Danger!
Dangerous liquids can damage your health and the environment.
• When handling dangerous or toxic liquids you have to waer goggles and protective clothing.
• Before starting the pump check that the medium being pumped is compatible. Changes of temperature,
concentrations or combinations of chemicals may vary resistance of material. Always consult Material
Safety Data Sheets and Engineering Resistance Tables for chemical compatibility.
• If a diaphragm ruptures, the pumped liquid can enter the air side of the pump and exit through the air
exhaust (muffler). If a diaphragm rupture occurs immediately stop the pump, close suction- and discharge
lines and have pump repaired.
• When the fluid source is at a higher level than the pump (flooded suction), the exhaust should be piped to a
higher level than the fluid source. After operation of pump it should be possible to close the suction line by
means of e.g. a ball valve. Running out of the container can be effectively avoided in case a damage occurs
at the piping system or at the pump.
Danger!
Do not clean or service pump, hoses or dispensing valves when the system is pressurized – serious injury
may result.
Disconnect air supply line and relieve pressure from the system prior to disassembly.
Warning!
Maximum temperatures are based on mechanical stress only.
Certain chemicals will significantly reduce maximum safe operating temperature. Consult engineering guides
for chemical compatibility and temperature limits.
Always use minimum air pressure when pumping at elevated temperatures.
Warning!
Excessive air pressure can cause pump damage, personal injury or property damage.
Warning!
Excessive positive suction pressure can cause pump damage. The maximum positive suction pressure must
not exceed 0.6 bar.
Warning!
Pump must be reassembled properly after maintenance.
Caution!
Do not use the pump for the structural support of the piping system. Be certain the system components are
supported to prevent stress on the pump parts. The pump must be installed free of tension.
Flexible connections will avoid damage to piping due to vibration.
Caution!
The characteristic feature of double diaphragm pumps is a pulsating volume flow.
For reduction use a pulsation dampener if necessary.
