Why This Product
All Stainless Steel Construction
Every wetted component — impeller, chambers, shaft, head — is stainless steel EN 1.4401 (316). No iron contact with the pumped fluid under any condition.
Corrosion-Resistant for Aggressive Fluids
316 stainless resists chlorides, mild acids, and alkaline cleaning agents. CRN is the preferred selection for food processing, pharmaceutical, and chemical dosing systems.
Cartridge Mechanical Seal
Factory-set cartridge seal eliminates field adjustment on installation. Seal options cover standard water through aggressive chemical service.
Dual Flange Standard — DIN, ANSI, JIS
CRN ships with combined DIN/ANSI/JIS flange connections. One pump fits piping standards across North American and international installations.
3-A and FDA-Compliant Options
Selected CRN configurations are 3-A certified for dairy and food processing. FDA-compliant elastomers available on request.
Wide Pressure Range
CRN series covers up to 60 bar operating pressure across pump sizes. Confirm your system maximum working pressure before selecting.

Important Notices
| Electrical | Verify supply voltage, phase, and frequency match nameplate before installation: 230/460V, 3.0-Phase, 60 Hz. |
| Temperature limits | Do not exceed max fluid temperature 194°F or max ambient temperature 104°F. Exceeding limits damages seals and motor insulation. |
| Dry running | Do not run dry. CRN 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. |
