Why This Product
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.

Important Notices
| Electrical | Verify supply voltage, phase, and frequency match nameplate before installation: 440-480V, 3-Phase, 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. 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. |
