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.
Figure 2-1: Guzzler Control Box Components

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.

6
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.
Figure 2-3: Heavy Oil Skimmer Attachment (optional)

7
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)

8
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.
Figure 2-5: Example of a Total Fluids System

9
Tankfull Shut-off Sensor Tube
The Tankfull Shut-off Sensor assembly consists of a PVC or Stainless Steel sensor
installed to a 2” NPT bung opening in a recovery tank and connects to the Guzzler Control
Box’s TANKFULL SHUTOFF input with a 1/4” OD sensor airline. The recovery tank with
the Tankfull Shut-off Sensor tube installed must be within 50’ (15 m) of the Guzzler
Control Box.
As the tank fills, pressure created in the Tankfull Shut-off Sensor tube by the rising
product is transmitted to the Tankfull Shut-off Valve. The Tankfull Shut-off Valve will
activate when the product level has risen approximately 11” (28 cm) up the Tankfull Shut-
off Sensor tube, shutting off the air supply to the pump. When the recovery tank is
drained, a manual reset on the Guzzler Control Box is required to resume operation.
Figure 2-6: Example of the Tankfull Shut-off Sensor tube shown with a 55-gallon recovery
tank. (Recovery tank not supplied)

10
Accessories
Air Compressor (not provided with the Guzzler system)
Refer to instructions provided with the air compressor for installation procedures. An
automatic tank drain and an air dryer may be required for the air compressor if the system
is operating in humid conditions. Bottled air may be used to operate the Guzzler if
operating an air compressor is not feasible. A high-pressure regulator must be used to
reduce the air pressure to the range of 45 PSI (.06 bar) to 100 PSI (7 bar).
Product Recovery Tank (optionally provided with the Guzzler)
A product recovery tank with a 2” NPT bung opening for the Tankfull Shut-off Sensor tube,
a product inlet opening, and a vent are required for proper operation –typically a 55 gallon
(208 liter) drum or other suitable container (See Figure 2-6). Check government
regulations regarding fuel storage before selecting a recovery tank.
Ensure air compressor is well protected. If placing the
compressor in an enclosure, it must be well ventilated and a fan
may be required for proper cooling. Refer to air compressor user
manual for general guidelines.

11
Section 3: System Installation
Planning Guidelines
To install the Guzzler, use the following guidelines to determine a suitable location for the
air compressor, Guzzler Control Box, down well intakes, and product recovery tank.
The Standard Guzzler does not include an air source. The air source/compressor
must supply 6 CFM (170 LFM) at 45 PSI (bar) minimum.
oDo not locate the compressor in areas where there may be explosive
vapors. Compliance with Section 5 of the U.S. National Electric Code
Handbook and any local codes is essential for an electrically safe
installation. The compressor requires a cool, well-ventilated environment to
operate efficiently, and may require an air dryer in freezing or humid
environments.
Mount the Guzzler Control Box at the wellhead, or as close to the wellhead as
possible.
oThe Guzzler Control Box must be mounted upright in order for it to operate.
The product recovery tank should be located within 50’ (15 m) of the Guzzler Control
Box when the Tankfull Shut-off Sensor tube is used.
Run all air and pump tubing through pipe or conduit to protect them from damage. All
air and discharge tubes must be installed correctly for the system to operate properly.
The cut ends of the tubing must be straight and the connections leak free. Use
clamps for tubing to hose barb connections whenever possible.
Air Line Preparation
Place the Guzzler Control Box, discharge tank, and air compressor in a suitable location
as outlined in the Planning Guidelines.
Calculate the tubing lengths required to install the Skimmer or Total Fluids Intake.
Down well tubing lengths cannot exceed 25’ (7.6 m).
To calculate the amount of discharge tubing required:
oMeasure the static water depth in the well using a Geotech Interface
Probe.
oMeasure the distance between the wellhead and the Guzzler Control
Box.
Because site requirements vary, customers must supply all mounting
hardware for the Guzzler Control Box.
Confirm all measurements before making any cuts to the tubing.

