Low Noise Air Operated Diaphragm Pump For Alkali And Various
Organic Solvents
Air Operated Diaphragm (AOD) Pumps were designed to resolve
numerous problems that pumpers’ face on a job site. Whether you
have limited space, are moving fluids with mixed solids or
compositions, or require a safe priming pump system for your job,
our AOD pumps provide a portable solution to get the job done.
Operating through a dual-diaphragm fluid chamber, positive
displacement creates an air vacuum, initiating quick priming with
minimal effort. Once primed, air operated diaphragm pumps are
capable of passing up to 1-¼ inch solids (up to 90% solid
composition) and highly viscous fluids with ratings exceeding
25,000 cPs. AOD Pumps’ fluid handling, portability and durability
make them a versatile pump for any job application.
Air Operated Diaphragm Pump Advantage
1. No irrigation water, suction up to 5 meters, head up to 70
meters, the outlet pressure > 7bar
2. Wide flow and good performance, which allows the maximum
particle diameter of 10 mm. Pumping mud, impurities, minimal wear
and tear on the pump
3. Head, flow through the valve open to realize the stepless
adjustment (pressure regulator between 1-7bar)
4. The pump has no moving parts, no seals, diaphragms exhausted
medium and pump running parts, working medium is completely
separated from the transmission medium does not leak out. So
pumping toxic, volatile or corrosive media, will not cause
environmental pollution and danger to personal safety.
5. Do not have electricity, flammable and explosive places safe and
reliable.
6. Can be immersed in the medium.
7. Easy to use, reliable, open stop simply open and close the gas
valve, even for long periods because of accident or sudden stop
running without media will not result in damage to the pump, once
the overload, the pump will automatically shut down, with
self-protection performance, when the load is back to normal, and
can automatically start running.
