependable and effective means of removing free floating oil from water. The single assembly unit can be used in any application where 115 VAC, 60 or 220V, 50 Hz power is available. The Tote-It utilizes a continuous belt and wiper to remove up to 12 gallons of oil per hour from the fluid surface.
Alternative: Model 4, Mighty Mini
