Lochinvar & A.O. Smith 100166435 Pump
The Lochinvar 100166435 Pump, also identified as the KB285 pump assembly, is a high-performance circulation component engineered for specific Lochinvar Knight and A.O. Smith high-efficiency boilers. Designed for domestic hot water (DHW) and closed-loop hydronic heating applications, this pump features a heavy-duty cast iron or stainless steel housing to withstand demanding thermal cycles. For technicians replacing 100166435, it is vital to verify flange-to-flange dimensions and amperage draw to ensure the system’s circulator pump curve matches the original specifications. This OEM Lochinvar replacement part maintains optimal flow rates through the heat exchanger, preventing overheating and ensuring consistent BTU transfer. Proper installation requires inspecting the pump gaskets and checking the electrical terminal box orientation for terminal block clearance. By utilizing this genuine A.O. Smith commercial pump, contractors ensure seamless integration with the existing variable speed control logic on the boiler’s control board, maintaining system hydraulic balance.
- Direct OEM Compatibility: Built to the exact specifications for Lochinvar KB285 series boilers, ensuring precise fitment without piping modifications.
- High-Efficiency Performance: Engineered for hydronic circulation, optimizing flow resistance and reducing energy consumption in commercial applications.
- Durable Construction: Features high-grade internals designed to resist cavitation and scale buildup in high-temperature environments.
- Hydraulic Optimization: Corrects short-cycling and low-flow errors by restoring the factory-specified pressure drop across the heat exchanger.
Common Questions
Is the 100166435 pump compatible with other boiler brands?
While A.O. Smith and Lochinvar share many components, this part is specifically calibrated for the flow requirements of the Lochinvar Knight XL and compatible A.O. Smith commercial water heaters. Always cross-reference your specific model and serial number.
Does this pump include the required gaskets?
Standard Lochinvar pump assemblies typically include the necessary mounting gaskets; however, it is professional practice to inspect the flat-faced flanges for debris or pitting before installation.
What are the symptoms of a failing 100166435 pump?
Common indicators include high-limit manual reset trips, flow switch errors, or internal humming without water movement, often caused by a seized impeller or a failed capacitor.
