Features: 

* Fitment: This cartridge mechanical seal is designed as a replacement for Grundfos OEM Part No. 96511845. Suitable for servicing Grundfos CR series vertical multistage centrifugal pumps, helping restore a reliable shaft seal between the pump shaft and casing while preventing liquid leakage and protecting the motor from contamination.

* Specific: 

• Part Number: 96511845
• Product Type: Cartridge Mechanical Shaft Seal
• Application: Vertical Multistage Pump Repair and Maintenance
• Seal Design: Cartridge Mechanical Seal (HQQV)
• Seal Type: HQQV (Silicon Carbide / Silicon Carbide / FKM)
• Shaft Size: 16mm
• Seal Face Material: Silicon Carbide / Silicon Carbide
• Elastomer Material: FKM (Viton® Equivalent)
• Metal Components: Stainless Steel
• Function: Prevents pumped liquid from leaking along the pump shaft while ensuring reliable sealing performance under high-pressure and continuous-duty operating conditions.

* Design: Engineered as a direct replacement for the original Grundfos cartridge seal. The precision-manufactured silicon carbide seal faces provide exceptional wear resistance, low friction, and excellent thermal stability, while the FKM elastomers offer superior resistance to heat, chemicals, and aggressive liquids. The cartridge design simplifies installation, minimizes alignment errors, and delivers dependable long-term sealing performance.

* Application: Suitable for maintenance and repair of commercial, industrial, and water supply systems using Grundfos CR series vertical multistage centrifugal pumps. Ideal for replacing worn, damaged, or leaking cartridge seals during scheduled servicing or complete pump overhauls to maintain pump efficiency and extend service life.

* Compatible Model: Suitable for a range of Grundfos CR series pumps using OEM Part No. 96511845, including:

• Grundfos CR10 Series Pumps
• Grundfos CR15 Series Pumps
• Grundfos CR20 Series Pumps
• Grundfos Vertical Multistage Pumps fitted with HQQV 16mm Cartridge Seals

Also suitable for equivalent pump models using cartridge seal reference 96511845. Always verify the original part number and seal specification before ordering, as some CR pump variants use different shaft sizes or seal configurations.

* Material: Manufactured using premium silicon carbide seal faces, FKM (Viton® equivalent) elastomers, and corrosion-resistant stainless steel components, providing excellent resistance to abrasion, chemicals, corrosion, and high operating temperatures for extended service life.

* Performance: Designed for long-lasting performance with:

• Effective prevention of liquid leakage
• High wear resistance under continuous operation
• Excellent chemical and corrosion resistance
• Low-friction sealing for improved pump efficiency
• Reliable performance in high-pressure applications
• Extended service life in commercial and industrial pumping systems
