MATelec HydroWHIZ FPC-63320-G Mild Steel Three Phase 7.5 kW Variable Speed Three Pump Controller

Water transfer, stormwater and sewage with three pumps benefit from the HydroWHIZ FPC-63320-G, which delivers variable-speed regulation with level, pressure and temperature operating modes. Its 7.5 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

Coordinating pump control, the controller provides automatic duty alternation and bumpless transfer to rotate duty pumps and stagger startup cycles. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup, with staggered start-stop delays reducing water surge.

Proportional speed control handles level and temperature regulation, while PID control responds to pressure changes. Housed in an IP44 mild steel cabinet with integral cooling fan and removable gland plate, the panel includes a colour touchscreen HMI for local monitoring. The touchscreen provides system and individual pump status, operating modes, logged information and diagnostic functions.

Modbus RTU RS485 provides SCADA connectivity, and a volt-free common fault relay delivers remote alarm signalling. Configurable protection covers high and low limits, no-flow and feedback-signal faults. VSD and system protection functions monitor operating conditions and provide configurable responses to faults such as overload, pressure, level, temperature, no-flow and feedback-signal conditions.

Features
