Air-operated double diaphragm pumps are a versatile option for a variety of applications. Some of the key features of diaphragm pumps are:
No rotary or sliding seals in contact with the pumped liquid, reducing maintenance costs and allowing them to run dry without causing any damage.
Speed is varied by the air inlet, so no variable speed drives are required and the output is infinitely variable.
The pump discharge pressure can’t be more than the air pressure, so pressure relief valves in the pipeline aren’t normally required.
Suctions lifts of 20 feet or more are possible, with the pump being self-priming.
Diaphragm pumps can handle some of the most viscous of fluids -including peanut butter, which at 250,000 times more viscous than water is notoriously one of the most difficult substances to pump!
