Pneumatic Operated AODD Pump / Membrane Air Powered Diaphragm Pump

AODD Pump Introduction

AODD Pump is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side. This pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc.

WHY AODD Pump

Air-operated double diaphragm (AODD) pumps offer a number of advantages that make them perfect for an almost endless variety of uses. AODD pumps:

• Can easily and efficiently handle anything from water to 90% solids
• Offer the ability to vary flow and discharge pressure up to 125 psi with a simple adjustment of the air supply
• Enable one pump to be used for numerous applications, eliminating the need for expensive motor drives and critical sizing calculations
• Can pass even large, shear-sensitive solids without degradation or heat buildup transferred to pumped medium
• Are able to run dry without damage to pump
• Can operate "on demand systems" without expensive pressure relief and bypass accessories
• Will not froth or separate medium
• Are capable of pumping as slow as one gallon per minute

AODD Pump Parameters

Air Driven Double Diaphragm Pump Advantage

• No irrigation water, suction up to 5 meters, head up to 70 meters, the outlet pressure > 7bar
• Wide flow and good performance, which allows the maximum particle diameter of 10 mm. Pumping mud, impurities, minimal wear and tear on the pump
• Head, flow through the valve open to realize the stepless adjustment (pressure regulator between 1-7bar)
• 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.
• Do not have electricity, flammable and explosive places safe and reliable.
• Can be immersed in the medium.
• 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.
• Simple structure, less wearing parts, the pump is simple to install, easy maintenance, pumping medium can not come into contact with the valve and coupling lever and other moving parts, unlike other types of pumps due to the rotor, piston, gear, vane leaving other parts of the wear performance of gradual decline
