After each use
Run pump for five minutes with clean water. These few minutes
of flushing are well spent: extend diaphragm life, minimize
chemical buildup throughout your spray system.
PUMP MAINTENANCE
After every 200 hours AND at season’s end
Inspect diaphragms for wear marks, swelling, and stretching.
See the diaphragm replacement instructions, below.
Check valves for spring fatigue and seat wear.
Change the oil- the crankcase oil capacity is in your pump
manual. Use a 30W non-detergent oil . Rotate the pump shaft
by hand while filling to evacuate air pockets. With pump level,
the crankcase is full when oil level reaches the indicator on the
transparent fill neck. Run pump for 10 minutes under
no load
conditions to evacuate remaining air pockets. Recheck oil level.
During first field run,
check oil color closely . If it should turn
milky, the diaphragms were not correctly seated.
Winter storage
Run pump for five minutes with clean water. Then, with suction
and discharge valves open and the tank empty, run pump five
minutes to ensure complete drainage of pump heads and lines.
A gallon of anti-freeze recirculated through the system and left
in place after shut down completes your winterizing. Allow
anti-freeze to replace any possible water in hoses and booms.
If a handgun is in the system, run anti-freeze through the hose
and handgun, returning the spray into the tank through the lid.
Two gallons of anti-freeze may be required to winterize systems
with handgun lines.

Replacing air dome diaphragm
Bleed off air pressure in the air dome. Remove the 13mm
bolts holding the assembly together. Use a flat head
screwdriver to remove the old diaphragm. Install the new
diaphragm and re-install air dome. See previous page for
air dome charging instructions.

Replacing diaphragms
Drain the crankcase. Slowly turn pump shaft by
hand until all oil is drained. Older AR30/50 pumps
without a drain plug require a head and diaphragm
to be removed to empty oil.
Remove the manifold: take care not to lose or
damage input/output port o-rings.
Head removal- repair one head at a time. Re-
move fasteners securing head to body- some pumps
use bolts (
fig. A ) others have nuts on mount studs
( fig. B ). You may need to lightly pry the head
cover with a flathead screwdriver to loosen.
Remove the old diaphragm. Top out the piston/
diaphragm assembly by turning the pump shaft.
Remove the diaphragm retaining nut (
fig. A ) If
the nut holds and the retaining bolt loosens from
the piston head, this creates no problem. (
Some
bolts have a hole ( fig. C ) to insert a 8” pin punch
and hold bolt when removing nut & washer. ) Using
a flathead screwdriver ( fig. B ) pry the diaphragm
from its seat.
Install the new diaphragm. If your model uses a
Diaphragm WITH support washer Diaphragm WITHOUT support washer
diaphragm support washer (see washer installa-
tion diagram , above) be certain it is installed as
illustrated. Pour 2
Tbsp
30W non-detergent oil
into lower diaphragm cavity. Tap new diaphragm
into seat groove with the handle of a screwdriver.
Reassemble retaining washer and nut as illus-
trated and re-assemble head and manifold.
Fill the crankcase with oil.
The crankcase oil
capacity is in your pump manual. Use a
30W
non-detergent oil
. Rotate the pump shaft by
hand while filling to evacuate air pockets. With
pump level, the crankcase is full when oil level
reaches the indicator on the transparent fill neck.
Run pump for 10 minutes under

tions to evacuate remaining air pockets. Recheck
oil level. During first field run,

were not correctly seated.
