3. Safety Instructions
FOR YOUR OWN SAFETY
BEFORE using or servicing your pump or accessories, please make sure to wear the proper clothing, eye protection and follow standard safety
procedures when handling corrosive or personally harmful materials.
GENERAL DANGER
While operating in a hazardous environment or pumping flammable or combustible materials:
ALWAYS use a conductive grounded discharge hose and grounding wire according to these instructions under the section below titled "Static
Protection Kit Assembly." The grounded discharge hose must comply with ISO 80079-36 and CLC/TR 60079-32-1, and must not exceed 10^6 ohms
between each end. Certain fluid applications with the pump may lead to electrostatic discharges. Ensure proper grounding and transferring methods are
followed for the particular fluid.
ALWAYS use a Finish Thompson Haz Loc or ATEX motor rated for the hazardous environment.
NEVER use a plastic pump, plastic accessory, or an open, splash-proof, TEFC, non-Haz Loc, or non-ATEX motor when pumping or mixing flammable or
combustible material.
ALWAYS ensure the pump, hose, and motor are bonded to ground, and the tanks/containers are separately bonded to ground.
ALWAYS inspect the integrity of the ground wire connections prior to each use.
ALWAYS ensure all components above the hose discharge of the pump (motor, bearing, coupling, etc) reside outside of the tank/container.
NEVER leave the pump unattended while in use.
NEVER run the pump dry without fluid.
NEVER run the pump with a closed valve (deadhead) for longer than 1 minute.
ALWAYS use and store the pump and motor in an upright position.
NEVER use in pressurized containers.
ALWAYS use a chemically compatible hose rated for the temperature of the product being pumped.
ALWAYS tighten and torque a stainless steel hose clamp to 25 in-lbs (2.8 N·m)
ALWAYS select the proper o-ring material. Improper material selection could lead to swelling and be a possible source of leaks. This is the
responsibility of the end user.
ALWAYS check the pump for leaks on a regular basis. If leaks are noticed, the pump must be repaired or replaced immediately.
ALWAYS check compatibility and temperature range of pump with liquids used. A Chemical Resistance and Material Selection Guide can be down
loaded from our website at www.finishthompson.com
NEVER use with liquids containing solids that can damage the internals (i.e. metal chips) without optional strainer.
ALWAYS store unit upright, i.e. motor above pump, and away from corrosive liquids and vapors.
ALWAYS check bearings and coupling insert for signs of overheating, abnormal noise or other signs of premature failure on a daily basis. Bearings
and coupling insert should be replaced at the first sign of failure.
DANGER: POWER SUPPLY
Refer to instructions in the appropriate motor Operation & Installation Manual.
4. Noise Level
Refer to specifications in the appropriate motor Operation & Installation Manual.
5. Modifications and Spare Parts
Any changes concerning the service of the pump or accessory as originally purchased can be executed only after written approval from Finish Thompson
Inc. It is recommended to use only genuine Finish Thompson Inc. spare parts and approved accessories. The use of non-original spare parts or non-
approved accessories will void warranty and removes any responsibility on the manufacturer’s behalf for any damage caused to people or things.
6. Cleaning
It is highly recommended to flush pumps and accessories with clean water or some other neutralizing fluid compatible with pump materials when done
pumping or when switching chemicals.

