The TRUE zero-water, product-only recovery system
Operation
Groundwater remediation pump with "Zero Water" pneumatic logic and AccuPos™ indicator.
Remediation Applications
- 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.


Operation
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.
Description
The F.A.P. Plus™ ZW remediation pump system comprises seven main components:

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.SPECIFICATIONS FOR THE TR-75713 PNEUMATIC TANK-FULL SHUT-OFF | |
Enclosure | PVC and 6061 aluminum |
Chemical Compatibility, Exterior Components | Refined petroleum products |
Compressed Gas Supply | 0 to 100 psi, filtered to 40 microns (see note 1) |
Compressed Gas Consumption | 0 scfm |
Control Valve | 2 way, normally open, 20 scfm @ 100 psi (see note 2) |
Operating Temperature | 33 to 120°F. (see note 3) |
Compressed Gas Connections | Primary ¼” O.D. push-to-connect tubing fittings. Secondary ¼” female NPT on bulk heads |
Operation Status Indicator | Pressure indicator colorimetric, “Green” compressed gas is supplied to pumps, “Black” compressed gas is shut off to pump(s) |
Reset After Shut Down | Manually operated |
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. |

Filter/Regulator Assembly
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.
