2.3 - TEMPERATURE LIMITATIONS
Do not exceed the recommended operating temperatures of the pump. The maximum temperature limitations
are based on mechanical stress only and various liquids/chemical may reduce the maximum safe operating
temperatures of the pumps.
Diaphragms : PTFE can operate continuously between -30°C and +85ºC.
Pump housing : PP (polypropylene) can be used in the interval ±0°C and +85°C.
Aluminium can be used in the same interval as the diaphragms.
2.4 - SOUND LEVEL RATINGS
The following values were measured from an AD60, pumping water at 7 bar air pressure and fully open inlet
and discharge ports.The readings were made at a distance of 1 (one) metre on the same level as the pump :
• Front
79.5 dB(

)
• Left
75.5 dB(

)
• Right
74.9 dB(

• Behind

2.5 - DRY RUNNING
The AD-pump can normally run dry without damaging the pump components. For extended periods of dry
running, however, a certain wear of the shaft bushing will occur.
2.6 - REST VOLUMES
If the pump runs until it has emptied the suction line the following rest volumes will remain in the pumps :
• AD15
45 ml
• AD30
45 ml
• AD60
90 ml
• AD120
200 ml
If the product discharge line is closed the following volumes will remain in the pump :
• AD15
90 ml
• AD30
90 ml
• AD60
180 ml
• AD120
400 ml
