◼ In the event of a diaphragm rupture material can be forced out of the air exhaust muffler.
◼ Pipe the exhaust to a safe remote location when pumping hazardous or inflammable materials.
WARNING! HAZARDOUS PRESSUREcan result in serious injury or property damage. Do not service or
clean pump, hoses or dispensing valve while the system is pressurized.
WARNING! 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.
CAUTION! Verify the chemical compatibility of the pump wetted parts and the substance being pumped,
flushed or recirculated.
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.
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.
OPERATING INSTRUCTIONS
AIR AND LUBE REQUIREMENTS
WARNING! EXCESSIVE AIR PRESSURE CAN CAUSE PUMP DAMAGE, PERSONAL INJURY OR
PROPERTY DAMAGE.
◼ The air delivery pipe should be big enough to ensure the air needed.
◼ Air pressure must not exceed 115 PSI (8 BAR).
◼ A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is
no lubrication required other than the O-ring lubricant which is applied during assembly or repair.
◼ If lubricated air is present, make sure that is compatible with the O-rings in the air motor section of the
pump.
1. Always flush the pump with a solvent compatible with the material being pumped if the material being
pumped is subject to “setting up” when not in use for a period of time.
2. Disconnect the air supply from the pump if it is to be inactive for a few hours.
3. Disconnect the air supply from the pump if it is not in use.
4. The material supply tubing should not be too small or restrictive. Be sure not to use hose which might
collapse.
5. When the diaphragm pump is used in a forced-feed (flooded inlet) situation, it is recommended that a
“Check Valve” be installed at the air inlet.
6. Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration.
MAINTENANCE
◼ Provide a clean work surface to protect sensitive internal moving parts from contamination from dirt and
foreign matter during service disassembly and reassembly.
◼ Keep good records of service activity and include pump in preventive maintenance program.
◼ Before disassembling, empty captured material in the outlet manifold by turning the pump upside down to
drain material from the pump
