The TRUE zero-water, product-only recovery system
Groundwater remediation pump with "Zero Water" pneumatic logic and AccuPos™ indicator.
- LNAPL and DNAPL recovery.
- Recovery of a wide range of products from light-end hydrocarbons with SSU values of 80 or lower, such as gasoline, diesel fuel, hydraulic fluids, to more viscous products like #6 heating oils. For recovering products with higher viscosities, the F.A.P. Plus™ may be used with our high-viscosity rod skimmers or our density skimmers.
- 2" or larger wells.
The F.A.P. Plus™ ZW groundwater remediation pump (TR-51640) consists of a flexible, special inner bladder and a flexible Buna-N® hose which forms the outer pump body. The pump operates by alternately inflating and deflating the annular space between the inner bladder and the outer hose. When compressed air is applied, the inner bladder collapses. When the air is exhausted, the inner bladder rebounds to its original shape thereby causing a suction which pulls fluid into the pump and up to the surface. The pump is capable of producing a suction of 17 inches of mercury for the recovery of viscous product and operation in deep wells up to 200 feet.
F.A.P. Plus™ ZW is an upgraded version of the basic F.A.P. Plus™ pump. The ZW model incorporates the “Zero Water” pneumatic logic that stops and starts the F.A.P. Plus™ ZW automatically — depending on the position of the skimmer inlet — and prevents the ingress of water when the water level rises more than the skimmer travel allows. The AccuPos™ Indicator helps locate the product/water interface level accurately which makes it easy to install the pump at the correct depth.
The F.A.P. Plus™ ZW remediation pump system comprises seven main components:
F.A.P. Plus™ ZW pump
F.A.P. Plus Skimmer, 36" travel (min. 24" travel required)
|TR-51718||F.A.P. Plus Skimmer, 18" travel (min. 18" travel required)|
|TR-51711||F.A.P. Plus Skimmer, 24" travel (min. 18" travel required)|
This skimmer is used when the product has a viscosity higher than 80 SSU, such as oils. The 4 in high viscosity skimmer uses the same design as the TR-517, less the hydrophobic and bypass elements. The skimmer has a 30 in travel and a specific gravity of 0.95, allowing it to float at the water/ product interface. The product collects on the top of the skimmer inlet and, from there, is pumped to the surface. In normal applications the skimmer will remove product down to a ¼ in to ½ in product layer. The skimmer can be adjusted in the field to remove the product even further and attain a thinner layer.
4" High Viscosity Rod Skimmer (30" travel)
Density skimmers are used when there is less than 18 inches of fluid from the bottom of the well to the water/product interface. These skimmers have a specific gravity of 0.95 and float in the water with the top inlet just above the product/water interface. The skimmers have an effective travel of 24 inches. The 2 in and 4 in sizes are for use in well casings with these nominal inside diameters. The 6 in and 12 in models are self-supporting and may be used in large diameter wells, open excavations and open water applications.
|TR-702||2'' Density Skimmer (1.65" dia.)|
|TR-704||4'' Density Skimmer (3.5" dia.)|
|TR-706||6'' Density Skimmer (5.5" dia.)|
|TR-712||12" Density Skimmer (11.5" dia.)|
Important elements in choosing a F.A.P. Plus ZW™ system are:
- Water table fluctuations
- Product viscosity
- Type of product
- Well diameter
- Amount of product present
- Depth from bottom of well to product/water interface
The Well Clincher or cap has expandable, pass through fittings for the air supply tube and product discharge hose, allowing the pump depth to be easily adjusted. The Well Clincher fits over and seals the casing to prevent foreign materials entering the well. Standard sizes available for 2 in to 8 in well casings, custom sizes available upon request.
|TR-762||2'' Well Clincher for F.A.P. Plus|
|TR-764||4'' Well Clincher for F.A.P. Plus|
|TR-766||6'' Well Clincher for F.A.P. Plus|
|TR-768||8'' Well Clincher for F.A.P. Plus|
Pneumatic Overfill Protection Device
Tank-Full Shut-Off (Pneumatic)Shuts off fluid supply to remediation tanks when full.
Application:This pneumatic device is activated by a high liquid level in the recovery tank. Once activated, it shuts the air supply to the pneumatic pump, stopping fluid discharge to the tank.

|Note 1: The use of synthetic oil in an air compressor can cause chemical deterioration of components In the Control Valve that could result in failure of the unit.|
|Note 2: The TR- 75713 can support up to six FAP+ZW skimmer pumps. Consult with a factory representative before using a larger number.|
|Note 3: If the unit must be operated in temperatures less than 33°F., then a desiccant air dryer must be used to reduce the dew point of the moisture in the compressed gas to a lower temperature than ambient. If using inert compressed gas, check with the supplier concerning the dew point temperature of the inert gas supplier.|
|TR-75713||Tank-Full Shut-Off (pneumatic)|
The 5-micron coalescing and auto-drain device is used to filter compressed air to operate the pump. An element indicator provides a visual indication when the filter elements need to be serviced. The regulator allows the pump operating pressure to be set according to the depth of the pump.
