Why This Product

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.

Authorized Grundfos Distributor

PumpStop supplies genuine Grundfos CR pumps with full manufacturer warranty and factory-trained technical support.

Important Notices
Electrical Verify supply voltage, phase, and frequency match nameplate before installation: 230-277D/400-480YV, 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. 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.
