Air Operated Pumps

Product Details:

• An AODD pump is a type of positive displacement pump that uses compressed air as a power source.
• The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously.
• This back-and-forth motion forces liquid out of one chamber and into the discharge piping while the other chamber is being filled with liquid at the same time.
• These pumps use reciprocating elastomeric diaphragms and check valves to pump fluid.
• The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.

• No electrical motor - non sparking.
• No mechanical seals or gland packing.
• The pumps can run dry indefinitely without damage.
• Safe for use in hazardous / explosive environments.
• Variable flow - simply regulate the inlet air supply to adjust the pump flow from zero to max.
• If discharge is clogged or closed pump stops immediately; no power consumed, no wear. By opening discharge, flow starts automatically.
• Self-priming from a dry start up to 6 meters without a foot valve.
• Operates submerged or with flooded suction.
• No close fitting, sliding or rotating parts so can handle a wide range of fluids with high solid content.
• Gentle non-shearing action.
• Quick assembly and disassembly with split clamp bands.
• Pumps are light weight and portable.
