The pump capacity of hydraulic diaphragm metering pumps can be controlled both manually and automatically. Automatic adjustment can be handled by an Electronic Capacity Control (ECCA). This replaces the standard manual micrometer knob and can be mounted directly onto the pump. AquFlow’s ECCA uses miniaturized, state-of-the-art electronic technology built around an AC synchronous motor, which permits precise actuator travel, without hunting or overshoot.
The actuator may be housed in a NEMA 4X enclosure or NEMA 7 enclosure. Regardless of choice of enclosure, the ECCA is designed with convenient installation and maintenance in mind. Color-coded wiring leads simplify field installation and are fully encapsulated to keep moisture out. Encapsulated wiring leads also eliminate the need to open actuator housing to accomplish field wiring.
