Description
The Grundfos 99469020 (CRE 20-2 IN-GJ-A-E-HQQE) is a Vertical Multistage Centrifugal Pump — Variable Speed. 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: 111US gpm at 104ft.
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.

| Electrical | Verify supply voltage, phase, and frequency match nameplate before installation. |
| Temperature limits | Do not exceed max fluid temperature 248°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. |
