Procedure for replacing obsolete pump with
maintenance free, extended life compressor
Part Number 23031
Document Part Number 23033
DESCRIPTION
A maintenance-free, long life Hargraves compressor has been instituted as an
across the board replacement for the obsolete KNF pump in ADH–2A COM
Dehydrators. The advantages of the new compressor are:
•
Brushless motor for long life and zero maintenance.
•
Hargraves’ proprietary diaphragm material for longer life.
•
Higher airflow at pressures above 2 PSI, similar airflow below 2 PSI.
•
Smaller, lighter unit.
•
More efficient design requires less power to operate.
This procedure documents the steps required to perform a field upgrade from the
old pump to the new brushless unit.
