 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 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 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.

Specifications
| Oil Removal Rate: |
32 gph (120 lph) with standard tail pulley.
40 gph (150 lph) with high capacity tail pulley.
(Removal rate is based on 30 weight oil in water.) |
| 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 hp, 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 (See "Belt Selection"
next page.) |
| Belt Material: |
Specifically selected for your application (see Belt Selection
page) |
| Wiper: |
Nitrile standard; CRV optional. Specify wiper
material
based on temperature and fluid compatibility.
(See "Operating Limits.") |
| Mounting 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.
Standard tail pulley: 10 lbs. (4.5 kg).
Optional high capacity tail pulley: 8 lbs. (3.6 kg)
4 ft. corrosion-resistant steel belt: 7 lbs.(3.2 kg)
(belt weight varies according to actual length
specified) |
| Options (Specify): |
- Flat surface mount kit
- Tail pulley cage and tether assembly for
operation in turbulent liquids .
- 3" PVC discharge pipe kit
- Floor mounted support stand.
- 304 stainless steel housing.
- Thermostatically controlled heaters
(115/230VAC, 900 Watts; the heater hood
replaces the standard drive unit cover.)
- Oil Concentrator for virtually water-free oil
(see Abanaki Oil Concentrator on next page.)
- Float switch with signal light ( fits in
3/4" drum bung) to prevent discharge
drum overflow.
