Grundfos 96508459 Stack Kit
When you are dealing with a drop in pressure or a loss of efficiency on a Grundfos CR15-7, the Grundfos 96508459 Stack Kit is the professional choice for a complete internal rebuild. This genuine OEM replacement chamber stack kit is engineered specifically for vertical multistage centrifugal pumps, containing the impellers and chambers required to restore factory-spec flow and head pressure. Rather than piecemealing individual components, this kit allows contractors to perform a comprehensive overhaul, addressing wear across the entire rotating assembly and stationary stages to ensure long-term reliability in high-demand industrial fluid transfer and commercial pressure boosting applications.
Precision-balanced to mitigate vibration and premature mechanical seal fatigue, the 96508459 chamber stack kit maintains tight tolerances necessary for water supply systems and process cooling. With a net weight of 17.6 lbs and a shipping volume of 38.118 cdm³, this Grundfos pump repair kit is built from robust materials designed to handle the hydraulic stresses of the CR15 series. Using OEM Grundfos pump parts ensures that the stack geometry matches the original hydraulic profile, preventing the cavitation and energy loss common with aftermarket alternatives.
Key Benefits for Technicians:- Direct Compatibility: Engineered specifically for the Grundfos CR15-7, ensuring a perfect seat within the pump sleeve.
- Restored Efficiency: Replaces worn impellers and chambers to return the pump to its original performance curve.
- Reduced Downtime: A pre-assembled stack allows for faster field service compared to individual component replacement.
- OEM Quality: Genuine Grundfos internals provide superior metallurgical properties for better wear resistance.
- Hydraulic Balance: Factory-aligned components minimize shaft runout and extend the life of the motor bearings.
Is the 96508459 kit compatible with other CR15 stages?
No, this specific stack kit is configured only for the 7-stage CR15-7. Using it in pumps with more or fewer stages will result in incorrect hydraulic performance and potential motor overload.
Does this kit include the mechanical shaft seal?
Typically, the stack kit focuses on the chambers and impellers. It is industry-best practice to purchase a separate HQQE or HQQU shaft seal kit when installing a new chamber stack to ensure a complete leak-free rebuild.
How do I know if my CR15-7 needs a new stack?
If the pump is running but unable to hit the design setpoint, or if you notice an increase in amp draw alongside a decrease in discharge pressure, the internal impellers or chambers are likely eroded or bypass-damaged.
