Recommendations for New Piston Seals
When
When new piston seals have been installed
TIP
The actions recommended in this section directly influence pump
performance and the piston seal life cycle.
Items required
•
nanoViper™ capillary (length: 750 mm, inner diameter: 75 µm)
•
Isopropanol
•
Solvent suitable for your application
Recommendations
Allow new piston seals to run in.
To run in new piston seals, follow these steps:
1. Purge the pump. For 15 minutes, apply a purge flow of
approximately 1.3 mL/min using isopropanol.
2. Install the nanoViper capillary on the pump outlet. Guide the free
end of the capillary to the waste container.
3. For 30 minutes, apply a flow of approximately 2.0 mL/min using
isopropanol to generate a backpressure of approximately 80 MPa.
4. Turn off the pump flow and wait until the system pressure is down
to zero.
