Maintenance required
All Heidolph Vacuum Pumps require cleaning and maintenance to clean out chemical build up from
solvents not distilled. We recommend a weekly rinse, or more depending on use, with Acetone or
equivalent to break up and clean out solvent.
Disconnect all tubes and switch ON the pump. Slowly drip Acetone into the INLET nozzle of the
operating pump. The cleaning solvent will be distributed through the pump valves and along the
diaphragms, removing remains. Please ensure that your cleaning solvent exiting the pump is
collected in a vessel at the OUTLET nozzle.
ATTENTION:
Be careful not to use too large of a quantity of cleaning solvent in the pump, which
will cause damage to the pump diaphragms
