AODD Pump for Wastewater — Sludge Transfer, Dosing & Sump Duty
Wastewater treatment is relentless — sludge, grit, chemicals and continuous duty. AODD pumps handle it all: thick sludge with solids, polymer dosing, lime slurry and sump transfer. Self-priming and run-dry-safe, they survive the abuse that kills centrifugal pumps.
Application Challenges & How AODD Pumps Solve Them
The Challenges
- ✕Abrasive sludge eroding pump internals
- ✕Solids clogging impellers and seals
- ✕Dosing polymer and chemicals accurately
- ✕Intermittent operation with dry running
- ✕Corrosion from aggressive treatment chemicals
The AODD Answer
- ✓Sealless air-powered design handles it — no seals to leak, no motor to spark, no impeller to clog.

FAQ — Water & Wastewater
Can an AODD pump handle sludge with solids?
Yes — 2" and 3" AODD pumps pass solids up to 9.5 mm (3/8") through large ball-check passages, making them ideal for primary sludge and grit-laden media.
Can AODD pumps run dry in sump duty?
Yes — AODD pumps run dry indefinitely without damage, ideal for automatic sump emptying where the supply can run out between cycles.
Are AODD pumps good for polymer dosing?
Yes — low shear keeps polymer chains intact (high shear degrades flocculant effectiveness), and stroke-rate control gives accurate dosing.