12
oMeasure the distance between the Guzzler Control Box and the product
recovery tank.
Installation
For systems using a well cap:
1. Remove the inner ring of the well cap, and secure it to the well casing using the
three (3) setscrews located on the perimeter of the ring.
2. Pull the measured lengths of discharge tubing through the fitting on the well cap
(when applicable).
3. Attach the discharge tubing from the down well Skimmer or Total Fluids Intake to
the Guzzler Control Box hose barb labeled PUMP INTAKE.
4. Place the Skimmer assembly into the well so that the midpoint of the intake float
travel lies on the static water level measured.
5. Place the Total Fluids Intake at the desired depth for pumping.
6. Attach tubing from the Guzzler Control Box hose barb labeled PUMP
DISCHARGE to the product recovery tank.
7. Install the Tankfull Shut-off Sensor tube in a 2” NPT bung opening on your
recovery tank.
8. Adjust the position of the Tankfull Shut-off Sensor tube so that 12” (30 cm) to 13”
(33 cm) of the tube is within the tank.
When the fluid level reaches approximately 11” (28 cm) on the sensor tube
side, the Tankfull Shut-off Valve will activate to shut off the pump.
9. Attach tubing from Tankfull Shut-off Sensor tube to the Guzzler Control Box tube
connector labeled TANKFULL SENSOR.
10. Open the front panel, locate the AIR ON/OFF switch, and ensure it is in the AIR
OFF position prior to connecting air source.
11. If using a Total Fluids Intake with Level Control Valve, install the Level Control
Valve on the quick connect fitting labeled AIR SUPPLY INPUT.
12. Connect air source to the AIR SUPPLY INPUT (or on the Level Control Valve)
quick connect fitting.
The air source must be less than 100 PSI (7 bar).
The well cap is designed to suspend the intake assembly by the hose. It is
recommended to deploy a safety cable in addition to the tubing for the
heavier, stainless steel screened Skimmers and HTHO Skimmers.

13
Section 4: System Operation
Adjust the Pumping Rate
1. Inside the Control Box, locate the Air Regulator. Pull up on the Air Regulator
adjustment knob to unlock. Rotate adjustment knob counter-clockwise until
loose before putting the switch into the AIR ON position.
2. With the AIR ON/OFF switch in the AIR ON position, slowly turn the Air
Regulator knob clockwise until the pump begins to cycle (around 30 PSI/2
bar). Allow 20 seconds for the pump to prime before adjusting to desired air
pressure, recommended 45 PSI/3 bar.
The Guzzler requires only compressed air to operate. All units will be sent with the AIR
ON/OFF switch in the OFF position. Required pressure will vary depending on site
conditions. The fastest pumping rate possible on the system varies according to pumping
depth, distance from the pump to the product recovery tank, and the product layer
thickness. The Regulator Adjustment Knob is located inside the Guzzler Control Box (See
Figure 2-1). The Air Regulator adjusts by rotating the Regulator Adjustment Knob counter-
clockwise to decrease the pressure rate, and clockwise to increase the pressure rate.
The internal Air Regulator is equipped with an auto-draining filter that removes particles
and moisture from the air stream to prevent damage to the pump and provide proper air
pressure for system operation.
Do not operate the Gas Guzzler system with air pressures exceeding
100 PSI (6 bar).
Higher air pressures will not yield a higher recovery rate, and should
only be used to overcome high discharge head pressures.
The pump’s air supply must never be increased to the point where
the air compressor is running at more than a 50% duty cycle. The
pump should be adjusted so that it runs at its slowest steady
speed. Higher pump speeds will not yield a higher pumping rate,
and will cause premature pump and compressor wear.

