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.
