Description
3-Phase Iron Duplex Intelligent Pump Controller
The three-phase intelligent pump controller designed for
medium to large industrial and commercial dual-pump systems. Built with
powder-coated cold-rolled steel housing, it offers high durability and
reliable operation in demanding environments.
The controller supports multiple control logics including pump alternation,
duty/standby operation, synchronous dual-pump start, and cyclic timing,
ensuring efficient pump management for applications such as sewage pumping,
industrial heating circulation, water supply, and fire protection systems.
