General Description
The CycleFlo is a pneumatic pump controller that allows precise control over the amount of product that is
delivered by the pump as well as the pump speed. The CycleFlo achieves this by operating the pump for a preset
number of cycles and then halting the pumping cycle. Up to 32 different batch sizes may be programmed into the
memory of the CycleFlo for easy delivery of different product volumes.
A batch may be initiated either from the front panel RUN button or via a remote switch. Such a remote switch may
be connected to the trigger of a dispensing valve so that the pump only pumps when the operator depresses the
valve trigger. Using the remote input, the pumping cycle may also be initiated by some other piece of equipment
such as a timer or a pH controller. The CycleFlo will halt the pumping cycle once the preset volume of product has
been dispensed.
The CycleFlo also features an adjustable pumping rate. This allows the CycleFlo to be used with different pump
types and to tailor the pump cycle to deliver fluids with a variety of flow characteristics.
Installation
Pneumatic Connections
The integrated air valves (solenoids #1 and #2), located on the right side of the CycleFlo enclosure, have a
common air inlet (1/4"NPT) port at the bottom and two outlet ports (1/8"NPT to ¼" elbow tube fitting) towards the
front of the unit. The exhaust is silenced with a muffler.

The "A" and "B" outlet ports are to be connected to the "A" and "B" ports respectively on the Husky 205, or to the
two air valve control ports located on the air motors of pumps larger than the Husky 205. The unit comes
equipped with ¼" OD push-in tube fittings installed in the "A" and "B" ports.
On pumps larger than the Husky 205, a three way solenoid valve (Graco Part Number 115605 or equivalent)
should be installed on the main air supply to the pump. This ensures that pressure is not generated by the pump
when the controller is not operating. The Air Supply Valve Signal output on the CycleFlo Controller is designed to
control this valve.
