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:

** Particle size tolerence depends on duration and volume of exposure. Larger particles can be
tolerated during intermittent and incidental exposure. Long-term exposure when removing dirty
oil and debris, or during tank cleaning can damage the pump, requiring filtration or screeing to
smaller particle size.

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

PUMP SPEED AND HORSEPOWER
This unit is equipped with a gear reducer that turns the pump shaft
at a reduced speed relative to the motor shaft. It is available in
multiple speed (flow) and HP (pressure) options. Please see the
“Product Overview” section for details on the gear reducer and HP
specifications for your model to determine flow and pressure
performance. Be sure to take this into consideration when verifying
the applicability of this unit for pumping/filtration applications.
HOSE CONNECTIONS
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.
WHEN PUMPING FLAMMABLE LIQUIDS WITH
EXPLOSION-PROOF MODELS,
ALL HOSE COUPLINGS MUST BE EXPLOSION
PROOF RATED. ALL HOSE MUST HAVE A
STATIC WIRE, AND MUST ALSO BE UL LISTED
FOR CLASS 1, DIV 1, GROUP D, CLASS 2,
GROUP F AND G (CANADA: MUST BE CSA LISTED)
DANGER
Flammable fluids can explode,
causing serious injury, death, or
property damage.
DANGER
Flammable fluids can explode,
causing serious injury, death, or
property damage.
WHEN PUMPING FLAMMABLE FLUIDS SUCH AS
GASOLINE (NFPA CLASS I LIQUIDS) WITH EXPLOSION-
PROOF MODELS, DO NOT ALLOW THE PUMP TO STAY
IN BYPASS FOR LONGER THAN ONE (1) MINUTE.
WHEN CHANGING FILTERS, TIGHTEN FILTER HOUSING
LIDS BY HAND. DO NOT USE TOOLS ON FILTER
HOUSING EYE BOLTS. OVERTIGHTENING CAN RESULT
IN DEFORMATION OF THE CANISTER LID AND FAILURE
OF LIQUID-TIGHT SEAL!
CAUTION
WARNING
Hazardous pressure can cause
personal injury or property damage
WHEN REPLACING FILTER ELEMENTS, MAKE SURE THE
PUMP IS OFF AND THE PRESSURE IS RELIEVED BEFORE
OPENING THE FILTER HOUSING LID.
WHEN USING A SHUT-OFF NOZZLE, THE PUMP WILL
OPERATE IN THE BY-PASS MODE (FLUID WILL
CIRCULATE AROUND INSIDE THE PUMP THROUGH THE
BYPASS FLOWPATH) IF THE NOZZLE IS IN THE “OFF”
(CLOSED) POSITION. THE PUMP SHOULD NOT BE
OPERATED FOR MORE THAN FIVE (5) MINUTES IN FULL
BY-PASS MODE FOR NFPA CLASS II AND CLASS III
LIQUIDS.
