Grundfos 96525490 Shaft Seal Kit
The Grundfos 96525490 Shaft Seal Kit is a critical HQQV mechanical seal replacement designed for the high-demand Grundfos CR series pumps. This 22mm cartridge seal features a robust silicon carbide (SiC/SiC) face construction paired with durable Viton (FKM) elastomers, making it ideal for handling aggressive fluids and high-temperature applications up to 120°C. Engineered as a balanced cartridge unit, this kit ensures a leak-proof pump maintenance solution that minimizes downtime by allowing for rapid, precise installation without the need for specialized shaft adjustment tools. Whether you are servicing a CRN 32, CRN 45, CRN 64, or CRN 90, this OEM-spec pump rebuild kit provides the torque transmission and pressure resistance required for vertical multistage centrifugal pumps in industrial water treatment or cooling systems. By replacing a leaking shaft seal with this genuine Grundfos service part, contractors can restore system hydraulic efficiency and protect the motor from moisture ingress.
Key Benefits:- HQQV Seal Configuration: Utilizes silicon carbide faces and Viton O-rings for superior chemical resistance and thermal stability.
- Cartridge Design: This 22mm balanced seal arrives as a pre-assembled unit, ensuring correct spring tension and face alignment during installation.
- Wide Compatibility: Specifically engineered for Grundfos CR/N 32, 45, 64, 90, 120, and 150 series pumps.
- High-Pressure Reliability: The balanced design reduces face load at high pressures, extending the life of the mechanical seal in continuous-duty cycles.
- Leak Prevention: Precision-ground seal faces eliminate bypass leakage, maintaining the integrity of the centrifugal pump system.
What is the difference between HQQE and HQQV seals?
The primary difference is the elastomer material. While both use silicon carbide faces, the HQQV (96525490) uses Viton (FKM) for oil and chemical resistance, whereas HQQE uses EPDM for water-based applications.
Does this kit include the grinding device for the pump shaft?
Yes, this specific Grundfos shaft seal kit is the version that includes the necessary adjustment fork and grinding device to ensure the shaft surface is prepped for a perfect seal seat.
Can I use this seal for a CRN 32 pump with a 50HP motor?
Yes, this 22mm shaft seal is compatible with CR and CRN models 32 through 150, provided the pump shaft diameter is 22mm (typically found on units up to 60 HP).
