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.
N O T E The seals should never run dry. Running dry will significantly reduce the
lifetime of the seals.
