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 flammable
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
Protection, Inc. (NFPA) Code 30 (Flammable and Combustible Code), NFPA 77 (Static Electricity), NFPA 251 (Standard Method of fire Test of Building
Construction), 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 ordi-
nances.)
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 electric-
ity. 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.
INFORMATIONS IMPORTANTES SUR LA SÉCURITÉ DURANT LE POMPAGE DE SUBSTANCES INFLAMMABLES OU DANGEREUSES
Veuillez lire attentivement ces instructions avant d’utiliser la pompe et l’équipement du moteur. Le fabricant ne sera pas tenu responsable des dommages matéri-
els ou corporels causés par une utilisation inappropriée de l’équipement.
AVERTISSEMENT: Il est de la responsabilité de l’utilisateur de faire fonctionner la pompe conformément aux règles OSHA (Santé et Sécurité au Travail)
relatives à la distribution de liquides. Les conteneurs de pompes doivent être électriquement mis à la terre lors de l’utilisation de liquides inflammables ou
combustibles afin d’éviter toute électricité statique.
1. Lors du transfert de liquides inflammables ou combustibles, utilisez uniquement des moteurs électriques ou non électriques (pneumatiques) antidéflagrants
sur des tubes de pompe en acier inoxydable dotés d’un dispositif de protection antistatique.
AVERTISSEMENT: N’utilisez jamais de moteur ouvert, à l’épreuve des éclaboussures, TEFC, alimenté par piles ou non antidéflagrant, ni un tube de pompe en
plastique lors du transfert de liquides inflammables ou combustibles.
2. Lors de l’utilisation d’une pompe à tambour (en particulier lors du pompage de liquides inflammables, combustibles ou dangereux), respectez tous les codes
électriques et les codes de sécurité.
a) Aux États-Unis : Loi américaine sur la sécurité et la santé au travail (OSHA); le code national de l’électricité (NEC) le plus récent; le code 30 de la
NFPA (code d’inflammabilité et de produits combustibles); le code NFPA 77 (électricité statique); le code NFPA 251 (Méthode standard de test

Installation, Operation, & Maintenance Instructions
Installation
1. Remove the drum pump and motor from the packaging and inspect for shipping damage. Turn the pump coupling the mating
motor coupling to verify there is no binding.
2. Adjust the drum pump coupling so that the empty slots in the insert are at 3 and 9 o’clock with the drum pump discharge at 12
o’clock.
4. Install the motor according to instructions in the appropriate motor manual.
5. Attach discharge hose and secure with hose clamp. Torque Finish Thompson hose clamps to 25 in-lbs (2.8 N·m).
6. Install into the container.
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.
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.
Cleaning (STTS only)
The STTS model is designed to come apart easily to aid in cleaning.
1. Remove the union nut (item 5) and, grabbing the bearing housing, pull the shaft assembly from the intake tube (item 10). The
shaft assembly and intake tube internals can now be cleaned and flushed.
2. Always inspect the union nut gasket (item 7) for cuts or damage.
3. Reverse the process to reassemble this model.
Maintenance
Disassembly
1. Loosen the setscrew and remove the half coupling (item 2) from the end of the pump shaft.
2. Carefully hold the intake tube (the bearing housing on the STTS model after the cleaning disassembly step) so as not to crush
the tube, use a 3/8” punch and hammer to drive the bottom of the shaft toward the top. This will drive the bearing assembly up
out of the TTS/TTC head or STTS bearing housing.
3. When the bearing is completely out, use a pair of needle nose pliers and carefully straighten the four slightly bent “feet” at the
bottom of the intake tube on the TTS model. This will allow you to use the pliers to remove the bottom bearing (item 13).

10
4. Then use a 1/8” punch to drive out the roll pin that holds the bearing onto the top of the pump shaft. Remove the bearing from
the pump shaft, and remove shaft assemble down through the bottom of the intake tube. On STTS models, pull the shaft
assembly down out of the bearing housing.
5. Remove the seal assembly from the pump head on the TTS/TTC or the bearing housing on the STTS and discard it.
Inspection
1. Inspect the shaft locating hole in the center of the bottom bearing (item 13 on the TTS/TTC and 16 on the STTS. If the inside diam-
eter is .400 or larger than replace it.
2. Visually check the all the compressors (item 9 on TTS/TTC and item 12 on STTS) for damage. If they need replaced, you must
remove the pin first.
3. Visually inspect the center bearings (item 12 on TTS/TTC or item 15 on STTS), the spacers (item 10 on TTS/TTC or item 13 on
STTS), and the impellers (item 8 on TTS/TTC or item 11 on STTS). Replace as needed.
4. Never reuse the seal assembly (item 4). Always install a new seal during reassembly.
5. Inspect the bearing assembly (item 3), and replace if needed.
6. Inspect the pump shaft for wear in the seal area, the center bearing area, and the bottom bearing area. Replace if needed.
Reassembly
1. With the center bearings, compressors, spacers, and impellers in place on the shaft, insert the shaft up through the bottom of
the TTS/TTC intake tube (up through the bottom of the bearing housing on the STTS).
2. Warm up the seal assembly (item 4) prior to installation by using a heat lamp or soaking them in hot water. This will aid in the
ease of proper seal installation. Make sure there are no metal burrs on the pump shaft in the bearing hole location or the cou-
pling half setscrew location that could “cut” the seal during installation.
3. Lubricate the end of the shaft with Vaseline to aid in the seal installation. Carefully install the seal down over the shaft with the
two “slots” facing up toward the bearing assembly. The raised lip in the center of the seal (that faces the bottom of the pump)
must go on straight and not buckle on one side.
4. After the seal is on the shaft correctly, install the bearing assembly (item 3) onto the shaft. Use the bearing assembly to push the
seal further down the shaft until the hole in the center of the bearing assembly matches up to the hole in the shaft. Install the roll
pin through the bearing assembly and shaft.
5. Turn pump intake tube (bearing housing on the STTS) upside down and press on the shaft end to slide the bearing assembly into
the pump head (bearing housing on the STTS). Use a block of wood and a mallet if needed to drive the assembly into the pump
head.
6. Install the coupling (item 2) on the end of the shaft and tighten the set screw into the dimple on the shaft.
7. On STTS models insert the shaft assembly into the intake tube from the top, making sure to install the union nut gasket (item 7)
and tighten the union nut (item 5).
8. Reinstall the bottom bearing (item 13 on TTS/TTC and item 16 on STTS), and gently bend the four “feet” in slightly to keep the
bottom bearing in place on the TTS and STTS models.
9. Turn the pump coupling to insure there is no binding.
