EXCESSIVE AIR PRESSURE
S TATIC SPARK

HAZARDOUS MATERIALS
HAZARDOUS PRESSURE

WARNING

 

EXCESSIVE AIR PRESSURE. Can cause per- 

sonal injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as 
stated on the pump model plate.
Be sure material hoses and other components are able 
to withstand fluid pressures developed by this pump. 
Check all hoses for damage or wear. Be certain dispens-
ing device is clean and in proper working condition.

WARNING

 

STATIC SPARK. Can cause explosion 

resulting in severe injury or death. Ground pump and 
pumping system. 
Sparks can ignite fl ammable material and vapors.  
The pumping system and object being sprayed must be 
grounded when it is pumping, fl ushing, recirculating or 
spraying fl ammable materials such as paints, solvents, 
lacquers, etc. or used in a location where surrounding 
atmosphere is conducive to spontaneous combustion. 
Ground the dispensing valve or device, containers, hos-
es and any object to which material is being pumped.
Secure pump, connections and all contact points to 
avoid vibration and generation of contact or static spark.
Consult local building codes and electrical codes for 
specifi c grounding requirements.
After grounding, periodically verify continuity of 
electrical path to ground. Test with an ohmmeter 
from each component (e.g., hoses, pump, clamps, con-
tainer, spray gun, etc.) to ground to insure continuity. 
Ohmmeter should show 0.1 ohms or less.
Submerse the outlet hose end, dispensing valve or 
device in the material being dispensed if possible. 
(Avoid free streaming of material being dispensed.)
Use hoses incorporating a static wire.
Use proper ventilation.
Keep infl ammables away from heat, open fl ames and 
sparks.
Keep containers closed when not in use.

WARNING

 

Pump exhaust may contain contaminants. 

Can cause severe injury. Pipe exhaust away from work 
area and personnel.
In the event of a diaphragm rupture, material can be 
forced out of the air exhaust muffl

  er.

Pipe the exhaust to a safe remote location when 
pumping hazardous or infl ammable materials.
Use a grounded 3/4” minimum i.d. hose between the 
pump and the muffl

  er.

WARNING

 

HAZARDOUS PRESSURE. Can result in 

serious injury or property damage. Do not service 
or clean pump, hoses or dispensing valve while the 
system is pressurized.
Disconnect air supply line and relieve pressure from 
the system by opening dispensing valve or device and 
/ or carefully and slowly loosening and removing out-
let hose or piping from pump.

WARNING

 

HAZARDOUS MATERIALS. Can cause 

serious injury or property damage. Do not attempt 
to return a pump to the factory or service center that 
contains hazardous material.

Safe handling practices must comply with local and 
national laws and safety code requirements.
Obtain Material Safety Data Sheets on all materials 
from the supplier for proper handling instructions.

WARNING

 

EXPLOSION HAZARD. Models containing 

aluminum wetted par ts cannot be used with 
1,1,1-trichloroethane, methylene chloride or other 
halogenated hydrocarbon solvents which may react 
and explode.
Check pump motor section, fl uid caps, manifolds and 
all wetted parts to assure compatibility before using 
with solvents of this type.

CAUTION

 Verify the chemical compatibility of the 

pump wetted parts and the substance being pumped, 
flushed or recirculated. Chemical compatibility may 
change with temperature and concentration of the 
chemical(s) within the substances being pumped, 
fl ushed or circulated. For specifi c fl uid compatibility, 
consult the chemical manufacturer.

CAUTION

 Maximum temperatures are based 

on mechanical stress only. Certain chemicals will 
significantly reduce maximum safe operating 
temperature. Consult the chemical manufacturer for 
chemical compatibility and temperature limits. Refer 
to PUMP DATA on page 1 of this manual.

CAUTION

 Be certain all operators of this equipment 

have been trained for safe working practices, 
understand it’s limitations, and wear safety goggles / 
equipment when required.

CAUTION

 Do not use the pump for the structural 

support of the piping system. Be certain the system 
components are properly supported to prevent stress 
on the pump parts.
Suction and discharge connections should be fl exible 
connections (such as hose), not rigid piped, and should 
be compatible with the substance being pumped.

CAUTION

 Prevent unnecessary damage to the 

pump. Do not allow pump to operate when out of 
material for long periods of time.
Disconnect air line from pump when system sits idle 
for long periods of time.

CAUTION

 

Use only genuine ARO replacement parts 

to assure compatible pressure rating and longest 
service life.

NOTICE

 RE-TORQUE ALL FASTENERS BEFORE 

OPERATION. Creep of housing and gasket materials 
may cause fasteners to loosen. Re-torque all fasteners 
to insure against fl uid or air leakage.

NOTICE

 Replacement warning labels are available 

upon request: Static Spark” (936161) and Diaphragm 
Rupture” (931221).
