Grundfos 96746905 Chamber Stack Kit
The Grundfos 96746905 Chamber Stack Kit is a critical pump repair assembly engineered for the maintenance and overhaul of vertical multistage centrifugal pumps, specifically the CRI 5-18 and CR 5-18 series. As a veteran-grade OEM replacement part, this kit contains the full internal sequence of impellers, chambers with integral neck rings, and bearing rings required to restore original hydraulic performance. When handling multistage pump kits, ensuring proper pump stage alignment is paramount to prevent internal friction and premature wear. This stack kit is designed for the Grundfos 5-stage architecture, providing a precise CRI series pump fit that mitigates NPSH issues and maintains peak efficiency in high-pressure water transfer and industrial applications. Replacing the entire chamber stack ensures that all rotating and stationary components wear evenly, eliminating the common performance drop-offs seen with piecemeal pump parts replacement. This heavy-duty Grundfos 96746905 assembly is built to withstand rigorous operation in commercial HVAC systems, boiler feed units, and pressure boosting stations.
- System Restoration: Provides all necessary impellers and chambers to return the CRI 5-18 to factory flow and pressure specs.
- Mechanical Integrity: Includes high-grade neck rings and bearings to ensure stability throughout the vertical shaft assembly.
- Efficiency Gain: Reduces energy consumption by eliminating internal bypass and recirculating losses caused by worn pump stages.
- Application Versatility: Ideal for potable water, industrial cooling, and HVAC circulation where CRI pumps are standard.
Common Questions
Is this kit compatible with standard CR series pumps?
Yes, the Grundfos 96746905 is designed for use in both CR 5-18 and CRI 5-18 models, as they share the same internal hydraulic stack kit geometry.
Does the kit include the shaft seal or O-rings?
This is a complete chamber stack assembly. While it includes the internal chambers and impellers, external shaft seals and sleeve O-rings are typically sourced separately during a full pump rebuild.
How do I ensure the stack is aligned correctly during installation?
Technicians must align the straps with the centerline of the pump inlet and outlet and verify the neck ring seating to prevent pump vibration or mechanical seizing.
