EXCESSIVE AIR PRESSURE

STATIC SPARK

HAZARDOUS MATERIALS

HAZARDOUS PRESSURE

WARNING

 EXCESSIVE AIR PRESSURE. Can cause personal 

injury, pump damage or property damage.

 

y

Do not exceed the maximum inlet air pressure as stated on 
the pump model plate.

 

y

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 dispensing 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.

 

y

Sparks can ignite flammable material and vapors.

 

y

The pumping system and object being sprayed must be 
grounded when it is pumping, flushing, recirculating or 

spraying flammable materials such as paints, solvents, lac-

quers, etc. or used in a location where surrounding atmo-

sphere is conducive to spontaneous combustion. Ground 

the dispensing valve or device, containers, hoses and any 

object to which material is being pumped.

 

y

Secure pump, connections and all contact points to avoid 
vibration and generation of contact or static spark.

 

y

Consult local building codes and electrical codes for specific 
grounding requirements.

 

y

After grounding, periodically verify continuity of electrical 
path to ground. Test with an ohmmeter from each compo-

nent (e.g., hoses, pump, clamps, container, spray gun, etc.) 

to ground to ensure continuity. Ohmmeter should show 0.1 

ohms or less.

 

y

Submerse the outlet hose end, dispensing valve or device 
in the material being dispensed if possible. (Avoid free 

streaming of material being dispensed.)

 

y

Use hoses incorporating a static wire.

 

y

Use proper ventilation.

 

y

Keep inflammables away from heat, open flames and 
sparks.

 

y

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.

 

y

In the event of a diaphragm rupture, material can be forced 
out of the air exhaust muffler.

 

y

Pipe the exhaust to a safe remote location when pumping 
hazardous or inflammable materials.

 

y

Use a grounded 1” minimum ID hose between the pump 
and the muffler.

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.

 

y

Disconnect air supply line and relieve pressure from the 
system by opening dispensing valve or device and / or care-

fully and slowly loosening and removing outlet hose or pip-

ing from pump.

WARNING

 HAZARDOUS MATERIALS. Can cause serious in-

jury or property damage. Do not attempt to return a pump 

to the factory or service center that contains hazardous ma-

terial. Safe handling practices must comply with local and 

national laws and safety code requirements.

 

y

Obtain Material Safety Data Sheets on all materials from 
the supplier for proper handling instructions.

WARNING

 EXPLOSION HAZARD. Models containing alu-

minum parts cannot be used with 1,1,1-trichloroethane, 

methylene chloride or other halogenated hydrocarbon sol-

vents which may react and explode.

 

y

Check pump motor section, fluid caps, manifolds and all 
wetted parts to assure compatibility before using with sol-

vents of this type.

WARNING

 MISAPPLICATION HAZARD. All fluid contact ma-

terials must be FDA compliant and meet the United States 

Code of Federal Regulations (CFR) Title 21, Section 177.

CAUTION

 Verify the chemical compatibility of the pump 

wetted parts and the substance being pumped, flushed or 

recirculated. Chemical compatibility may change with tem-

perature and concentration of the chemical(s) within the 

substances being pumped, flushed or circulated. For spe-

cific fluid compatibility, consult the chemical manufacturer.

CAUTION

 Maximum temperatures are based on mechani-

cal stress only. Certain chemicals will significantly reduce 

maximum safe operating temperature. Consult the chemi-

cal manufacturer for chemical compatibility and tempera-

ture 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 re-

quired.

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.

 

y

Suction and discharge connections should be flexible con-
nections (such as hose), not rigid piped, and should be com-

patible 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.

 

y

Disconnect air line from pump when system sits idle for 
long periods of time.

CAUTION

 Use only genuine ARO replacement parts to as-

sure compatible pressure rating and longest service life.

NOTICE

 RE-TORQUE ALL FASTENERS BEFORE OPERA-

TION.

 

Creep of housing and gasket materials may cause fasteners

 

to loosen. Re-torque all fasteners to ensure against fluid

 

or air leakage.

NOTICE

 Replacement warning labels are available upon 

request:  “Static Spark & Diaphragm Rupture” pn \ 94080.

NOTICE

 For best sealing results, use a standard sanitary 

clamp style gasket of a flexible material such as EPDM, 

Buna-N, fluoroelastomer, or silicone.

NOTICE

 SANITIZE THE PUMP BEFORE FIRST USE. It is the 

user’s responsibility to properly sanitize the pump before 

first use. It is up to the user whether this will include disas-

sembling and cleaning individual parts or simply flushing 

pump with a sanitizing solution.

WARNING

= Hazards or unsafe practices which could 

result in severe personal injury, death or 

substantial property damage.

CAUTION

=

Hazards or unsafe practices which could 

result in minor personal injury, product 

or property damage.

NOTICE

= Important installation, operation or mainte-

nance information.

READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
