Lochinvar & A.O. Smith 100275607 Pump Assembly
As a seasoned technician, you know that consistent circulation is the backbone of any hydronic system. The Lochinvar & A.O. Smith 100275607 Pump Assembly is a critical OEM replacement part designed for high-efficiency condensing boilers and commercial water heaters. This assembly is the primary driver for moving heated water through the heat exchanger, ensuring uniform thermal distribution and preventing localized overheating that can lead to E06 error codes or system lockouts. Engineered to meet precise flow rate requirements, the 100275607 is compatible with a wide range of Lochinvar models including the NKC110, NKC150, and NKC199 series. The inclusion of a high-temp gasket ensures a leak-free seal, maintaining the hydraulic integrity of the closed-loop system even under fluctuating pressures. Replacing a failing circulator with this genuine 100275607 pump restores heat exchanger efficiency and protects internal components from premature wear caused by poor flow dynamics or stagnant water conditions in the primary loop.
Key Benefits- Optimized Flow Dynamics: Specifically calibrated to maintain the required GPM for Lochinvar NKC and NKB boiler models, ensuring proper heat transfer across the exchanger.
- Full Assembly Integration: Ships with the necessary replacement gasket to provide a secure, airtight seal against the pump housing, preventing pressure loss and hydronic leaks.
- Reduced Cycle Fatigue: High-torque motor design handles the demands of continuous circulation in residential and light commercial HVAC applications.
- Precision Compatibility: Designed as a direct drop-in for OEM Part Number 100275607, eliminating the need for field modifications or re-piping during service calls.
Is this pump assembly compatible with all Noble (NKC) series boilers?
This 100275607 assembly is the designated replacement for NKC110L, NKC110N, NKC150N, and NKC199N models. Always verify the specific serial number breakdown as some newer revisions may require different configurations.
Does this unit include the mounting hardware and gaskets?
The assembly includes the critical sealing gasket required for installation. It is a best practice to inspect existing mounting bolts for any signs of corrosion or "scaling" before securing the new pump to the manifold.
Can I use this for domestic hot water (DHW) recirculation?
This pump is engineered for the internal boiler loop and primary circulation. Using it outside of its specified application in open-loop potable water systems may lead to premature failure due to oxygen-rich environments.
