Air Operated Double Diaphragm Pump
High-Performance AODD Pump
High-Performance AODD Pump – Reliable, Efficient, and Low Maintenance
Our AODD (Air-Operated Double Diaphragm) pumps are designed for superior efficiency with a sealless construction, ensuring low material shear and minimal maintenance.
- Run Dry Without Damage – Built for durability, capable of dry-running without wear.
- Powerful Flow & Low Pulsation – Enlarged ball valves and fluid passages provide higher flow rates, while an advanced pilot air-distribution valve minimizes pulsation and prevents stalling.
- Self-Lubricating & Maintenance-Free – Designed for long-term operation without frequent servicing.
- Dual Ceramic Dynamic Seals – Highly resistant to wear and contaminants, ensuring longevity even under fluctuating air supply conditions.
- Anti-Icing Design – Integrated energy dissipation chamber reduces air discharge pressure, prevents icing, and minimizes noise.
- High Lift & Stable Performance – Optimized air system enhances efficiency and prevents leakage.
Choose our AODD pumps for high performance, durability, and easy installation—the ideal solution for demanding applications.
