Neptune Metering Pumps - Electronic Stroke Control

The Neptune Electric Stroke Control allows the capacity of any Neptune Series 500 or Series 600 " dia-PUMP" to be automatically controlled in response to a standard 4-20 mA process signal. Also accepts 0-5 VDC/ 0-10 VDC signal or digital pulse train inputs. One-piece controller- positioner mounts directly to the pump. No machining or any special drillings or tappings needed to retrofit pump. Ideal for water/ wastewater, power and process industry applications...anywhere that pump flow must be automatically proportioned or varied. Features and Benefits • Stroke position indicator on controller. ( Also on optional remote control module.) Permits fast, easy visual check of pump stroke length. • Remote control unit ( optional) . Allows manual override and monitoring from remote location. • Switch reversible. Allows direct or indirect response to signal. • Separate signal and power entrance connections to terminal blocks. • Adjustable ratio. Great control flexibility. • Signal interruption " memory." If process signal is lost, unit can remain in its last position or move to a preset position. • Adjustable travel time: 15 seconds minimum • Input signal optically isolated from the line voltage. Eliminates inexact positioning which could be caused by extraneous electrical interference. • Alarm function relay monitors: 1) movement to max/ min preset limits; 2) movement to adjustable upper/ lower limits. Gives early warning to malfunctions or process upsets, allows for quick corrective actions. Electronic, Stroke, Control, Metering, Pumps, Neptune, Chemical, Pump, Comp any, Inc
