AIR
AND LUBE REQUIREMENTS
WARNING EXCESSIVE AIR PRESSURE. Can cause perĆ
sonal injury, pump damage or property damage. Do not exĆ
ceed maximum inlet air pressure as stated on air motor plate.
DFiltered and oiled air will allow the pump to operate more efficiently
and yield a longer life to operating parts and mechanisms.
DA filter capable of filtering out particles larger than 50 microns
should be used on the air supply. In most applications there is no
lubrication required other than the ``O" ring lubricant which is apĆ
plied during assembly or repair.
DWhen lubricated air is necessary, supply the air lubricator with a
good grade of SAE 90 wt. nonĆdetergent oil and set the lubricator to
a rate not to exceed one drop per minute.
TRANSPORT AND STORAGE
DStore in a dry place, do not remove product from box during storĆ
age.
DDo not remove protection caps from inlet and outlet prior to installaĆ
tion.
DDo not drop or damage box, handle with care.
INSTALLATION
DSecure the diaphragm pump legs to a suitable surface to insure
against damage by excessive vibration.
DPump cycle rate and operating pressure should be controlled by
using an air regulator on the air supply.
DThe outlet material volume is governed not only by the air supply
but also by the material supply available at the inlet. The material
supply tubing should not be too small or restrictive. Be sure not to
use hose which might collapse.
DUse flexible connections (such as hose), at the suction and disĆ
charge, these connections should not be rigid piped and must be
compatible with the material being pumped.
DInstall a ground wire where applicable.
OPERATION
STARTĆUP
1. Turn pressure control knob until motor starts to cycle.
2. Allow pump to cycle slowly until it is primed and all air is purged
from the fluid hose or dispensing valve.
3. Turn off dispensing valve and allow pump to stall, check all fittings
for leakage.
4. Adjust the regulator as required to obtain desired operating presĆ
sure and flow.
SHUTDOWN
DIt is good practice to periodically flush entire pump system with a
solvent that is compatible with the material being pumped, espeĆ
cially if the material being pumped is subject to "settlingĆout" when
not in use for a period of time.
DDisconnect the air supply from the pump if it is to be inactive for a
few hours.
SERVICE
DKeep good records of service activity and include pump in prevenĆ
tive maintenance program.
DUSE ONLY GENUINE ARO REPLACEMENT PARTS TO ASSURE PERĆ
FORMANCEAND PRESSURE RATING.
DContact your local authorized ARO Service Center for parts and
customer service information. Refer to page 2.
