Indoor Air Quality (IAQ) – air quality within and around buildings and structures plays is of utmost importance not only for employees well-being and ability to work but also for the proper operation of Air Operated Diaphragm Pumps (like other pneumatic and electronic equipment). Temperature, humidity, amount of outside air, mold on air, airborne contaminants …
Diaphragms are one of the most important elements of Air Operated Double Diaphragm Pump. They separate the wetted side (fluid side) of the pump from the non-wetted part (air side). Any diaphragm failure, rupture may result in fluid ingress into the non-wetted part of the pump. This may cause serious consequences – the destruction of …
It is not uncommon to use too small air supply line when installing an Air Operated Diaphragm pump. Overlooking restrictions installed along the line, which reduce volume of the flowing air is another frequent mistake. It happens, that diameter of the airline directly connected to the pump is correct. However, on the length of the …

As a rule of thumb, the start-up pressure of Air Operated Diaphragm Pumps should be set at 2,0 bar. Then, manually using air valve increases to the required maximum pressure. Or, automatically by utilizing installed on air supply line Slow Start Valve. Starting Air Diaphragm Pump at the full, or too high air pressure creates …
Cavitation is a common problem in pumps, including Air Operated Diaphragm pumps. Cavitation can cause significant damage to the AODD pump, which in turn can lead to the spilling of pumped fluid and potential risk to installation, facility and personnel. What is cavitation? Cavitation is an occurrence in which rapid changes of pressure in a …
