Dosing pump ATHENA AT-AM4 (55 l/h at 2 bar)

ATHENA AT-AM4 Dosing Pump — Maximum Performance for Large Water Treatment Systems

The ATHENA AT-AM4 is the flagship model of Injecta's line of digital diaphragm dosing pumps, offering a capacity of 55 l/h for large commercial pools and industrial water treatment systems. Its built-in pH/Rx control and measurement device ensures continuous monitoring of chemical balance with automatic and manual calibration. The increased connection diameter of 8/12 mm and a pulse volume of 3.44 ml distinguish this model from the smaller AT-AM2 and AT-AM3, enabling operation with high reagent flow rates.

Control Functions

The pump supports proportional dosing mode and features a "Delayed Start Timer", which allows setting a delay for the start of dosing after the pump is activated to stabilize water chemical parameters. Additionally, it provides an output for external fault alarms, remote start/stop control, an input for a temperature sensor, and support for a flow level sensor.
