Grundfos 00506174 Cartridge Kit
The Grundfos 00506174 Cartridge Kit is a critical OEM replacement part designed for Grundfos UP15 series pumps, including the popular UP15-42F and UP15-42SF models. For contractors maintaining hydronic heating or hot water recirculation systems, this kit provides a direct solution for restoring head pressure and flow rates. By replacing the internal rotating assembly—rather than the entire pump housing—technicians can significantly reduce downtime and labor costs during circulator pump repair. This genuine Grundfos replacement cartridge is manufactured to factory tolerances, ensuring optimal water circulation and system efficiency while eliminating the noise and vibration associated with worn bearings or calcified impellers.
Key Benefits for Technicians
- Direct Compatibility: Engineered specifically for Grundfos UP15 pumps to ensure a precise mechanical fit and matched hydraulic performance.
- Operational Restoration: Replaces worn internal components to eliminate motor humming, shaft seizing, and reduced flow issues.
- Industrial Build Quality: Utilizes high-grade materials resistant to the thermal stresses of continuous domestic water circulation.
- Cost-Effective Maintenance: Avoids the need for full pump removal and plumbing reconfiguration by utilizing the existing volute.
- Energy Efficiency: Restores the pump's original electrical draw profile and flow curve, preventing wasted energy in HVAC hydronic systems.
Common Questions
Is this kit compatible with the UP15-10BUC5/LC series?
Yes, the 00506174 is the standard cartridge kit for the majority of the UP15 fixed-speed series. Always verify the specific model number on the pump nameplate before installation.
What is included in the Grundfos 00506174 kit?
The kit contains the complete internal cartridge assembly, including the impeller, rotor, and necessary gaskets required to reseal the pump head to the housing.
Why should I use an OEM kit over an aftermarket alternative?
Genuine Grundfos replacement parts maintain the UL/CSA listings of the pump and ensure that the performance curves remain consistent with the original system design, preventing imbalances in zoned heating loops.
