Features:
-
Stall-FreeDesign
Our "posi-shift", tandem spool air distribution valve insures reliable operation in all types of low pressure and stop/start applications. Plus, fewer parts and no o-rings result in easier maintenance. -
Oil-less Operation
No metal to metal wearing surfaces. State of the art materials and precision-manufacturing techniques combine to provide the industry's original completely oil-less design. This design means: no oil misting into the environment, no unhealthy working conditions, no oil, lubricants or grease to contaminate your products. Our oil-less design results in lower operating and maintenance costs. This design has been field proven, working trouble-free since its introduction over 15 years ago. -
Externally Serviceable Air Valve
No need to disassemble the pump for routine maintenance. The air valve can be quickly and easily maintained with minimal downtime. -
Quiet Operation
Air valve design minimizes exhaust noise providing a significantly quieter work environment. -
Variety of Elastomers
AOD pumps can be assembled with the elastomer that matches your application; Neoprene, Buna-N, Nordel®, Teflon®, Santoprene® and Viton® are all available. -
Plastic Air Valve Body
Models up to 1-1/2" incorporate plastic air valve bodies for greater corrosion resistance in aggressive environments. - Note: Stainless Steel models are not sanitary rated, but may be used in certain sanitary applications.
Stall-free Performance:
- Widest performance envelope-operates on as low as 5 PSI (.35 kg/cm2) and as slow as 1 GPH (3.5 liter/hr).
- Bulk transfer applications- even dry powder can be handled efficiently.
- 100% confidence in start/stop batching applications.
- 100% confidence for "on-demand" dispensing systems.
- Viscous liquids, paint and inks are efficiently handled.
- Excellent on low flow chemical injection systems.

Minimal Maintenance:
- The externally serviceable main spool makes inspection quick and easy. All AOD models allow simple access to the main spool.
- There is never a need to take the pump out of service or to disassemble the pump to inspect the main spool.
- Utilizing the fewest air valve components of any major diaphragm pump manufacturer.
