GRUNDFOS MPC E4 CR10-3 Booster systems Pump with frequency converter control. Pressure booster system supplied as compact assembly according to DIN standard 1988/T5. The pumps are CR pumps connected to an external Grundfos CUE frequency converter.
- Hydro MPC-E maintains a constant pressure through continuous adjustment of the speed of the pumps.
- The system performance is adapted to the demand through cutting in/out the required number of pumps and through parallel control of the pumps in operation.
- Pump changeover is automatic and depends on load, time and fault.

PUMP OPERATION
Dry-running protection and diaphragm tank are available according to the list of accessories. Pump operation is controlled by Control MPC with the following functions:
- Intelligent multi-pump 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.
- 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).
- 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 against malfunction.
- Alarm log with the previous 24 warnings/alarms.
- Display and indication functions:
- Colour Screen display
