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.

Section 2: System Components
Guzzler Control Box
Diaphragm Pump
The Guzzler utilizes an air driven Dual Diaphragm Pump secured in a steel enclosure for
protection. The Pump Intake, Pump Discharge, Tankfull Sensor, and Air-In ports of the
pump are pre-plumbed to fittings attached to the exterior of the enclosure. Exterior fluid
fitting hose barbs come standard to fit 3/8” (9.5 mm) ID tubing. Air Supply Input connects
with an industrial 1/4" coupling plug and socket fittings. Additional information for pump
service recommendation and instructions are provided in the Manufacturer’s Service and
Operating Manual for the pump.
Air Regulator
Each Guzzler includes a built-in Air Regulator with a filter and pressure gauge, and an AIR
ON/OFF switch. The Air Regulator controls operating pressure, removes particles and
liquids in the air stream, and has an automatic drain plumbed to the bottom of the control
box. See Figure 2-1.
When initially applying air to the pump, the air pressure must be regulated down to 30 PSI
(2 bar) in order for the Dual Diaphragm Pump to prime. The air requirements for the
system will vary with the operating speed of the pump. As the pumping rate increases, the
airflow requirement increases. At maximum speed, the pump requires 6 SCFM (.17
SCMM) of air. During normal operation, the Guzzler uses approximately 2 SCFM (.05
SCMM) to 4 SCFM (.11 SCMM) of air. In freezing conditions, adding an additional air
dryer to the system inlet may be needed to avoid stalling the pump.

Down well Intakes: Skimmers and Total Fluids
Skimmer Attachments
A standard Skimmer attachment can be used in either 2” (5 cm) diameter or 4” (10 cm)
diameter and larger wells. Figure 2-2 shows an example of the two most common
Geotech Skimmers. These Skimmers come with a standard 100-mesh intake screen. A
60-mesh intake screen is also available for use with higher viscosity fluids. See Geotech
Manual “Hydrocarbon Viscosity Test Kit” for more information on choosing the correct
intake cartridge.
Figure 2-2: Standard 2” and 4” Skimmer Attachments
The Skimmer assembly discharge line attaches to the PUMP INTAKE hose barb on the
Guzzler Control Box. The Skimmer consists of a product intake float, a coiled product
transfer hose, and a transfer shaft. Well centralizers are positioned at the top and bottom
of the Skimmer shaft to protect the intake float and to allow unobstructed travel within the
well. Standard Skimmers can provide 12” (30 cm) to 24” (61 cm) of intake travel. Geotech
can provide up to an extended 5’ (1.5 m) of travel (4” Skimmers only) on a custom order
basis. A Skimmer assembly will not draw water unless the intake cartridge is
forcibly submerged, surfactants are present, or when the “conditioning”
of the intake screen is removed. See Section 5: System Maintenance
for information on reconditioning the intake.

Heavy Oil Skimmer Attachment
The optional Heavy Oil Skimmer attachment is designed to recover a range of fluids from
gasoline to gear oil, skimming the product down to .01’ (3 mm) in 4” (10 cm) diameter and
larger wells. This option is best suited when the viscosity of the hydrocarbon is greater
than the capability of the filter screen technology (screen can no longer pass the
hydrocarbon fluid).
The Heavy Oil Skimmer consists of a polypropylene intake buoy, a coiled product transfer
hose, and a transfer shaft with well centralizers placed at the top and bottom. The intake
buoy on the Heavy Oil Skimmer is designed to “ride” at the oil water interface and has a
travel range of 24” (61 cm).
The intake buoy can also be “fine-tuned” by adjusting the intake fitting on the top of the
buoy. Turning the fitting clockwise will lower the intake fitting relative to the product/water
interface. Turning the fitting counter-clockwise will raise the intake fitting away from the
interface. Figure 2-3 is an example of a Heavy Oil Skimmer assembly.

High Temperature, Heavy Oil Skimmer Attachment
For high temperature well environments, Geotech provides a High Temperature, Heavy
Oil (HTHO) Skimmer that incorporates an ultra-high molecular weight (UHMW)
polyethylene intake buoy. The HTHO Skimmer has stainless steel end caps placed at the
top and bottom of a stainless steel screen to keep out debris. The intake buoy of the
HTHO Skimmer has a travel range of 26” (66 cm).
Like the Heavy Oil Skimmer, the intake buoy can be “fine-tuned” by adjusting the intake
fitting on the top of the buoy. Turning the fitting clockwise will lower the intake fitting
relative to the product/water interface. Turning the fitting counter-clockwise will raise the
intake fitting away from the interface. Figure 2-4 is an example of the High Temperature,
Heavy Oil Skimmer.
Figure 2-4: High Temp, Heavy Oil Skimmer Attachment (optional)

Total Fluids System
The Total Fluids System consists of a Level Control Valve, a Total Fluids Intake, and 50’
of sensor airline. The Level Control Valve is mounted directly onto the Guzzler Control
Box at the AIR SUPPLY INPUT quick connect. Figure 2-5 shows an example of how the
Total Fluids System connects to the Guzzler.
The Total Fluids Intake pumps all product down to approximately 2.5” (6.35cm). When
used with the Level Control Valve the Total Fluids Intake will turn off when the fluid level is
2.5” (6.35cm) from the screened intake and resume operation when the fluid level is 4” (10
cm) above the screened intake. If the Total Fluids Intake is used without the Level Control
Valve, the pump will continue to run even in the absence of fluid.
