PRODUCT OVERVIEW
PUMP END
Our systems feature patented Tri-Lobe positive displacement
impeller technology that provides dry-run, dry suction lift, and
flow performance like no other positive displacement pump in
the industry.
APPLICATION AND INTENDED USE
The Dixon Pumps single-housing filtration dolly (FS1) is a compact mobile fuel filtration solution for cleaning fuel. It can be easily moved
where tank locations have limited access, and is easily transported from place to place. Unlike Dixon’s FS2 that has 2 filter housings, the
FS1 only has 1 bag housing. It is designed to be more compact and lighter for moving into hard to access areas and for smaller filtration
applications.
POWER UNIT
This unit is powered by high-quality blue chip AC EP and Non-
EP Marathon motors. The power specifications are as follows:
GEAR REDUCER
This unit utilizes a gear reducer between the power unit and the pump
end. The gear reducer changes the rotation of the pump speed through
reduction gearing in the gear reducer housing. This unit is available in
the following gear reducer options:
PERFORMANCE – FLOW AND PRESSURE
Flow and pressure performance depend on the speed of the pump
shaft and the available horsepower provided by the power unit.
Higher pump shaft speed results in higher flows, and higher HP
results in higher pressures. The flow and pressure performance
specifications for this unit are as follows:

PERFORMANCE – FLUIDS
The Dixon Pumps FS1 Dolly EP (Explosion-Proof) model is designed for use in explosive environments (U.L. /C.S.A., CLASS 1.
DIVISION 1. GROUP D, CLASS 2, GROUP F AND G). All models are intended for handling petroleum fluids (including diesel, bio-
diesel and most lubricants).
PERFORMANCE – SUCTION LIFT AND CAVITATION
Suction lift performance depends on many factors. The vapor pressure of the fluid is a key factor in whether or not a pump will lift
fluid from below the intake of the pump. High vapor pressure fluids are more difficult to lift from below the pump intake. Additionally,
since atmospheric pressure is the key driver of suction lift performance, elevation of the pumping location must be considered. It will
be easier to lift fluid through the pump at sea level than at higher elevations.
Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the
suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). When cavitation takes place, air bubbles are
created at low pressure. As the liquid passes from the suction side of the impeller to the delivery side, the bubbles implode.
This creates a shockwave that hits the impeller and creates pump vibration and mechanical damage, possibly leading to
complete failure of the pump at some stage.
In order to prevent cavitation, the user should calculate the NPSHa for the application to ensure that NPSHa > NPSHr

Use of high quality camlock fittings with locking levers is
recommended to avoid hazardous spills.
REVERSE ROTATION
The FS1 SERIES systems are not designed to be operated in
reverse rotation.
PUMP BYPASS FEATURE
The pump end on this unit is a Dixon Pumps positive displacement
pump. Positive displacement pumps require a bypass mechanism to
relieve the pressure in the system when there is a blockage, valve,
or nozzle on the discharge side of the pump.
FILTER HOUSINGS – FILTER ELEMENT ACCESS
The filter housing is equipped with a removable lid that is secured
with four eye bolts. After relieving pressure in the system, the
housing lid can be removed by loosening all four bolts and
completely removing three of them. One of the eye bolts can be left
in place to hold the lid as it is rotated out of the way.

BAG FILTER HOUSING PREPARATION
Determine which bag filters will be used. Prior to installing bag filter,
make certain the bag filter basket is installed. Make sure the o-ring
is installed on the basket prior to setting it in the housing. Bag filters
should be fitted into housing so the bottom of the bag is pressed
down all the way into the filter basket and the retainer ring seats
completely against the top of the basket so that no particulates blow
by the filter.
An alternative to the standard bag filter configuration is the drop-in
cartridge filter element. This is a cartridge filter that is configured to
fit into our standard bag filter housing, allowing finer
filtration/polishing of the fluid through the inlet side of the pump.
If a stainless steel mesh basket is to be used in place of a bag filter,
remove the bag filter basket (see Page 6) and replace it with the
mesh basket. Double-check to make sure the o-ring is installed on
this basket prior to setting it in the housing. Keep in mind that a
maximum of 74 microns is allowed. Also remember that the lower
the micron rating of the filter element, the better the fuel quality and
the fewer cartridge filters that will be required to attain the target
cleanliness.
Once bag filter, drop-in cartridge, or stainless steel mesh basket is
installed, close the housing. Make sure the housing o-ring is in
place and contains no pinched or broken areas. If pinched or
broken, replace before using the FS1. To close, line up lid and
housing; insert eye bolts; hand tighten bolts only.
Be aware that there are limitations to the dry lift and suction
capability of the pump. Adding too much hose, or trying to lift from
too deep can cavitate the pump or may just result in a lack of fluid at
the inlet.

