Grundfos Pump MPC F Booster systems with frequency converter control. Pressure booster system supplied as compact assembly according to DIN standard 1988/T5.
The pumps are CR(I) pumps connected to one external Grundfos CUE frequency converter. The speed-controlled operation alternates between the pumps.
- Hydro MPC-F maintains a constant pressure through continuous adjustment of the speed of the pump connected to the CUE frequency converter.
- The system performance is adapted to the demand through cutting in/out the required number of CR(I) pumps and through parallel control of the pumps in operation.
- Pump changeover is automatic and depends on load, time and fault.

PUMP OPERATION
Pump operation is controlled by Control MPC with the following functions:
- Intelligent multipump controller, CU 352.
- Constant-pressure control through continuously variable adjustment of the speed of each individual pump.
- PID controller with adjustable PI parameters (Kp + Ti).
- Constant pressure at setpoint, independent of inlet pressure.
- Soft pressure build-up (To prevent water hammer during start up).
- On/off operation at low flow.
- Automatic cascade control of pumps for optimum efficiency.
- Selection of min. time between start/stop, automatic pump changeover and pump priority.
- Automatic pump test function to prevent idle pumps from seizing up.
- Possibility of standby pump allocation.
- Possibility of backup sensor (redundant primary sensor).
- Secondary sensor (Possible to switch to another sensor/setpoint).
- Multi-sensor (up to 6 sensors to influence the setpoint).
- Manual operation.
- Possibility of external setpoint influence.
- Log function.
- Setpoint ramp.
- Possibility of digital remote-control functions:
- System on/off.
- Max., min. or user-defined duty.
- Up to 6 alternative setpoints.
- Digital inputs and outputs can be configured individually.
- Pump and system monitoring functions:
- Minimum and maximum limits of current value.
- Inlet pressure.
- Motor protection.
- Sensors and cables monitored for malfunction.
- Alarm log with the previous 24 warnings/alarms.
- Display and indication functions:
- Colour screen display.
- Green indicator light for operating indications and red indicator light for fault indications
- Potential-free changeover contacts for operation and fault.
- Grundfos bus communication.
