The Abanaki Model MB Oil Grabber is a dependable and effective means of removing oil from water and water-base solutions. Often, 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 MB 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 a coalescing system.
The Model MB utilizes continuous belts and wipers to remove up to 200 gallons of oil per hour from the fluid surface. The belts, operating on a motor and pulley system, run through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belts pass through tandem wiper blades where oil is scraped off both sides of each belt and discharged. The tail pulleys have flanges which allow them to roll freely on the inside of the belts without becoming dislodged. These lower pulleys require no bearings and do not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulleys 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 belts to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model MB can be used in tanks with depths as shallow as one foot or as deep as 100 feet.
Advantages
- A single unit elevates and separates oil
- Lifts oil any distance without the need of expensive pumps
- Maintains skimming efficiency with fluctuating fluid level
- 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 MB is designed to last for many years. With the proper configuration it can handle liquid temperatures up to 212 ½F, and the pH of the fluid can range from 1 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 the Model MB exceptionally long life, even under the harshest conditions.
Typical Applications
The Model MB is designed for those applications where other skimmers do not provide adequate removal capacity. Multiples of two, three, or five belts are available. From a mere shimmer on top of water to a heavy oil slick, the Model MB performs efficiently, removing up to 200 gallons of oil per hour.

*Removal Rate is based on 30 weight oil in water and standard Polymer belt |
Removal Rate: |
(See Table) |
Tail Pulley: |
Specify standard or high capacity. (The high capacity option uses a patented pulley design that improves the adherence of oil to the inside of the belt, thus increasing the removal rate.) |
Motor: |
Fractional, TEFC, gear motor operating on either 115/230VAC, single phase, 60Hz or 230/460 VAC, three phase, 60Hz. Optional: 50Hz power source; explosion proof; drip proof; pneumatic; and wash down duty motors. |
Belt Width: |
8 in. (20 cm) |
Belt Length: |
User specified (up to 100', measured from the center of head pulley to center of tail pulley) |
Belt Material: |
Specifically selected for your application (see Belt Selection page) |
Wiper: |
Nitrile standard; UHM, Ceramic or CRV optional. Specify wiper material based on temperature and fluid compatibility. (See "Operating Limits.") |
Mounting Method: |
For MB 2x8 and 3x8 Bracket for 5" steel channel (supplied by customer), with oil discharge through the channel. For MB 5x8 Bracket for 5"square tube (supplied by customer), with oil discharge through the channel.

Weights1: |
Drive assembly and housing with motor, without belts or tail pulleys: 2 belt unit: 74 lbs. (34 kg) max. 3 belt unit: 86 lbs. (39 kg) max. 5 belt unit: 110 lbs. (50 kg) max. Tail pulley (per belt): 10 lbs. (4.5 kg) 4 ft. corrosion-resistant steel belt: 7 lbs.(3.2 kg) (belt weight varies according to actual length specified) |
Options (Specify): |
- Tail pulley cage and tether assembly for operation in turbulent liquids.
