TR-517 F.A.P. Plus™ Skimmer, 36-inch travel | DGSI Slope Indicator Environmental Products
Min. depth of 24 inches from bottom of well to product/water interface required
- The skimmer is attached to the bottom of the F.A.P. Plus™ pump and is used to separate the product from the water in the well.
- The skimmer is a necessary part of the F.A.P. Plus and F.A.P. Plus ZW pumps and must be ordered separately.
- Depending on your site conditions, three types of skimmers are available: standard, high-viscosity, and density.
Note: Density skimmers are not compatible with the F.A.P. Plus ZW. To use a density skimmer, you can either purchase a conversion kit (TR-51699) or you can purchase the F.A.P. Plus pump (TR-516).
The standard skimmer is used to recover gasoline, jet fuel and most diesel fuels. It combines a TR-57-17 Skimmerdensity float, a special hydrophobic element, a product bypass, a hollow guide rod and a coiled hose.
The center guide rod allows the skimmer to travel freely in response to the water table changes. The skimmer is designed to float with the inlet positioned at the water/product interface automatically providing 36” of skimmer travel. The density float is used to position the special hydrophobic element — the skimmer inlet — at the product water interface. The hydrophobic element uses a special micron pore size that is based on surface tension, allowing only product to pass. A larger pore size is available for use with higher viscosity products such as weathered diesel.
Pumping rates through the hydrophobic element will be approximately 100 gallons per day. Tech Tip: The larger micron-sized elements may allow a small percentage of water to pass. The bypass element is attached to the top of the hydrophobic element and allows the product to enter the skimmer directly when the product layer is greater than 2 inches. Recovery rates through the bypass element are approximately 300 gallons per day. The complete skimmer element is connected to the bottom of the guide rod by a coiled polyurethane hose. This coiled hose can accommodate water level changes of up to 36 in automatically maintaining the skimmer intake at the water/product interface.
A minimum distance of 24 in from the bottom of the well to the water/product interface is required when using the TR-517. The TR-51711 requires a minimum of 18 in and provides 24 in of travel. The skimmer can also be configured as a passive device by attaching a quick connect canister on the bottom of the skimmer, providing greater flexibility for free product recovery projects.
Maintenance: Biofouling may occur because the hydrophobic element is positioned at the air/product interface. If fouling occurs, the element can be cleaned using a soft brush or replaced by unthreading the bypass element and installing a new hydrophobic element.
