MATelec HydroWHIZ FPC-63320-J Mild Steel Three Phase 18.5 kW Variable Speed Three Pump Controller

Water transfer, stormwater and sewage with three pumps are addressed by the HydroWHIZ FPC-63320-J, offering variable-speed regulation with level, pressure and temperature operating modes. Its 18.5 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to system demand.

Control logic allows selection between level, pressure or temperature modes, with staggered pump starting reducing excessive current draw and water surge or hammer. 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 PID speed control for pressure applications and adjustable proportional and integral values.

Jacking pump control brings Pump 1 out of sleep first, activating the main pumps when demand increases. The IP44-rated powder-coated mild steel enclosure with removable gland plate and cooling fan includes a colour touchscreen HMI for local monitoring. The touchscreen provides system and individual pump status, operating modes, logged events and diagnostic functions.

Modbus RTU RS485 enables SCADA communication, and a volt-free common fault relay provides remote status indication. Protection features include high and low limits, no-flow and pump cycle protection. 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

• Configurable low-pressure and no-flow protection
• Pump anti-seize protection runs pumps periodically during low use to help prevent seizing
• Sleep Assist Boost temporarily increases pressure before sleep, allowing a longer sleep period and reducing pump cycling
• 4-20mA analogue input accepts hydrostatic level or pressure transducers
• Individual pump circuit breaker protection helps isolate a fault with an individual pump or cable
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• Circuit breaker protected low-voltage control and input circuitry
