Installation & Maintenance Instructions
Installation
1. Remove the drum pump and motor from its packaging and inspect for shipping damage.
2. Turn the pump coupling to verify there is no binding.
3. Adjust the coupling so that the empty slots in the insert are at 3 and 9 o’clock with the pump discharge at 12
o’clock.
5. Install the motor according to instructions in the appropriate motor manual.
6. Attach discharge hose and install pump into the container.
Maintenance
Disassembly
1. Loosen the setscrew and remove the half coupling (item 2) from the end of the pump shaft.
2. Gently holding the intake tube so as not to crush the tube, use a 3/8” punch and hammer to drive the bottom
of the shaft (item 11) toward the top. This will drive the bearing assembly (item 3) out of the top of the
pump. Stop when the bearing assembly is exposed.
3. Use a 1/8” punch and drive out the roll pin that is located in the center of the bearing assembly (item 3), and
slide the bearing assembly off of the shaft.
4. Remove the pump shaft assembly by pushing it down through the intake tube (item 7) and out the bottom.
5. Remove the seal assembly (item 4) and discard. Never re-use a seal assembly.
Inspection
1. Visually inspect the impeller assembly (item 8), the center bearings (item 10), and the compressor (item 12)
for damage and replace as needed.
2. Inspect the bearing assembly for rust, corrosion, or tightness and replace as needed.
3. Inspect the pump shaft in the seal area and the center bearing areas for excessive wear. Replace the shaft if
needed.
