Cleaning the DP-3000
Tools and Materials Needed:
 Soft cloth
 Scribe
 Cleaning step bottle brush (provided with DP-3000)
 Mild solvent or isopropyl alcohol (IPA).
 Compatible solvent for your fluid (see the MSDS for fluid compatibility)
1. Wipe off the piston with a soft cloth and mild solvent or IPA. Clean the luer clamp block
with IPA.
2. Unscrew the priming chamber and lift it off of the top of the pumping chamber.
3. Use the seal removal tool (P/N 48-8105) to remove all of the seals and o-rings from the
priming and pumping chambers.
4. Remove the prime port from the side of the priming chamber.
5. If your priming chamber is equipped with the plastic prime port, discard the prime port
and replace it with a new one.
6. If your priming chamber is equipped with the metal luer prime port, save it and clean it
with the rest of the parts.
7. Using the cleaning step brush and solvent, clean the pumping chamber, the priming
chamber, the metal luer prime port (if one is present), the pumping chamber seal, and
the o-rings.
8. Replace the o-rings as recommend.
9. Replace the seal.

CAUTION!
Do NOT use acetone or isopropyl alcohol (IPA) to clean the seals or o-
rings. These solvents will cause seal degeneration that results in fluid leakage. Many
solvents will cause the o-rings to swell so that the pumping chamber does not fit
correctly onto the pump. Therefore, you should NOT soak the o-rings in solvent when
cleaning the pump.
 Also, when using the DP-3000 with encapsulants and underfill materials, you MUST
change the seal at least once a week. These materials may cause the seals to leak,
allowing fluid into the feed screw, upper body and piston areas.
10. Place the pumping and priming chambers into an ultrasonic cleaner.
11. Clean and inspect the interior of the pumping and priming chambers to make sure that all
residual material has been removed.
12. When you are satisfied that all of the parts are clean, remove and dry, reassemble the
pump chamber, and reinstall the DP-3000.
