The
Abanaki Model 8 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 8 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.
The Model 8 utilizes a continuous
belt and wiper to remove up to 40 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
8 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 8 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 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 Model 8 exceptionally long life,
even under the harshest conditions.
Typical
Applications
The Model 8 is the most widely
used Abanaki skimmer. Its size and removal capacity make it suitable
for most applications. From a mere shimmer on top of water to
a heavy oil slick, the Model 8 performs efficiently, removing
up to 40 gallons of oil per hour.

Method: |
Standard: Bracket for customer-supplied
steel channel,
with oil discharge through the channel.
Option: Flat surface mount with oil discharge through a
3 in (7.5 cm) NPT male pipe fitting. |
| Weights
1: |
Drive assembly and housing
with motor, without belt or
tail pulley: 82 lbs. (37 kg) max.
