Grundfos 96455086 Shaft Seal Kit
The Grundfos 96455086 Shaft Seal Kit is a professional-grade cartridge seal assembly specifically precision-engineered for the Grundfos CR, CRI, and CRN pump series, covering sizes 1s, 1, 3, and 5. Labeled as an HQQE type seal, this kit features silicon carbide (SiC) primary and secondary seal faces, paired with high-performance EPDM elastomers. This material configuration is the industry standard for handling aqueous solutions and treated water within a temperature range of -4°F to +248°F (-20°C to +120°C). Designed for multistage centrifugal pumps, the balanced cartridge design facilitates a safer, more reliable replacement process compared to component seals, effectively protecting the shaft from dynamic O-ring wear. With a maximum operating pressure of 30 bar (435 psi), this mechanical seal maintains architectural integrity under demanding hydraulic conditions. For field technicians, this kit ensures a 12mm shaft fitment, providing a direct OEM-spec solution for pump shaft sealing and long-term leak prevention.
Key Benefits of the Grundfos 96455086 Kit
- Ensures high-pressure reliability up to 30 bar, preventing catastrophic leakage in vertical multistage pumps.
- Utilizes rugged silicon carbide faces to withstand abrasive particulates and maintain seal face flatnesses.
- Includes EPDM O-rings for superior resistance to hot water and chemical treatments commonly found in HVAC and booster systems.
- Features a balanced cartridge design that simplifies installation and protects the pump shaft from frictional degradation.
- Broadly compatible with Grundfos CR1, CR3, and CR5 series, including the N and I stainless steel variations.
Common Questions
What is the difference between HQQE and HQQV seals?
While both utilize silicon carbide faces (HQQ), the 96455086 HQQE seal uses EPDM elastomers, which are ideal for hot water applications. HQQV seals use FKM (Viton), which is typically selected for oil-based liquids or specialized chemical compatibility where EPDM is unsuitable.
Can I use this 96455086 kit in a 60Hz pump?
Yes, this seal is designed for the Grundfos CR series mechanical assembly and is compatible with both 50Hz and 60Hz motor configurations, provided the pump model (CR/I/N 1s, 1, 3, 5) and shaft size (12mm) match.
Does this seal require lubrication during installation?
Yes, it is standard practice to use a 5% soapy water solution or a silicone-based lubricant on the secondary O-rings and shaft to prevent rolling or tearing during the initial seating of the cartridge.
