Cast iron head and base, stainless steel wetted parts, with integrated variable frequency drive and IE5-rated permanent magnet motor for energy-optimized pressure control. Nominal performance: 115US gpm at 125.8ft. Rated 440-480V, 3.0-Phase, 60 Hz. Applications include HVAC: Heating, HVAC: Air Conditioning, Plumbing: Pressure Boosting and more. Power 7.5HP Voltage 440-480V Phase 3.0-Phase Max Flow 115US gpm Max Head 125.8ft Max Pressure 232.06psi Grundfos World's largest pump manufacturer — engineering and manufacturing in 17 countries since 1945 Ultra-Premium Efficiency IE5 motor — reduces operating cost over service life Authorized Distributor Genuine Grundfos product — full manufacturer warranty coverage Expert Support Technical help available — call (781) 281-8905 or chat 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.

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.
