Engineered for precision repair and preventive maintenance, the Grundfos 96455086 (Model HQQE / KB012S1) is a genuine OEM 12mm cartridge mechanical shaft seal kit designed for Grundfos CR, CRI, and CRN 1S, 1, 3, and 5 series vertical multistage centrifugal pumps. Rated for operating pressures up to 30 bar (435 PSI), this cartridge-style seal restores factory hydraulic sealing and prevents fluid leakage in high-pressure commercial and industrial pumping systems.
The 96455086 seal kit features Grundfos’s advanced HQQE material arrangement, combining hard-wearing Silicon Carbide / Silicon Carbide (QQ) primary seal faces with chemically resistant EPDM (E) elastomers housed in a balanced 12mm cartridge assembly (H). Engineered to withstand high-temperature fluid cycles, abrasive particulate exposure, and continuous duty, this pre-assembled unit drops directly into place during routine service without requiring full pump teardowns.
Key System Performance Baselines:
- Genuine OEM Replacement: Manufactured to exact Grundfos factory tolerances for CR 1S, CR 1, CR 3, and CR 5 series vertical pumps.
- HQQE Material Configuration: Silicon Carbide vs. Silicon Carbide seal faces paired with durable EPDM rubber O-rings.
- 30 Bar Pressure Rating: Engineered to handle high-pressure booster systems and boiler feeds up to 435 PSI (30 bar).
- Pre-Assembled Cartridge Design: Allows fast, error-free field replacement to minimize system downtime.
⚠️ Application Profile: Compatible with Grundfos CR 1S/1/3/5, CRI 1S/1/3/5, and CRN 1S/1/3/5 vertical multistage pumps used in commercial pressure boosting, boiler feed loops, water treatment, and industrial fluid transfer requiring a 12mm shaft seal.
