OPERATION
To start the pump, turn on the main
air supply.
Slowly
open the air regulator
until the pump runs smoothly.
Open the
dispensing
valve to allow air to be purged
from the system.
Allow
pump
to cycle
until fluid without
air pockets
flows from
dispensing
valve, then close dispensing
valve.
In a direct
supply
system,
with ade-
quate
air pressure
supplied
to the air
motor, the pump starts when the dispens-
ing valve
is opened
and stalls
against
pressure
when
dispensing
valve
is
closed.
In a circulating
system,
the
pump
runs
continuously
and slows
down
or
speeds
up as supply
demands
until the
air supply
is shut off.
Use the air
regulator
to control
pump
speed
and fluid
pressure.
Always
use
the lowest
pressure
required
to achieve
the desired
results.
Higher
pressures
will cause
pump
packings
to wear
pre-
maturely.
To reduce
the risk of serious
bodily
injury
or property
dam-
age,
NEVER
exceed
the
maxi-
mum
air or fluid
working
pres-
sure of the lowest
rated
system
component.
If the pump accelerates
rapidly
or is
running
too
fast,
stop
it immediately.
Check the fluid supply
and refill if neces-
sary.
Prime
the pump
to remove
all air
from the system
or flush
the pump
and
relieve
pressure.
Water
or even
moist
air can
cause
pump
to
corrode.
To
help
prevent
corrosion,
NEVER
leave the pump
filled
with water
or air.
After
normal
flushing,
flush
the pump
again
with
min-
eral spirits
or oil based
solvent,
relieve
pressure
and leave
min-
eral
spirits
in the
pump.
Be
sure
to follow
all
steps
of the
pressure
relief
procedure
warning.
MAINTENANCE
To reduce
the risk of serious
bodily
injury,
ALWAYS
follow
the
pressure
relief
procedure
warning
whenever
you stop the
pump
and
before
checking
or
repairing
any part of the system.
