DISASSEMBLY AND CLEANING
CLEANING THE PICK-UP ASSEMBLY
If a pickup tube assembly must be used for a different color or if,
for some other reason, it becomes necessary to clean the coloring from
the inside of a pickup assembly, the following steps will make this
potentially messy job easier.
1. Disconnect tubing from the process machine.
2. With the pump tube still installed in the pump head, run the pump in reverse until no more
color flows from the tubing assembly.
3. Once this is done and you are assured of a continuous air passage through the tubing, the
tubing assembly should be removed from the pump head and color container and placed
in a large utility sink. Place one end of the tubing assembly into the spigot opening and
turn on the hot water SLOWLY. Once you can see water flowing from the other end of the
tubing assembly, leave the water running for about 10 minutes. This should be sufficient
time to clean all remaining traces of liquid color from the tube. BE PATIENT. HOT WATER
AND TIME WILL DO THE JOB FOR YOU.
4. A copper pickup lance can be cleaned in the same manner.
SIX (6) ROLLER PUMP HEAD
1. Remove the clear cover disk.
2. Using an Allen wrench, remove the two recessed screws holding the pump head to the
control housing. The pump head may now be removed by simply pulling it away from the
motor shaft.
3. To remove the roller set, simply push it out of the outer pump head housing.
4. Once disassembled, clean all parts if necessary with soap and water. Reassemble and re-
install in reverse order.
NOTE: DO NOT LUBRICATE ANY PUMP HEAD PARTS. The pump works best when
totally DRY with NO lubrication. Since the center drive roller relies on friction to drive the 6
tube compression rollers, any lubrication such as Liquid Color contamination will interfere
with proper operation.
