The recently enhanced CycleFlo pneumatic pump controller (photo) is designed to control pump speed and run time to deliver precise batching, metering and dosing of fluids at low and high pressures and flowrates. Featuring 32 batch presets and an intuitive programming interface, the CycleFlo controller ensures specific and repeatable fluid batches. Significant enhancements have been made to the controller in the area of power availability; previously, the company offered two CycleFlo units, each operating on a different input power. The new CycleFlo controller has the functionality of two units in one, operating on 100 to 240 V a.c. input power. The microprocessor-based unit can control pumps locally or in a remote location. When operating remotely, timers and pH controllers send signals to the CycleFlo controller to start and stop the pumping cycle once a preset volume of product has been dispensed — Graco Inc., Minneapolis, Minn.
