Controller offers flexibility for water supply systems

摘要

Andritz's newly developed pump controller (APC) is a flexible and individual control unit for interconnected pumps in sprinkler, wastewater, lifting, pressure boosting and fire extinguishing systems and also in water supply networks. In the standard design, the APC provides functions like display, operation, notification and control in accordance with the pre-defined control variables (pressure, head and flow rate) for up to six pumps. The control system switches the pumps on and off, replaces them for optimum distribution of use, changes pumps over in the event of a fault and provides protection functions such as dry running protection, flow monitoring and anti-jamming. All these functions are performed automatically.
