Intelligent pump controller for wastewater operations

Jon Lawson

Sulzer’s EC 531 is an all-in-one unit for control and monitoring stations with one or two pumps. It offers control and monitoring via floats or advanced control via a continuous level signal. It is also equipped with smart VFD control including PID and BEP.

The new controller gives instant access to alarms, pump status, level information and trends. It offers functionalities to help monitor the equipment condition as well as to optimise and reduce the risk of overflow, cut down energy costs, etc.

It has variable stop/start levels and pump-down to reduce the need of sump cleaning, built-in efficiency monitoring with performance drop-off/maintenance required alert and a crash log for fault finding.
