BTS Installation and Maintenance Instructions

Installation
Remove the drum pump and motor from its packaging and inspect for shipping dam age. Remove
the quality tag from the top of the pump and spin the pump coupling to verify there is no binding.
Remove the black rubber coupling insert (item 1) from the attached plastic bag, and install it onto
the pump coupling. Adjust the coupling so that the empty slots in the insert are at 3 and 9 o’clock
with the pum p discharge at 12 o’clock. Rem ove the 2 m ounting bolts from the m otor/motor
mount and adjust the m otor coupling so that the coupling prongs are at 3 and 9 o’clock with the
handle (on electric m otors), or the air supply line ( on air m otors) at 6 o’clock. Install the m otor
onto the drum pump until it seats all the way down with the couplings connecting and install the 2
mounting bolts with nuts. Attach discharge hose and install into the container.
Maintenance Disassembly
1. Loosen the setscrew and remove the coupling half (item 2) from the end of the pump shaft.
2. Carefully holding the intake tube (so as not to crush the tube ), use a 3/8” punch and
hammer to drive the bottom of the pum p shaft (item 10) up through the intake tube (item
7) until the bearing assembly (item 3) is completely exposed.
3. Use a 1/8” punch to rem ove the roll pin that holds the bearing assem bly (item 3) onto the
pump shaft, and remove the bearing assembly.
4. Remove the setscrew (item 13) from the botto m of the intake tube and rem ove the bottom
bearing (item 12).
5. Now drive the shaft assem bly back down th rough the intake tube and rem ove it from the
bottom. Remove and discard the seal assembly (item 4) from the top of the pump head.
Inspection
1. Inspect the bottom bearing for dam age or we ar (if ID is .400 or larger) and replace as
needed.
2. Visually inspect the compressors (item 8) for damage or wear and replace as needed.
3. Visually inspect the pump shaft for wear in the bottom bearing ar ea and in the seal
assembly area. Replace as needed.
4. Inspect the bearing assembly for rust, corrosion, or tightness and replace as needed.
Reassembly REL 4-8-02
Reassembly
1. Insert the shaft assembly up through the bottom of the intake tube (item 7) until the end of
the shaft sticks out above the top of the pump head.
2. Warm up the seal assembly (item 4) prior to installation by using a heat lam p 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 coupling 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 w ith the two “slots” facing up to ward the bearing assembly.
The raised lip in the center of the seal (that faces the bottom of the pum p) m ust go on
straight and not buckle on one side.
4. After the seal is on the shaft correctly, insta ll 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. Carefully press on the shaft end to slide th e bearing assem bly into the pum p head. Use a
block of wood and a mallet if needed to drive the assembly into the pump head. Be careful


not to mushroom the shaft head or the coupling half will not go on.
6. Install the coupling half (item 2) on the end of the shaft and tighten the setscrew into the
dimple on the shaft. Make sure the setscrew bottoms out in the dimple.
7. Reinstall the bottom bearing (item 12), and tighten the setscrew that holds it in place.
8. Spin the pump coupling to insure there is no binding.
