NOTE:  If you choose to remove the piston seal or self-flush 
seals, you should have a new set on hand to install after 
cleaning. It is not recommended that you reinstall used 
piston or self-flush seals since they are likely to be 
scratched and damaged during removal and would not 
provide a reliable seal if reused. If you decide to remove the 
seals, use only the flanged end of the plastic seal removal 
tool supplied with the seal replacement kit and avoid 
scratching the sealing surface in the pump head. See 
Section 5.2.3 for seal replacement instructions. 

1.  Inspect the piston seal cavity in the pump head. Remove any foreign 

material using a cotton swab, or equivalent, and avoid scratching the 
sealing surfaces. Repeat for the self-flush housing. Be sure no fibers 
from the cleaning swab remain in the components. 

2.  The pump head, check valves, and self-flush housing may be further 

cleaned using a laboratory grade detergent solution in an ultrasonic 
bath for at least 30 minutes, followed by rinsing for at least 10 minutes 
in distilled water. Be sure that all particles loosened by the above 
procedures have been removed from the components before re-
assembly. 

CAUTION:  When cleaning check valves, be sure that the 
ball is not against the seat in the ultrasonic bath. This may 
destroy the precision matched sealing surface and the valve 
will not check. 

 

CAUTION:  If removing the check valves, keep them in the 
orientation shown below the entire time they are not 
installed in the pump head. The assemblies may fall apart, 
parts may be lost, and they may not operate properly when 
re-assembled.