IMPORTANT SAFETY INFORMATION FOR PUMPING FLAMMABLE OR HAZARDOUS SUBSTANCES
Read these instructions before operating the pump and motor equipment. The manufacturer will not be responsible for any damage to property or to persons
caused by improper use of the equipment.
WARNING: It is the responsibility of the user to operate the pump in conformance with OSHA rules for dispensing liquids. Pump containers should be
grounded when using with flammable or combustible liquids to avoid static electricity.
1. Use only an explosion-proof rated electric or non-electric (air) motors on stainless steel pump tubes with a Static Protection Kit when transferring flammable
or combustible liquids.
WARNING: Never use an open, splash-proof, TEFC, battery-operated or non-explosion-proof rated motor or a plastic pump tube when transferring flam-
mable or combustible liquids.
2. When operating a drum pump (especially when pumping flammable, combustible or hazardous liquids) follow all electrical and safety codes.
a) In the United States: the United States Occupational Safety and Health Act (OSHA), most recent National Electrical Code (NEC), National Fire Protec-
tion, Inc. (NFPA) Code 30 (Flammable and Combustible Code), NFPA 77 (Static Electricity), NFPA 251 (Standard Method of fire Test of Building Construc-
tion), NFPA 704 (Identification of the Fire Hazards of Materials), and other NFPA codes, local codes and ordinances.
b) Outside the United States: the ATEX equipment directive 2014/34/EU where applicable, the ATEX workplace 99/92/EC directive where applicable, in
addition the precautions of the U.S. codes listed herein and all other local codes and ordinances.
3. Pumping hazardous, flammable, or combustible liquids should only be done in buildings, rooms, or areas suited for this purpose. (See NFPA 30, NFPA 78, NFPA
80, NFPA 251, NFPA 704, other suitable NFPA codes, OSHA, ATEX workplace 99/92/EC directive insurance companies, and other local codes and ordinances.)
4. When filling cans, drums, etc. with combustible or flammable liquids, both container pumping from and container pumping to, should be bonded and grounded to
dissipate possible accumulations of static electricity, and minimize sparks caused by static electricity (refer to NFPA 77 and CLC/TR 60079-32-1 for specific details).
WARNING: Avoid splashing. Splash filling can create static electricity and is extremely hazardous. Reduce motor speed to prevent splashing.
WARNING: Fluid velocity must be 3 feet/.9 meter/second maximum (7 gpm/26.5 lpm in 1” hose and 4 gpm/15 lpm in ¾” hose) to reduce risk of static
electricity. Reduce motor speed to reduce the fluid velocity.
5. Before using, confirm that the pump and any accessories (hose, nozzle, flow meter, etc.) materials of construction are suitable for the material to be
pumped and that the maximum temperature is not exceeded.

OPERATION
1. Make sure the motor (electric or air) is properly installed on the pump tube and is in the o position. See
motor instruction manual for installation instructions.
2. Insert the pump tube into the fluid to be dispensed and the hose into the container to be filled prior to starting the pump. Bung adapters are available to provide
a tighter fit between the pump tube and bung opening of a standard drum. Check drum pump accessories at www.finishthompson.com or contact your local Finish
Thompson distributor for bung adapter info.
3. Make sure the pump’s discharge hose is properly secured before operating the motor, torque Finish Thompson hose clamps to 25 in-lbs(2.8 N·m).
4. Begin pumping by turning the motor on and verifying that there are no leaks. If leaks are noticed immediately turn the motor o and check all discharge hose
connections.
NEVER allow the pump to run dry.
NEVER pump liquids containing solids that can damage internal pump parts (i.e. metal chips). Pumping solids
can lead to increased wear.
Static Protection Kit Assembly
Hose attachment to pump:
1. Place the stainless steel hose clamp onto the short section of the grounded hose.
2. Slide the short section of the grounded hose assembly over the pump tubes discharge spout. Tighten and torque the SS clamp to 25 in-lbs (2.8 N-m).
3. Attach the ground wire assembly to the pump tube using the #8 ring terminal and supplied 8-32 x 1/4" brass screw and brass lock washer.
4. Attach the ground wire assembly to the motor (see instructions below).
5. Check the electrical continuity between the clamp on the end of the ground wire assembly and the end of the grounded hose. The electrical resistance must be one (1)
Ohm or less. If it is greater than one (1) Ohm, re-check all connections.
Hose & Cord Storage
SF model pumps have a built-in hose & cord clip. You can use these clips to store your hose and keep the plug o the floor, free of damage and corrosion. When
selecting a discharge hose, you should use a 1" ID reinforced chemically compatible hose secured with a stainless steel hose clamp. See figures A and B below.
Choice of two types of Impellers
The SFS-Series pump models can be ordered with either a "High Flow" or "High Head" impeller. The high flow impeller utilizes an axial design impeller and built in
strainer/diuser cover for quickly dispensing fluids from drums & totes. The high head impeller utilizes a centrifugal design impeller to produce high head for dispensing
through long hose runs or to overcome high system pressures. Either impeller can be used with the same pump but it is important to use the correct diuser cover to
attain the proper performance. See figures below.

