Grundfos 00985204 Seal Kit
The Grundfos 00985204 Seal Kit is a field-critical repair solution designed specifically for Grundfos CR16 and CRN16 vertical multistage pumps. As a standard HQQE shaft seal, this kit features silicon carbide/silicon carbide seal faces and EPDM O-rings, providing superior chemical resistance and thermal stability for water-based applications. Engineered for the balanced cartridge seal design common in the CR series, it ensures precise pump axial alignment and eliminates the leakage issues frequently encountered during high-pressure cycles. This mechanical seal replacement is vital for maintaining the hydraulic integrity of the assembly, preventing cavitation and premature motor bearing failure. For contractors managing HVAC secondary pumping systems or industrial process loops, utilizing this genuine OEM Grundfos pump part is the only way to ensure the 12mm or 16mm shaft diameter tolerances are met without compromising the NPSH requirements of the system.
Key Benefits for Technicians- Material Composition: Silicon carbide (SiC/SiC) primary and secondary rings provide extreme hardness for abrasive fluid handling.
- EPDM Secondary Seals: Optimized for glycol-water mixtures and high-temperature service up to 248°F.
- Cartridge Design: Simplifies field installation, reducing the risk of face contamination or incorrect spring tensioning.
- System Reliability: Restores factory-spec sealing to prevent costly downtime in critical commercial booster sets.
Is the 00985204 seal kit compatible with CRN series pumps?
Yes, this HQQE seal is designed for both CR and CRN 16 models, provided the shaft size and material compatibility with the pumped medium (typically water or light chemicals) are matched.
Does this kit include the O-rings for the pump chamber?
The 00985204 kit specifically focuses on the mechanical shaft seal assembly and its internal secondary seals; however, it is standard practice to inspect the outer sleeve O-rings simultaneously during tear-down.
What is the temperature range for the HQQE seal type?
The EPDM components in this kit are rated for fluid temperatures ranging from -22°F to +248°F, making it suitable for most hydronic heating and cooling applications.
