MATelec HydroWHIZ FPC-63320-C Mild Steel Three Phase 2.2 kW Variable Speed Three Pump Controller

Water transfer, stormwater and sewage with three pumps are managed by the HydroWHIZ FPC-63320-C, providing variable-speed regulation with level, pressure and temperature operating modes. Its 2.2 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

Duty rotation balances run hours across the three pumps, while bumpless transfer ensures smooth transitions between active drives. 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 pressurise empty pipelines, with staggered starting reducing excessive current draw and water hammer.

The IP44 mild steel enclosure with thermostatically controlled fan houses a colour touchscreen HMI for local programming and diagnostics. The touchscreen provides system and individual pump status, operating modes, logged events and trend graphs. Modbus RTU RS485 enables SCADA communication, and a common fault relay provides remote status indication.

Individual pump circuit breakers and a padlockable mains isolator are fitted as standard equipment. 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

• Dedicated pump circuit breakers ensure physical electrical isolation for each individual drive
• Circuit breaker protected low-voltage control and input circuitry
• Pump anti-seize protection runs pumps periodically during low use to help prevent seizing
• Volt-free common fault contact for building automation feedback
• Pipe Fill gently builds pipe pressure during startup
• Padlockable mains power isolator switch allows the incoming power supply to be physically isolated during servicing and maintenance
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