DRAINING THE FILTER HOUSINGS:
Each housing comes equipped with a drain valve. The valve is open
at the 90⁰angle position. It may be necessary to connect the
provided clear tubing to the valve in order to drain housing into a
bucket.
THE CONTROL PANEL:
The control panel comes equipped with a vacuum gauge.
The Vacuum Gauge measures the
vacuum pressure in the bag filter
housing. As the filter collects
particulates, the gauge moves
indicating a dirty filter. Once it
reaches the red zone, it is time to
remove and replace it with a new
bag.
OPERATION – FILTRATION PROCESS
THE FILTRATION PROCESS
The diagram below shows a typical set-up for filtration. When
filtering fuel, it is important to remove any heavy contaminants and
water found on the bottom of the tank before filtration begins. If free
water is not removed from the bottom of the tank, it will become
emulsified during the filtration process, making removal more
difficult.
Once contaminants are removed and properly disposed, filtration
can begin. There are several steps in the filtration process as well
as important factors to understand for quality results.
There are basic steps to every filtration job. These are meant to be
set-up guidelines for a typical filtration job. Every fuel system is
different and may require a set-up variation. The below steps are
meant to serve as a simple guideline:
1. Set-up site for safety. Dixon Pumps recommend each
technician take the OSHA Hazwoper training course prior to
using a Dixon product for safe field operation.
2. Access tank area once safety barriers are in place and notify
the site operator.
FAILURE TO REMOVE AND DISPOSE OF FREE WATER
BEFORE STARTING THE FILTRATION PROCESS COULD
RESULT IN EMULSIFICATION OF THE WATER INTO THE
FUEL! EMULSIFIED WATER IS MORE DIFFICULT TO
REMOVE THAN FREE WATER.

3. Set out two fire extinguishers – one in containment pool once
setup and one off to the side but still within the worksite area
4. Use of a Dixon Spill Containment Pool and Emergency Spill Kit
is advised. Set up the portable containment pool and position
the spill kit within easy reach but out of the way so as not to be
a trip hazard. See pool and spill kit below:
CONTAINMENT POOL
SPILL KIT
5. Setup FS1 as close to tank access as possible. Place the FS1
in the center of the containment pool.
6. Take a bottom sample of fuel at each
available access point using a Dixon
Pumps Fuel Sampler. It is important to
take samples from several locations,
as contaminants will migrate to the
lowest part of the tank. Save the
samples for photographic record once
job is complete.
7. Place suction pipe at the lowest access point in the tank. This
is determined by identifying the access point in the tank that has
the highest level of contamination on the bottom.
8. Connect suction hose to suction pipe and the intake coupling on
the FS1.
9. Place return pipe into your supplied PCW (petroleum contact
water) or contaminant storage container and connect the
discharge hose to both the FS1 and the return pipe. The
amount of contamination measured while sampling will
determine the amount of storage required. Make sure you have
enough prior to beginning.
10. When operating in a hazardous environment using an
EXPLOSION-PROOF model, attach grounding wires from the
fuel tank or drop tube to the FS1. Attach a second grounding
wire from the FS1 to a suitable ground such as a lightning
ground near a building. Use a grounding rod if there is not a
suitable ground nearby. Hammer into ground and attach
second grounding cable to rod prior to use. In dry conditions,
wet the ground touching the rod for better conductivity.

11. Pump out and properly dispose of water and biomass
contamination at the bottom of the tank. Once done, thoroughly
drain discharge hose and return pipe in preparation for
relocating it to tank.
12. Place return pipe in the opposite end of the tank, farthest away
from the suction pipe. The farther the spread, the better.
13. Connect the discharge hose to the return pipe.
14. Double-check system connections and safety barricades.
Always remain aware of your surroundings. Safety First!
15. Begin filtering fuel. Watch the gauge on the system housing
and change filters as needed. Water and contaminants can
collect in the bottom of the housing, so periodically drain a small
amount of fluid from housing to make sure water and
contaminants are adequately removed.
16. Take a bottom sample of the fuel several times from all access
points during the filtration process to determine progress and
final fuel quality. Keep an eye on the inlet and outlet sight
glasses to verify fuel quality as it passes through the system.
17. Once fuel appears clear from all access points, take a final
bottom sample.
18. Record photo results against a Fuel Clarity Bar Chart like the
one shown below.
19. Close up tank access points.
20. Clean the workspace.
21. Pack up all equipment.
22. Report results to site operator and provide detailed work order.

