Description
The Grundfos 97669037 (CR 32-10 H-GB-A-V-HQQV) is a Inline multi stage pumps — Horizontal multistage end-suction pumps. Nominal performance: 136US gpm at 709.4ft.
Why This Product
End-Suction Close-Coupled Design
Close-coupled end-suction design eliminates the flexible coupling, coupling guard, and separate bearing housing of frame-mounted designs — fewer components, smaller footprint, and lower maintenance requirements.
Back Pull-Out Serviceability
The rotating assembly (impeller, seal, and shaft) can be removed from the back of the pump without disturbing suction or discharge piping — significantly reducing labor time and cost for installed pumps.
Wide Performance Range from One Pump Family
Available in a wide range of impeller sizes and motor HP configurations — all sharing the same volute casing dimensions and piping connections. Hydraulic performance can be adjusted without changing the pump casing or re-piping.
Cast Iron and Stainless Options
Available in cast iron for standard water and HVAC applications, and stainless steel or bronze for corrosive and food-grade service. Select the material matched to your specific fluid chemistry.
Grundfos iSOLUTIONS Compatible
NBS-E and TP-E variants support Grundfos iSOLUTIONS monitoring and control — remote performance data, fault detection, and variable speed control via Grundfos GO or building management system integration.
Global Service Support

| Temperature limits | Do not exceed max fluid temperature 194°F. Operating outside these limits will damage seals and motor insulation. |
| Dry running | Do not run dry. CR 32-10 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. |
