Grundfos CR 5-10 Vertical Multistage Centrifugal Pump
Engineered for industrial fluid transfer, water supply, and high-pressure washing applications, the Grundfos CR 5-10 is a premium vertical multistage centrifugal pump designed to deliver uncompromising hydraulic efficiency and space-saving vertical reliability. Built with a robust, cast iron base and motor stool paired with high-grade stainless steel internal impellers and chambers, this pump excels at continuous duty cycles in demanding mechanical systems.
The CR 5-10 features Grundfos’s signature cartridge shaft seal design, which significantly increases uptime by allowing seal replacements to be executed in minutes without removing the motor. Its balanced mechanical seal layout withstands severe thermal shifts and high system operational pressures, providing optimal leakage protection and long service lives.
Key System Performance Baselines:
- Multistage Hydraulic Stack: 10-stage impeller configuration yields high head pressures while maintaining a highly compact vertical footprint.
- Heavy-Duty Mechanical Build: Cast iron outer housing protects precision-machined laser-welded stainless steel hydraulic components to maximize wear resistance.
- Advanced Cartridge Seal: Silicon carbide/silicon carbide mechanical seal faces with EPDM elastomers ensure excellent chemical and thermal endurance.
- Flange Configuration: Features standard inline oval or round flange connections to simplify direct piping integration.
⚠️ Application Profile: This CR series configuration is highly optimized for water treatment systems, boiler feed loops, process water pressure boosting, and municipal secondary distribution circuits.
