Cleaning the Pump Cartridge

Cleaning the Pump Cartridge
Introduction Cleaning of the pump cartridge and parts should be done thoroughly. It is critical that
all material is removed from all surfaces, particularly interior passages and threads.
Allowing partially cured material to remain on threads, in or on any other surface can
cause seizing of parts and other damage.
To avoid damage to machined and polished surfaces, do not use any sharp edged
implements.
The pump support kit contains pipe cleaners, cotton swabs and plastic bottle brushes
to facilitate cleaning.
Interior surfaces are considered clean when a fresh pipe cleaner or cotton swab
remains clean after being pushed through the passage.
Attention
HAZARDOUS MATERIALS. OBSERVE THE APPLICABLE MATERIAL SAFETY
DATA WARNINGS FOR CLEANING MATERIALS.
Attention
CAUTION. Be sure to use only the solvents recommended by the material
manufacturer for cleaning the pump.
Procedure Reference Figure 7 and Figure 8 when performing the following:
1. Gently clean the inside of the cartridge in a solvent suitable for removal of mate-
rial in pump. Cotton swabs and pipe cleaners immersed in the cleaning solvent,
are recommended for cleaning.
2. Use a pipe cleaner saturated with solvent to push the material from the feed tube
assembly. Repeat the procedure, using a clean pipe cleaner each time, until all
traces of material have been removed.
3. Clean the needle holder nut, washer, needle, and threads of the leadscrew.
4. Using denatured alcohol and a cotton swab, clean the bore of the cartridge hous-
ing and wipe down the outside of the housing.
5. Using a shop wipe and solvent, clean the leadscrew, making sure to remove all
traces of material from between the threads.
