General Description The CycleFlo II is a pneumatic pump controller that allows precise control over the cycle rate of the pump and therefor the flow rate. The pump cycle is initiated by a 120 volt signal. The pump cycle may be initiated by some other piece of equipment such as a timer or a pH controller. An isolation relay may be required in some installations. Always follow local and applicable electrical codes. The CycleFlo II will halt the pump cycle whenever the 120 volt signal is removed.

The integrated air valves, have a common air inlet (1/4" NPT) port and two outlet ports A and B (1/4” Tube) toward the front of the unit. The exhaust is silenced with a muffler. Do not exceed 120 psi at the air inlet to the unit. Refer to your pump owner’s manual for the maximum air pressure limit of the pump.
Setup & Adjustment Cycles Per Minute (CPM) Rate The pump cycle rate is adjustable to accommodate different pump sizes, varying product viscosities and product delivery speed. The pump cycle rate is measured in Cycles Per Minute (CPM), i.e. the number of times the pump performs a pump cycle in one minute. One pump cycle consists of a momentary pressurization of each one of the two diaphragms.
Operation Priming the Pump Prime the pump by applying a 120 Volt signal to the controller to allow the temporary operation of the pump. This cycle rate may be increased or decreased to facilitate pump priming. Shut off electrical supply before making adjustments. Operation Procedures The controller and pump are now ready for operation. The pump will cycle at the preset rate any time a 120 Volt signal is supplied to the controller.
