Grundfos Zestaw podnoszenia ciśnienia Hydro MPC-E 2 CRE 20-6 99209324
- Zestawy podnoszenia ciśnienia z silnikami MGE
Booster system supplied as compact assembly according to DIN standard 1988/T5.
All pumps are speed-controlled.
From 0.37 to 2.2 kW, the booster system is equipped with CR, CRE, CRI, CRIE pumps with electronically commutated permanent-magnet motors with extremely high efficiency.
The total efficiency of the motor including the frequency converter is better than the IE4 level in IEC60034-31, even though this standard only applies to the motor.
From 3 to 22 kW, the booster system is equipped with CR, CRE, CRI, CRIE pumps with motors with integrated frequency control. The total efficiency of the motor including the frequency converter is better than the IE3 level in IEC60034-31, even though this standard only applies to the motor.
- 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.

The system consists of these parts:
:vertical, multistage centrifugal pumps, type CRE 20-6
Pump parts in contact with the pumped liquid are made of stainless steel EN DIN 1.4301
Pump bases and heads are of cast iron/stainless steel (CRI) or cast iron EN-GJS-500-7 (CR), depending on pump type; other vital parts are made of stainless steel EN DIN 1.4301
The pumps are equipped with a service-friendly cartridge shaft seal, HQQE (SiC/SiC/EPDM)
- Two stainless steel manifolds to EN DIN 1.4571
- Stainless steel base frame to EN DIN 1.4301 up to CR 90; above CR 90 the pumps are placed on a galvanized I-Beam frame
- One non-return valve (POM) and two isolating valves for each pump
- Non-return valves are certified according to DVGW, isolating valves according to DIN and DVGW
- Adapter with isolating valve for connection of diaphragm tank
- Pressure gauge and pressure transmitter (analog output 4-20 mA)
- Control MPC in a steel cabinet, IP54, including main switch, all required fuses, motor protection, switching equipment and microprocessor-controlled CU 352.

Dry-running protection and diaphragm tank are supplied as a essensial part of the system.
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.
- 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 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.
