Description
The Grundfos 99968325 (CR 32-5-2 K-G-A-E-HQQE) is a Vertical Multistage Centrifugal Pump. Cast iron head and base, stainless steel wetted parts. Used in water supply, pressure boosting, HVAC, and industrial liquid transfer. Nominal performance: 159US gpm at 325.1ft. Rated 230/460V, 3.0-Phase, 60 Hz. Applications include HVAC: Heating, HVAC: Air Conditioning, Plumbing: Pressure Boosting and more.
Vertical Multistage Design
Multiple stages in series deliver high head at compact footprint. CR handles up to 60 bar and flow ranges from 0.5 to 900 m³/h across the series range.
Stainless Steel Wetted Parts
All parts in contact with the pumped fluid are stainless steel — impeller, shaft, chamber. Cast iron is used only for the head and base which never contact the fluid.
QuickTight Connection System
No special tools needed for coupling. Integrated coupling design reduces installation and service time.
Wide Configuration Range
Available in 60+ frame sizes and 16 impeller variants. CR can be configured for almost any pressure/flow combination in commercial and industrial water systems.

| 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 248°F or max ambient temperature 104°F. Exceeding limits damages seals and motor insulation. |
| Dry running | Do not run dry. CR 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. |
