Description
The Grundfos 99472695 (CRNE 1-23 Q-P-T-E-HQQE) is a Vertical Multistage Centrifugal Pump — All Stainless Variable Speed. All stainless steel construction with integrated variable frequency drive. Variable speed and full stainless for demanding chemical or food-grade applications.
Variable Speed Plus All Stainless
CRNE combines IE5 variable speed with 316 stainless steel wetted construction — the full specification for demanding chemical, food, and pharmaceutical pressure systems.
IE5 Permanent Magnet Motor
Highest efficiency class motor reduces operating cost. Especially effective in pressure systems that spend most runtime below maximum flow.
Integrated Drive — No Cabinet Required
VFD is inside the pump head. Eliminates separate drive panel, reduces installation footprint, and simplifies commissioning.
All Stainless Steel Wetted Path
Every surface in contact with the fluid is EN 1.4401 (316) stainless. Suitable for chlorinated water, mild acids, cleaning agents, and process chemicals.
iSOLUTIONS Connectivity
Supports MODBUS, PROFIBUS, BACnet, and Grundfos GO for full BMS integration and remote performance monitoring.
Cartridge Seal — No Adjustment
Factory-set cartridge seal. No field adjustment on installation. Seal variants available for water, chemical, and high-temperature service.
| Model Number | 99472695 |
| Product Series | CRNE |
| Series Description | Vertical Multistage Centrifugal Pump — All Stainless Variable Speed |
| Seal Code | HQQE |
| Seal Description | Cartridge seal — H rubber bellows, QQ SiC/SiC faces, E EPDM O-ring |
| Electrical | Verify supply voltage, phase, and frequency match nameplate before installation. |
| Temperature limits | Do not exceed max fluid temperature per nameplate. Exceeding limits damages seals and motor insulation. |
| Dry running | Do not run dry. CRNE 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. |
