Assembly Instructions
• The diaphragm pump offers high volume delivery even at low air pressure.
• Air-operated double diaphragm pumps utilize a pressure differential in the air chambers to
alternately create suction and positive fluid pressure in the fluid chambers. The ball check insures
a positive flow of fluid.
• Pump cycling will begin as air pressure is applied and it will continue to pump and keep up with
the demand. It will build and maintain line pressure and will stop cycling once maximum line
pressure is reached (dispensing device closed) and will resume pumping as needed.
Before Each Use
⚠WARNING
 Inspect before each use. Before switching the air supply on, check hoses for any sign of wear,
leaks, or loose fittings. Replace as necessary.
 Secure pump, connections and all contact points to avoid vibration and generation of contact or
static spark.
 Pipe the exhaust to a safe remote location when pumping hazardous or inflammable materials.
 Verify the chemical compatibility of the pump wetted parts and the substance being pumped,
flushed or recirculated.
 Prevent unnecessary damage to the pump. Do not allow pump to operate when out of material for
long periods of time.
Operating Instructions
⚠WARNING
 Do not exceed the maximum inlet air pressure as stated on the pump model plate. EXCESSIVE
AIR PRESSURE. Can cause personal injury, pump damage or property damage.
 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.
 Static Spark Hazard. Sparks from static electricity can ignite flammable materials and vapors,
causing explosion resulting in severe injury or death. Ground pump and pumping system.
 The pumping system and object being sprayed must be grounded when it is pumping, flushing,
recirculating or spraying flammable 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, hoses and any object to which material is being pumped.
 Use the pump grounding screw terminal provided. Connect a suitable ground wire to a good earth
ground source.
 EXPLOSION HAZARD. Models containing aluminum wetted parts cannot be used with III.-
Trichloroethane, Methylene Chloride or other Halogenated Hydrocarbon solvents which may react
and explode.
