Section 1: System Description
Function and Theory
The Geotech Guzzler, when used in conjunction with a down well intake, efficiently
collects free-floating hydrocarbons and other fluids in 2” (5 cm) or larger recovery wells.
Designed for shallow well applications, the pump pulls fluid from up to 25’ (7.6 m) and
requires no electricity for the controls.
The system consists of a Pneumatic Dual Diaphragm Pump, Tankfull Shut-off Valve, Air
Regulator, and user controls secured in a stainless steel enclosure. The Guzzler can be
attached to a Skimmer with floating intake cartridge or Total Fluids Intake, and a Tankfull
Shut-off Sensor tube.
The Guzzler’s Dual Diaphragm Pump creates a vacuum, drawing product from the down
well intake and discharges it into a recovery tank (not included with system). The Guzzler
requires 6 SCFM (.17 SCMM) minimum of air pressure at 45 PSI (3 bar) in order to
operate.
Geotech Skimmer intakes are designed to efficiently collect free-floating hydrocarbons in
2” (5cm) or larger recover wells. The Skimmer’s buoy follows the water table fluctuations
and places an oleophilic screen at the water/product interface, skimming LNAPL (light,
non-aqueous phase liquid) down to a sheen within the range of the float travel. As the
system cycles, product is drawn through the intake screen and transferred to the pump
through a coiled hose and the Skimmer’s transfer shaft. Optional Heavy Oil and High
Temperature Skimmers are also available and can recover product in 4” (10 cm) diameter
and larger wells.
For total fluids recovery applications, the Total Fluids Intake can be deployed up to 25’
(7.6 m) depth to fluid and pumps all fluids through a screened intake. When installed with
an automatic Level Control Valve, the Total-Fluids Intake will automatically pump or
standby depending on fluid level in the well.
When installed to the Guzzler Control Box and a recovery tank, the Guzzler’s Tankfull
Shut-off valve shuts off the pump when the recovery tank becomes full.
Specific Gravity and Viscosity Limitations
The specific gravity of the product to be recovered must be less than 1.0 and its viscosity
less than 50 SSU for use with the “light” oil filter, and 400 SSU for use with the “heavy”oil
filter cartridge. Consult Geotech for product recovery operations with viscosities outside
that range.
This type of filter and recovery technology is designed to be used in wells with free-floating
product of at least 1/8” (3 mm) thickness.
The presence of surfactants or detergents in the product requires careful application.
When handling these contaminants please consult Geotech.
