Exchanging the Pump Seals and Seal Wear-in Procedure
Seal Wear-in Procedure
1 Place a bottle with 100 ml of Isopropanol in the solvent cabinet and place
the tubing (including bottle head assembly) of the pump head that is
supposed to be worn-in into the bottle.
2 If an AIV is installed, screw the Adapter AIV to solvent inlet tubes (p/n
0100-1847) to the AIV and connect the inlet tube from the bottle head
directly to it.
3 Connect the restriction capillary (5022-2159) to the outlet of the EMPV.
Insert its other end into a waste container.
4 Turn the system in purge mode and purge the system for 2 minutes with
isopropanol at a flow rate of 2 ml/min.
5 Turn the system to Standard Mode, set the flow to a rate adequate to achieve
a pressure of 350 bar. Pump 15 min at this pressure to wear in the seals.
The pressure can be monitored at your analog output signal, with the
Instant Pilot, data system or any other controlling device connected to your
pump.
6 Turn OFF the pump, slowly disconnect the restriction capillary from the
EMPV to release the pressure from the system. Reconnect the capillary
going to the flow sensor and the connecting tube from solvent selection
valve to the AIV.
7 Rinse your system with the solvent used for your next application.
NOTE
This procedure is required for standard seals only (5063-6589), but it will definitely damage
the normal phase application seals (0905-1420).
