AODD Pumps
Are AODD pumps safe for use in explosive environments?
Yes, because they are operated by air and do not require an electric motor, AODD pumps are inherently safe and free of electrical hazards, making them ideal for hazardous and explosive zones.
Can the AODD pump run dry without being damaged?
One of the key benefits of Alpha Global’s AODD pumps is their ability to run dry indefinitely without causing any damage to the diaphragms or internal components.
How do you control the flow rate of an AODD pump?
The flow rate can be easily regulated by simply adjusting the air supply pressure or the volume of air entering the pump using an air regulator valve.
What is the maximum flow rate available in your AODD range?
Our AODD pumps come in various sizes from 1/2″ to 2″, with the largest model offering a maximum flow rate of 586 LPM (Liters Per Minute).
What materials are your diaphragms made from?
Depending on the chemical compatibility needed, we offer diaphragms in Teflon (PTFE), Neoprene, Santoprene, and Viton to handle various corrosive and abrasive fluids.