FILTER SELECTION AND APPLICATION
Choose filters according to the desired quality of the fuel. Always use a bag filter or Dixon’s optional stainless steel 74 micron filter basket to
eliminate particulates that could damage the pump. Concentrations of particles can damage the pump, so the Bag Filter Housing must have
at least a 74 micron filter or basket installed to remove large particulates from the fluid stream.
Achieve finer filtration by using progressively smaller filter mesh sizes according to the desired quality of the fuel or ISO requirement. Using
a smaller mesh bag filter in the Bag Filter Housing will lengthen the life of the cartridge or coalescer filters installed in the Coalescer/Water
Separator Housing. Dixon’s FS1 can be used for fuel filtration, including water removal (using an absorption filter). Choose from the filtration
options below for the required fuel standard.
BAG FILTERS AND STRAINERS
Pro Series Bag Filters
Dixon Pro Series bags are made from the leading nonwoven media
produced from the highest quality liquid filtration felts. Our polyester
filtration media surface is treated to prevent downstream fiber migration.
They are silicone free, perfect for hydrocarbon and paint applications.
The Pro Series bag comes standard with a polyseal retainer that is
flexible to fit most filter housings and chemically resistant. The retainer
has an integral handle for ease of installation and removal. Our bags
are all fully welded using the most advanced thermal bonding
technology. The process provides strength, durability and worry-free
filtration. The bonded seams eliminate the use of threads and the
opportunity for bypass caused by needle holes created with the
traditional sewn seams. This results in a stronger more efficient bag
filter.

BAG FILTERS AND STRAINERS (Cont.)
Pro+ Series Bag Filter
The Dixon Pro+ Series is designed for longer service life. The high performance felt consists of a unique
blend of fine fibers combined to create a thicker, loftier felt media with greater dirt loading capacity. The
result – a bag filter capable of holding 2 to 4 times the amount of contaminants than the standard felt bag
filter. Longer service life translates into lower operating costs and downtime. Like the Pro Series, the
surface is treated to prevent downstream fiber migration and is silicon free. It comes with an engineered
retainer and is thermally bonded. See the thickness difference between the standard Pro and the Pro+ felt
in the picture to the right. The depth of the media allows for greater holding capacity.
Applications
•Petroleum
•Lubricants
•Coolants
•Automotive
Stainless Steel Mesh Basket Strainers
The Dixon Mesh Baskets are made of 304 stainless steel and can be used with or
without a bag filter. The 200 mesh basket strainer is equivalent to a 74µm bag and
can be used to substitute for a bag when heavy particulates are expected, as a cost-
effective measure.
Strainer baskets come in P1 and P2 sizes. They are designed with a handle for easy
installation and removal. An O-ring is provided to ensure a proper seal, but is not
meant to take the place of an Omega Spring.

CARTRIDGE FILTERS
Pleated Paper Cartridge Filters
Dixon pleated filters are high efficiency, nominally rated cartridges designed to effectively remove
particulate contamination from fuels, oils, coolants, paints and solvents. The filters are made for high flow
rates, low initial pressure, high fatigue strength and long-life cycles. They come in a variety of sizes and
micron ratings. These filters are a low cost, high quality product.
Absorption Cartridge Filters
While coalescer filters are highly cost effective in separating and removing emulsified water, additives and surfactants in fuels and lubricants
can impair their separation capability. Water absorbing cartridges are a combination of pleated paper filtration and water absorbing
polymers. Dixon absorption cartridges are made for maximum dirt-holding capacity and water hold capacity. The perforated metal
reinforcement tube provides structural rigidity accounting for a 75 PSID collapse pressure rating. This filter is not compatible with ethanol
enriched fuels or jet fuel containing deicing agent.

