This pump is pressurized
internally with air pressure
during operation. Always
make certain that all bolting
is in good condition and
th at all of the co rr ect
bolting is reinstalled during assembly.
Before pump operation,
i n s p e c t a l l g a s k e t e d

When used for toxic or
aggressive uids, the pump
should always be ushed
clean prior to disassembly.
Be fore ma in te nance or
repair, shut off the com-
pressed air line, bleed the
pressure, and disconnect
the air line from the pump.
The discharge line may be
pressurized and must be bled of its pressure.
Take action to prevent static
sparking. Fire or explosion
can result, especially when
handling ammable liquids.
