MATelec HydroWHIZ FPC-63420-D Mild Steel Three Phase 3 kW Variable Speed Four Pump Controller

Water transfer, stormwater and sewage with four pumps are managed by the HydroWHIZ FPC-63420-D, providing variable-speed regulation with level, pressure and temperature operating modes. Its 3 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to system demand.

The control module executes duty sharing, rotation and staging as demand changes, with bumpless transfer for smooth transitions. Adjustable duty sharing and alternation allow operating responsibility to be rotated between pumps. Pressure-control functions include jacking pump support, Pipe Fill and Sleep Assist Speed Minimise, with staggered start-stop delays reducing water surge.

Proportional speed control responds to level or temperature signals, while PID control handles pressure with adjustable proportional and integral values. Housed in an IP44 mild steel enclosure with thermostatically controlled fan, the panel includes a colour touchscreen HMI. The touchscreen provides system and individual pump status, operating modes, logged events and trend graphs.

Modbus RTU RS485 provides SCADA connectivity, and a volt-free common fault relay delivers remote alarm signalling. Protection features include 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

• Interactive colour touchscreen HMI displays live system status, motor speeds and logged event history
• 4-20mA analogue input accepts hydrostatic level or pressure transducers
• Padlockable mains power isolator allows the incoming power supply to be physically isolated during servicing and maintenance
• Eight digital 24Vdc inputs for backup float switches, pressure switches or thermostats
• Pipe Fill gently fills empty lines and shuts down if pressure cannot be built within 10 minutes
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• Pump anti-seize protection runs pumps periodically during low use to help prevent seizing
