DYNA 70025 Actuator (Stanadyne)

The Barber Colman Integral Governor System for Stanadyne D Series injection pumps has been designed in close cooperation with Stanadyne. Through this cooperation a uniquely simple integrated governor is now available.

Barber Colman has taken a proven rotary actuator and built it into a new cover design for Stanadyne D Series injection pumps. This new integrated approach eliminates all brackets and external linkage. No internal parts to the injection pump need to be added or replaced.

The actuator design utilizes the principle of variable reluctance. This simple design of a proportional electric solenoid has a rotating armature whose magnetic force is proportional to input coil current.

The integrated actuator and injection pump housing is very easy to install. Simply remove the existing cover and install the new cover. Along with the standard model, a completely sealed model is also available. Pollutants from contaminated fuel can cause the actuator to bind and hinder the engine governing. For those contaminated fuel applications, the completely sealed model prevents pollutants from entering the actuator and causing erratic governing.
