A2 Features
Features and Benefits
Accu-Flo™ Series Air-Operated Double-Diaphragm (AODD) Pumps give you the critical external pump control necessary for exacting applications such as batching. Featuring a direct electrical interface that utilizes electrical impulses to stroke the pump instead of differential pressure, the Accu-Flo Series provides a variable stroke rate that you can easily control as needed. To meet your applications, Accu-Flo Series pumps are available as NEMA 5-compliant and comes in a variety of voltage options.
- Integrated electronic (solenoid) control
- Multiple signal input voltage options: 24V DC, 12V DC and 110V AC
- Proven, robust clamped construction
