Description
The Grundfos 96523586 (CRN15-04 A-P-G-E-HQQE) is a Vertical Multistage Centrifugal Pump — All Stainless, 1-Phase. All wetted components in EN 1.4401 (316) stainless steel. For corrosive, aggressive, and high-purity fluids where cast iron components are unsuitable. Grundfos Pumps CRN15-04 A-P-G-E-HQQE 1x 208-230 60 Hz Vertical Multistage Centrifugal Pump Model 96523586, 2" x 2", 7 1/2 HP, 1 Phase
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.
| Model Number | 96523586 |
| Product Series | Vertical Multistage Centrifugal Pump — All Stainless |
| Model Code | CRN15-04 A-P-G-E-HQQE |
| Phase | 1-Phase |
| Frequency | 60 Hz |
| Motor Type | ECM permanent magnet (IE5) |
| Shaft Seal | Cartridge seal — rubber bellows / SiC-SiC faces / EPDM O-rings |
| Pipe Connection | P |
| Orientation | Vertical |
| Electrical | Requires correctly rated supply — 1-Phase, 60 Hz. Install with correctly rated circuit protection and motor starter. |
| Temperature limits | Do not exceed max fluid temperature (see spec sheet) or max ambient temperature (see spec sheet). Operating outside limits damages seals and motor insulation. |
| Dry running | Do not run dry. Grundfos CR/CRN/MTR 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, maintenance intervals, and spare part numbers. Manuals available from Grundfos or PumpStop. |