14
Section 5: System Maintenance
The Guzzler requires very little maintenance. With proper installation, and by following
periodic maintenance procedures, operation of the system will remain efficient and trouble
free.
Weekly Maintenance
Verify that the Skimmer is set at the correct well depth for the collection of free
product, and that the speed of the pump is correct for the amount of product
available.
Pull the Skimmer from the well and inspect it, making sure the coiled hose is not
tangled and that the buoy moves freely over its travel range. Inspect the buoy
body and clean or replace it as needed, according to the Skimmer user manual.
Monthly Maintenance
Inspect all tubing for cracks, kinks, and damage. Replace any old and brittle
tubing.
Inspect the coiled tubing for physical damage or obstructions. Verify the intake
assembly moves freely over its travel range. (Skimmer)
Inspect the float (buoy) and intake screen. Clean the intake screen and float
according to the Skimmer user manual. (Skimmer)
If using a Total Fluids intake, inspect the intake screen and clean according to
directions found later in this section.
Inspect the Skimmer/Total Fluids Intake for signs of physical damage. Scrapes or
dents in the screen intake may cause the Skimmer/Total Fluids Intake to take on
water. If such damage is found, a new intake assembly may be necessary.
Clear away any debris collected in the well vault (or above ground casement).
Measure the well and record product layer thickness and depth to water from top
of well casing.
Place a Skimmer/Total Fluids Intake positioning mark or zip tie on the discharge
tubing even with the top of well casing.
Re-deploy the Skimmer/Total Fluids Intake, aligning new depth to water mark on
discharge tubing with top of well casing.
Check the Tankfull Shut-off Sensor tube for proper operation. Clean if necessary.
Quarterly Maintenance
Pull Skimmer or Total Fluids Intake from the well.
In cold climates where the temperatures may fall below freezing, the
air supply should be run through an air dryer to prevent the pump
from stalling.
Always ensure all hose and tubing fittings at the Guzzler pump
and between the pump and Skimmer are tight prior to deploying
the unit into the well.

15
Clean the well screen (site specific, primarily to clear bio growth and keep thick
degraded product from impeding conductivity to the well at the product layer.
Frequency to be determined by user).
Place float assembly in water to verify the screen stays out of the water at the top
of the traverse range. If it does not, replace the coiled tubing and retest. If it still
does not, replace the float assembly. (Skimmers)
Cleaning the Skimmer and Intake Screen
For Heavy Oil Skimmers, first use warm, soapy water, followed by a penetrating lubricant
to remove debris or bio growth from the buoy body, then rinse and let dry.
Using warm, soapy water, clean all debris and bio growth from the Skimmer/Total Fluids
Intake shaft and tubing.
Air Regulator Maintenance
1. Turn the AIR ON/OFF switch into the OFF position.
2. Turn off the air supply.
3. Locate the Air Regulator and
turn the adjustment knob on
the Air Regulator fully
counter-clockwise. See
Figure 5-1.
4. Remove the Air Filter bowl
by pushing it upward and
turning counter-clockwise.
5. Clean the bowl with warm
water only. Clean all other
parts with warm water and
soap.
6. Rinse and dry all parts.
7. Blow out internal passages in Air
Regulator with clean, dry compressed air.
8. Blow air through filter element from inside to outside to remove surface
contaminants.
9. Inspect parts. Replace any parts that are damaged.
10. Reassemble the Air Regulator.

