Conductive Polypropylene Air Diaphragm Pumps are cost effective alternative to PVDF pumps in many applications requiring ATEX certification, high chemical resistance, resistance to ultraviolet radiation and high mechanical strength. Conductive Polypropylene AODD pumps should be considered as a possible substitute to PVDF pumps also due to restrictions in export of PVDF pumps to many countries …
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 …
For proper Diaphragm Pump selection understanding of fluids properties is mandatory. Fluid flow is highly dependent on the viscosity of fluids. Basically, viscosity is a resistance to the flow which must be taken into account during pump size selection. Viscosity of fluids can change under different conditions. We can divide liquids into following groups: • Newtonian …
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 …
Sodium hydroxide NaOH (common names – caustic soda, soda lye, white caustic, sodium hydrate) is one of the most commonly used industrial chemicals. It is very often used for pH control (to raise it) as it is very alkaline. The most used concentration of NaOH is 50%. The major consideration during pumping sodium hydroxide (caustic …