DISASSEMBLY & REASSEMBLY INSTRUCTIONS
Disassembly
Figure 1 A & B
1. Cover, Impeller, & Diuser Removal - Unthread the diuser
cover (item 22 or 23). Turn it clockwise (left-hand thread). See
Figure 1 A & B. Unthread the impeller (item 20 or 21) turning it
counter clockwise (right hand thread) using your hand while
holding the coupling insert and coupling (items 1 & 2) with the
other hand. See Figure 2 A & B. Note: If the shaft unthreads
from the coupling, use a pliers to hold the bottom of the shaft
just above the impeller. See figures 3 A & B. For longer 40” to
72” pump lengths, two people may be required to hold the shaft
and unthread the impeller.
2. Shaft Removal - To remove the shaft (item 4), tap the bottom
of the shaft on a piece of wood or plastic and push the shaft up
and out of the head (item 6). See Figure 4 A & B. Grab the half
coupling or bearing and pull the shaft assembly straight out of
the head. Note: Take care to not bend the shaft.
Important - The shaft should only be removed if the bearing
is frozen and needs to be replaced. Hold the pump shaft (item
4) with a pliers or vise grip. Turn the half coupling (item 2)
counter clockwise (right hand thread) to remove it from the
shaft. The bearing (item 3) will slide o the shaft. See Figure 5
A, B, and C. If the bearing is frozen or corroded to the shaft use
a penetrating fluid and socket to help tap it o. Install a new
bearing (item 3), reuse and hand tighten the half coupling (item
2). These items will only fit properly on one end of the shaft.

2. Inner Tube Installation -
Reinstall the inner tube (item 14). The double o-ring side seats up
into the head with a slight twisting motion. Make sure the inner
tube is seated properly. It is recommended to use a compatible
lubricant or water on the o-rings. See figures 11 A & B.
3. Intake Tube Installation -
Install the intake tube (item 16). Slide the intake tube with
external threads over the inner tube up into the head (item 6).
While pushing the intake tube's threads beyond the o-ring, turn
the intake tube counter clockwise (left hand thread) to tighten it
into the head. Ensure the threads do not start to cross-thread.
Hand tighten. The bottom of the inner tube will be recessed
slightly with the bottom of the outer tube when properly seated.
See figures 12 A, B & C.
4. Reinstall the half coupling, bearing and shaft (items 2, 3, & 4
indicated on the Exploded View Drawing) as an assembly into the
head. If the bearing needs to be replaced see section 2 of the
disassembly instructions on the prior page. See figures 13 A & B.

6. Diuser Installation - Install the diuser (item 8) onto the bottom of the outer tube. This is a tight fit so it is recommended to use a compatible
lubricant or water. Insert the shaft through the small support opening on the diuser. The small support opening will insert up inside the inner tube
(item 12). With a slight push and turn, thread the diuser into the outer tube (item 6) turning counter clockwise (left hand thread). Thread the diuser
(item 6) completely onto the bottom of the outer tube (item 5). Hand tighten. See figures 15 A, B, & C.
7. Thread the impeller (items 20 or 21) onto the shaft by hand. While holding the half coupling with the other hand, turn the impeller clockwise (right
hand thread). Install the diuser cover (item 22 or 23) onto the diuser turning counter clockwise (left hand thread). Hand Tighten. See Figures 16 A,
B, C, D, E, F, & G.
5. Shaft Installation - Slide the shaft down through the seal until the
bearing engages the bearing bore in the head. Set the half coupling
on the floor and push the pump down using the intake tube (item 16)
for leveridge. Make sure the bearing (item 3) is flush with the top of
the head (item 6). While the pump is in thie upright position slide the
shaft sleeve (item 15) between the shaft (item 4) and inner tube (item
14). The shaft sleeve is self positioning so just push it in all the way
completely into the inner tube. Sleeve is flared on the bottom to help
hold it in position. See figures 14 A, B, C, D.