MAINTENANCE INSTRUCTIONS

Document No.: 48-00003 Revision A Page: 19
MAINTENANCE
1) Pump - The Dixon pump requires minimal maintenance, but the
following maintenance procedures are required for maximum
performance:
a) Every 2,000 hours of operation, the gear chamber should be
drained and replaced with 12-14 ounces of synthetic
lubricant. The recommended lubricant type is Mobil SHC-
626
b) Periodically, all nuts and bolts should be checked and
tightened securely to ensure maximum performance of the
pump unit.
2) Gear Reducer – The pump unit on the FS1 comes with a “Grove
TXQ” gear reducers that require very minimal maintenance.
a) The mounting bolts should be checked for tightness every
50 hours of operation.
b) The standard compounded lubricants (non-synthetic) should
be changed every 6 months or 2,500 operating hours.
c) All standard reducer from Grove Gear are filled with Mobil
Glygoyle 460 Polyglycol (PAG) lubricant designed to operate
with -10⁰to 120⁰F ambient temperature range. The gear
reducer should not become hot enough to cause breakdown
in the synthetic lubricant. Should there be any questions or
concerns, contact Dixon Pumps for further details and
technical support.
3) Dolly
a) Dolly wheels – The bearings on the dolly wheels need to be
greased periodically to lubricate the ball-bearings. You will
find a grease-zerk in the inside of each wheel for adding
lubricant to the ball-bearings. Recommended tire pressure
is 30 P.S.I.
b) Containment tank - When the containment tank on the dolly
is full, it should be drained. Move the pump unit over a
product drain area and tilt pump unit back until the pump unit
is vertical. There is one petcock on the bottom of the
containment tank. Turn the petcock on the bottom of the
containment tank clockwise to open, and drain the excess
product. When the containment tank is completely drained,
turn the petcock counter clockwise until it is securely
tightened.
4) Couplings and Hoses – Couplings and hoses should be checked
periodically for leakage and wear. As excess wear appears, the
components should be replaced to prevent any accidental
spillage.
WARNING
Hazardous or toxic fluids can
cause serious injury.
CAUTION! WHEN PUMPING ANY TOXIC, CORROSIVE OR
PRODUCTS THAT WILL LEAVE A FILM OR DEPOSIT OF
ANY KIND, THE PUMP SHOULD BE FLUSHED
IMMEDIATELY AFTER USE.

TROUBLESHOOTING
SYMPTOM PROBABLE CAUSE REMEDY
The suction lift capacity of the pump may not be suffiecient. A higher pump shaft
speed or a larger diameter lift piping may be required.
Reduce vertical lift distance between the fluid level and the inlet of the pump.
Install a foot valve in the lift piping to maintain a column of fluid in the lift piping/string.
This will eliminate the need for dry-lift performance from the pump.
Pump has not yet filled with fluid.
Fill inlet housing with fluid to be pumped. This can be achieved by accessing the plug
nearest the bypass cap in the bypass housing.
Pump impellers are not sealing properly
Fill inlet housing with fluid to be pumped. If there is no improvement, check impeller
vanes to ensure there is no damage or wear and tear that may have caused a loss of
vacuum.
Line plugged or filter clogged
Flush the blockage out of the line and clean any filter or strainer on the inlket side of the
pump.
Suction line flush on bottom of drum or tank Suction line needs minimum 1 inch clearance on all sides
Loose, unsealed fittings Check all fittings for proper sealing
Loose bands or pin holes in the hoses Check banding, hose, and any fittings in the inlet piping for proper sealing
Circuit breaker too small or overloaded
Check the required amperage and voltage for the motor. The power supply components
(in the starter box or 3-phase panel) should be sized properly for operating the motor at
the required power specifications.
Too much back pressure / system pressure on the
motor.
There is too much flow resistance in the flow system for the motor to overcome. This
bypass should be sized to avoid overloading the motor.
Outlet plumbing too small.
Piping diameter is a critical factor in the backpressure generated on the pump. If the
piping is too small, the backpressure can be too high for the pump and may overload the
motor if the bypass pressure is close to the overload point of the motor. Call Dixon
Pumps for guidance.
The fluid being pumped is too viscous.
Viscosity is another critical factor affecting the backpressure on the pump, and may rise
to a point high enough to overload the motor if the bypass does not open in time.
Viscosity of the fluid must be considered, especially if the ambient temperature is
expected to be cold.
The by-pass is opening.
The by-pass valve will open at the by-pass pressure setting, determined by the spring
that is installed in the bypass housing. Make sure the bypass pressure is high enough
(and the HP of the motor is sufficient) to support the system pressure required for the
application.
The inlet and/or outlet hose diameter has been
reduced.
The flow rate will decrease if the inlet or outlet hose diameter has been reduced.
Confirm rotation of the pump shaft by visual inspection through the coupling flange
access port which is sealed with a black plastic plug. The shaft should be rotating
counterclockwise when looking from the gear reducer to the pump end.
The motor wiring at the junction box, VFD, or panel may have been wired backwards.
Check the wiring diagram and make sure the wiring to the motor is correct for forward
rotation.
Remove the bypass housing (six hex bolts) and check for any lodged objects in the
spring or valve seat.
