AEC Whitlock PowdrPump™ Dense
Phase Conveyor

AEC's PowdrPump® conveyor is a low velocity, pneumatic conveying system designed to move to a wide variety of difficult powdered materials cleanly and efficiently. The finer the powder, the more effectively it works. Powered by compressed air, the conveyor moves large volumes of powder - up to 25 cu. ft./hr. with the 1" model and up to 100 cu. ft./hr. with the 2" model - at distances up to 200 feet. For applications requiring greater conveying rates, multiple units may be operated in sequence.

The conveying sequence begins when the material valve opens to allow powder to flow by gravity into a pressurizing chamber. The valve closes and injected compressed air pumps the powder, pushing it through the conveying line. This sequence is automatically repeated to "pump" the powder to its end use point. Four easy-to-operate timers control the conveying rate of the PowdrPump by varying the time for material filling and unloading of the pressurizing chamber.

• Low maintenance design featuring the air piston and material valve as the only moving parts--No lubrication or special tools required for normal periodic maintenance.
• Simple-to-operate controls to regulate powder conveying rate.
• Small conveying air requirement makes it economically feasible to use inert gas in hygroscopic and explosive material applications.
• Low conveying air velocity (1200-2000 ft./min.) creates minimal dusting of conveyed powders, minimal material degradation, and no need for exotic conveying lines to resist premature abrasion and wear.
• Slugs of materials are conveyed rather than individual particles so mixes are kept intact.
