Why This Product

Integrated Variable Frequency Drive

The VFD is built into the pump head — no external drive cabinet, no panel wiring, no drive-to-motor cable. Reduces panel space, installation cost, and failure points.

IE5 Permanent Magnet Motor

CRE uses a Grundfos MGE permanent magnet motor rated IE5 — the highest commercially available efficiency class. Significant energy reduction vs IE3 motors at partial load.

Proportional Pressure Control

AUTOADAPT automatically adjusts set point based on actual system demand. No manual curve adjustment needed after commissioning.

iSOLUTIONS Ready

CRE supports Grundfos GO app, CIM communication modules (PROFIBUS, MODBUS, BACnet), and remote monitoring. Full integration into building management systems.

Soft Start Built In

The integrated drive provides controlled ramp-up, eliminating water hammer and reducing mechanical stress on seals and couplings at every start.

Pump Protection Built In

Dry-run protection, over-temperature shutdown, and motor current monitoring are standard in every CRE. No external protection relay required.

Important Notices
Electrical Verify supply voltage, phase, and frequency match nameplate before installation: 380-500V, 3.0-Phase, 50, 60 Hz.
Temperature limits Do not exceed max fluid temperature 248°F or max ambient temperature 122°F. Exceeding limits damages seals and motor insulation.
Dry running Do not run dry. CRE pumps use the pumped fluid to lubricate the shaft seal. Dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance. Contact PumpStop for documentation.
