Repairing the Pump
Installing the Continuous Seal Wash Option
1 Route the wash inlet tube into a bottle filled with a mixture of distilled water
and isopropanol (90/10) and place the bottle above the pump (hydrostatic
pressure) in the solvent cabinet.
2 Route the outlet of the wash tube into a waste container.
3 The flow rate should be set to approximately 20 drops/minute. Use the
velocity regulator attached to the wash tube to regulate the flow rate.
NOTE The seals should never run dry. Running dry will significantly reduce the
lifetime of the seals.
