Grundfos Hydro MPC-E 4 CRIE3-2 98426892 IE5 230v

Pressure booster system supplied as compact assembly according to DIN standard 1988/T5.

All pumps are speed-controlled.

From 0.37 to 11 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 applies to IE5 level in IEC60034-31.

From 15 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:

Pump parts in contact with the pumped liquid are made of stainless steel EN DIN 1.4301 Pump bases and heads are of either 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.
