Why This Product

All Stainless Steel Construction — No Iron in the Fluid Path

Every wetted component — impeller, shaft, chamber stacks, flanges, and casing — is in EN 1.4401 (316) stainless steel. Eliminates iron contamination for food-grade, pharmaceutical, chemical, and high-purity water applications.

Cartridge Mechanical Seal — No Adjustment Required

Pre-set cartridge seal is factory-set to correct compression — no measurement or adjustment required at installation. Reduces installation error and ensures consistent seal face load regardless of who installs it.

Chemical Compatibility — Broad Fluid Range

EN 1.4401 stainless steel and EPDM or Viton seal materials provide compatibility across a wide range of corrosive and aggressive fluids. HQQE configuration (EPDM O-rings) for acids and alkalis. HQQV (Viton O-rings) for petroleum-based and high-temperature fluids.

Combined DIN/ANSI/JIS Flanges — Global Installation Flexibility

Pump flanges are machined to accept DIN, ANSI, and JIS flange connections with the same pump body — one pump serves all three piping standards without adapters. Significant value for facilities with mixed international piping standards.

Variable Speed with CRN E-Motor (CRNE)

CRNE variant adds integrated VFD and IE5 permanent magnet motor. Variable speed pressure control without a separate drive — reduces panel space, eliminates wiring between drive and motor, and simplifies commissioning.

Grundfos ION Technology — Remote Monitoring Ready

CR, CRN, CRE, CRNE pumps with E-motor support Grundfos iSOLUTIONS connectivity for remote monitoring, fault detection, and performance data — reducing unplanned downtime in critical process and building services applications.

Important Notices
Electrical Requires correctly rated supply — 208-230YY/460YV, 3-Phase, 60 Hz. Install with correctly rated circuit protection and motor starter.
Temperature limits Do not exceed max fluid temperature 194°F or max ambient temperature 140°F. Operating outside these limits will damage seals and motor insulation.
Dry running Do not run dry. CRN 32-2-1 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 intervals. Contact PumpStop for documentation.
