6.8 Bulk-14 Pump Replacement
Part No.
Installation Instructions:
Note: Disconnect power from unit.
Note: The pump must be “Hot” to properly disassemble and replace pump. Use heat gun to heat the pump before
removal. Take care to ensure your safety. Gloves, safety glasses and protective clothing should be worn, when
handling heated parts.
Note: When replacing o-ring seals, lubricate with Krytox lubricant.
1. Turn melt unit on its side to gain access to the pump.
2. Using a ¼” hex wrench, remove the 2 bolts from the pump.
3. The pump needs to be lifted up to release the alignment pins from the tank approx 1/10” and then moved away
from the motor.
4. The drive coupler will disengage as the pump is removed.
5. Use care to insure that the 3 balls and springs on the coupler are kept intact. If either are lost a replacement
coupler will be required.
6. After the pump has been removed, remove the 2 o-rings from the tank and clean the surface of the tank with the
material supplied.
7. Replace the o-rings with the new ones supplied being sure to apply the lube provided with the pump.
8. Remove the drive coupler from the pump shaft using a 1/8” hex wrench and install onto the shaft of the new
pump. Use care to insure that the setscrew is aligned with the flat on the pump shaft but not tight at this point.
9. Put the pump back into position on the tank using caution not to disturb the 2 o-rings on the tank. Rotate the
pump shaft to align the 2 halves of the coupler (check to see that all 3 balls and springs are in place) and allow
the pump to move into place.
10. When the pump is in place it will drop to the tank as the pins align with the holes on the tank.
11. Using the 2 bolts removed first bring them down snug then tight.
12. Slide the coupler into position and tighten the setscrew to lock on to the shaft.
13. Check coupler alignment.
14. If coupler is misaligned, use a 5/16” wrench and loosen the 4 screws on the motor just enough to allow the
motor to be pushed into position.
15. Retighten the screws on the motor.
16.
Turn tank back to normal position and resume operation.
