Installation & 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.
6. Install into the container.
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).
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.
