AODD Pump for Chemical Transfer — Corrosion-Proof Chemical Dosing & Transfer
Chemical transfer demands a pump that will not leak, corrode or contaminate the product. AODD pumps with PTFE wetted parts handle nearly the full pH range — concentrated acids, caustics, solvents, plating baths — with zero mechanical seals to leak and no electricity at the pump head.
Application Challenges & How AODD Pumps Solve Them
The Challenges
- ✕Corrosive media attacking pump internals
- ✕Seal leakage contaminating product and plant
- ✕Hazardous area restrictions on electric motors
- ✕Dosing accuracy at low flow
- ✕Viscous and gas-entrained chemicals
The AODD Answer
- ✓Sealless air-powered design handles it — no seals to leak, no motor to spark, no impeller to clog.

FAQ — Chemical Transfer
Can an AODD pump handle concentrated sulfuric acid?
Yes — with PTFE wetted parts and PTFE diaphragms, AODD pumps handle concentrated acids including sulfuric, hydrochloric and nitric. Confirm concentration and temperature with our team for exact material selection.
Are AODD pumps safe in explosive atmospheres?
Yes. Air-powered with no electric motor at the pump, AODD pumps are inherently safe for hazardous areas — no ATEX-rated motor required.
How do I dose chemicals accurately with an AODD pump?
Use an air flow regulator and pulse dampener to control stroke rate and smooth the flow. For precise dosing, pair with a stroke counter or flowmeter feedback loop.
