The Abanaki Model 4 Oil Grabber is a dependable and effective means of removing oil from water and water-base solutions. Often, oil skimming by itself will reduce oil to an acceptable level of water purity. Depending on the characteristics of the liquid, it is possible for the Model 4 alone to reduce oil content to less than five parts per million in water. The unit can be used as a pretreatment before filtration, and in conjunction with coalescing systems as part of an industrial wastewater treatment plan.

Model 4 belt oil skimmers utilizes a continuous belt and wiper to remove up to 20 gallons of oil per hour from the fluid surface. The belt, operating on a motor and pulley system, runs through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belt passes through tandem wiper blades where oil is scraped off both sides of the belt and discharged. The tail pulley has flanges which allow it to roll freely on the inside of the belt without becoming dislodged. It requires no bearings and does not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulley from being dislodged.

Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belt to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model 4 can be used in tanks with depths as shallow as one foot, or as deep as 100 feet.

Advantages of Model 4 Belt Oil Skimmers

  • A single unit elevates and separates oil
  • Lifts oil any distance without the need of expensive pumps
  • Maintains oil skimming efficiency with fluctuating fluid levels
  • Can be used in depths as shallow as one foot, or as deep as 100 feet
  • Requires no tank modifications in most applications
  • Operates in turbulent liquid using optional tail pulley cage and tether assembly
  • Easy mounting and fast cleaning, with minimal maintenance

Rugged Construction for Harsh Conditions: The Model 4 oil skimmer is designed to last for many years. With the proper configuration it can handle liquid temperatures up to 212°F, and the pH of the fluid can range from 3 to 13. Belts are specifically selected for your application (see Belt Selection page). The skimmer drive includes an oil filled gear reducer with bronze gears and ball bearings. The motor, reducer, and powder coated finish of the weldments give the Model 4 exceptionally long life, even under the harshest conditions.

Typical Belt Oil Skimmer Applications

The Model 4 is designed for those applications where other models provide excess capacity, or physically will not fit. From a mere shimmer on top of water to a heavy oil slick, the Model 4 performs efficiently, removing up to 20 gallons of oil per hour. Wastewater sumps
