Skimmer
Minimizes Water Pickup Conventional skimmers for removing sludge,
scum and oil from wastewater tanks tend to collect a large amount of water
as well, often necessitating further separation steps. The Gyroskimmer
employs an ingenious design, as one judge characterized it, that relies
on two sets of floats to minimize the pick up of water and ensure reliable
and constant skimming. Four models provide capacities ranging from 4 gpm
to 26.4 gpm and maximum heads from 13 ft. to 23 ft.The Gyroskimmer is
compact, lightweight and easy to set up, even in underground tanks. The
smallest model, the 602GY(P), weighs less than 29 lb., while the largest,
the 1200GY(P), is only 60 lb. The skimmer features a built-in submersible
pump and does not require any other equipment for operation. An optional
motor-driven scraper vane can be added to prevent blockage by sludge or
scum if that is a concern. Each unit consists of sets of outer and inner
floats, a suction gate ring, and a hopper for collection of the waste.
The two sets of floats work independently. Three large outer floats support
the unit, including the hopper and hoses, while three inner floats maintain
the suction gate at water level regardless of waves, preventing suction
drag. The shape of the floats keeps them from interfering with intake
and the curved surface of the suction gate impedes air from entering.
The suction gate is vertically adjustable, to a depth of 0.28 in. to 0.39
in., depending upon model, to accommodate surface layers of different
thickness.
Made of stainless
steel and polypropylene, the Gyroskimmer resists corrosion and handles
temperatures up to 104?F. The 602GY(P) model has a discharge diameter
of 1 in., while 800GY(P) and 1000GY(P) have 1.5-in. diameters and the
1200GY(P) has a 2-in. diameter.
