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: 220-277D/380-480YV, 3.0-Phase, 60 Hz.
Temperature limits	Do not exceed max fluid temperature 248°F or max ambient temperature 140°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.
