Replacing a Pump Piston Seal and Piston Rinse Seal

A damaged seal allows leakage past the piston, as well as leakage from the
piston seal wash housing. The pump may be difficult to prime, flow rates may
be unstable, and there may be baseline noise.

Preparation

1. Rinse the pump flow path with deionized water. Direct the flow to waste by

opening the waste valve on the secondary pump head (see

Figure 5-10

). To

open the valve, turn the knob one-quarter to one-half turn counterclockwise.

2. After rinsing, close the waste valve.

3. Close the eluent valve from the Dionex ICS-1100 Control panel in

Chromeleon.

4. To prevent contamination of pump parts, put on a pair of rubber gloves before

disassembling the pump head.

Removing the Head and Piston

1. Turn off the main power switch, to ensure that you do not unintentionally start

the Dionex ICS-1100.

2. Disconnect all tubing connections to the pump head.

3. Locate the open-end wrench (P/N 014605) provided in the Dionex ICS-1100

Ship Kit (P/N 057905). Use the wrench to remove the two acorn nuts (see

Figure 5-7

) from the pump head.

4. Slowly pull the head and allow it to separate from the housing. Carefully

disengage the head from the piston by pulling the head straight off and away
from its mounting studs.

Lateral motion while disengaging the pump head from the piston may
break the piston.

Un mouvement latéral pendant la séparation de la tête et du piston
peut casser le piston.

Vermeiden Sie Seitwärtsbewegungen, wenn Sie den Kopf vom Kolben
lösen. Andernfalls kann der Kolben brechen.
