Flap Valve AODD Pump

• Perfect For Handling Line-size Solids
• Large flow area to allow up-to-line-size solids to pass directly through the pump
• Bottom discharge design helps prevent these solids from settling in the unit
• Eliminate common issues associated with ball valve pumps, where large solids get stuck in the suction manifold or small solids settle in the outer chamber, affecting performance
• Quick Access To Serviceable Components
• Removable Clean-Out Caps: By simply removing the six bolts securing the clean-out cap in place, you can access and clear simple clogs without disassembling the entire pump.
• Modular Check Valve Access: With the clean-out cap removed, flap valves can be inspected and/or replaced as needed; four bolts hold the modular flap valves in place for quick maintenance and repair.

AODD pumps operate without the need for electricity, as they are powered by compressed air. The left and right diaphragms are connected by a single shaft, allowing them to move in sync.

When compressed air moves the air valve, one diaphragm is pushed toward the outer wall of the pump, forcing liquid out through the outlet. As this diaphragm moves, it pulls the opposite diaphragm, creating a cavity that draws liquid into the other side. This cycle repeats as long as the pump is supplied with compressed air.