Section 6: System Troubleshooting
Problem: The Guzzler operates but recovers no product.
Solutions:
Product has been removed.
Decrease the pumping rate/pressure to conserve air.
Pump is operating too fast, pumping rate exceeds product recharge rate.
Decrease the pumping rate.
Fluid level is below Skimmer assembly.
Adjust the Skimmer as outlined in Section 3: System Installation of this manual.
Viscosity of the product is too thick for the buoy to recover.
Contact Geotech at 1-800-833-7958.
Discharge piping plugged or damaged.
Verify that the discharge piping is clear and undamaged.
Filter material on the Skimmer buoy is plugged.
Clean or replace the filter.
Problem: Pump discharges water only.
Solutions:
Water level has exceeded the allowable travel of the Skimmer buoy.
Pull the Skimmer out of the well and purge water out of the buoy by allowing the
system to pump until all water is removed from the buoy. Refer to the Section 3:
System Installation of this manual and reset the pump and skimmer.
The intake assembly will not slide freely, or the coiled hose is tangled.
Inspect the Skimmer assembly and repair as necessary.
Loose hose or tubing on fittings below intake level.
Check all fitting connections.
The standard 4” Skimmer buoy will travel 24 vertical inches (61 cm) within the well, and
will not pump water unless forcibly submerged. If the water table fluctuation exceeds the
available travel of the buoy, the system may recover water. If the well is slow to recharge
and/or there is only a small volume of product to pump, the pumping rate should be
decreased by turning the speed control valve clockwise to conserve air and minimize
compressor wear.
Problem: The pump discharges air only, no product.
Solutions:
Ensure the pump is primed.
Product has been removed.
Recalculate and reduce the pumping rate.

17
The Product layer is below the bottom of the Skimmer's travel range.
Adjust the position of the Skimmer assembly within the well.
The Skimmer assembly has detached from the pump (due to a cut hose or loose hose
clamp.)
If the Skimmer assembly cannot be removed from the well then a new Skimmer
will be needed.
Problem: The pump cycles but does not discharge product.
Solutions:
The viscosity of the product is too thick for the Skimmer.
Contact Geotech to discuss other Skimmer options for the type of product in the
well.
The intake screen is obstructed or the coiled hose is kinked.
Verify that the intake is clean of debris and bio growth
Check the condition of the coiled hose.
Intake has exceeded maximum depth.
Bring intake up to a depth level pump can handle, maximum of 25’ (7.6m) to fluid.
Use alternate pumping system for deeper wells. Contact Geotech at 1-800-833-
7958.
Problem: Pump does not operate.
Solutions:
Air supply operating pressure is too low.
Verify that the air supply is providing air (45 PSI (3 bar)), use the Air Regulator to
adjust if necessary.
There is a pump malfunction.
Refer to the pump manual or contact Geotech at 1-800-833-7958.
Problem: Pump will not cycle.
Solutions:
Fluid is not high enough to activate the Level Control Valve.
Check fluid level and the position of the sensor tube (see Section 2: System
Installation). Adjust if necessary.
Recovery tank is full.
Turn the air supply OFF. Empty the recovery tank, and turn the air supply ON.
Press RESET on the Guzzler Control Box.
Inspect Tankfull Shut-off Sensor tube and ensure that it is sealed.
Level Control Valve not functioning.
If the Total Fluids Intake is submerged, remove the Level Control Valve and run
the system. If the pump cycles, then first check all of the fittings and connections
between the Level Control Valve and the Total Fluids Intake for possible air
leaks. If no leaks are found and pump is still not cycling there may be a problem
with the Level Control Valve. Contact Geotech at 1-800-833-7958.

18
Air supply operating pressure or flow capacity is too low.
Verify that the air supply is providing air (45 PSI (3 bar)), use the Air Regulator to
adjust if necessary.
There is a pump malfunction.
Contact Geotech at 1-800-833-7958.
Problem: Pump cycles, but flow rate is unsatisfactory.
Solutions:
Check system for kinks in air and discharge tubing.
Check for cuts or air leaks in tubing and tube connections.
Check viscosity of fluid being pumped.
Problem: Pump cycle seems to produce excessive vibration.
Solutions:
Debris clogging pump check valve.
Contact Geotech for service and maintenance.
Problem: Level Control Valve is not working.
Solutions:
Check Level Control Valve plumbing for air leaks. All seals must be tight.
Breather vent may exhaust small amounts of air.
If there are no noticeable leaks, contact Geotech.
If these troubleshooting guidelines have not resolved the problem, then contact Geotech
at 1-800-833-7958.
