Lochinvar & A.O. Smith 100166430 Pump

The Lochinvar & A.O. Smith 100166430 Pump is a high-performance 1/6HP circulator pump designed for reliable fluid transfer in commercial and residential hydronic systems. Operating at 115V and a fixed speed of 3250 RPM, this unit features a counterclockwise lead end (CCWLE) rotation, ensuring precise flow dynamics for domestic water heater and boiler applications. It is the direct OEM successor and identical to PUM3010, engineered to integrate seamlessly without piping modifications. With a weight of approximately 11 to 16 lbs and a durable bronze or cast-body construction, it supports high-head requirements up to 9250lb/hr capacity. This centrifugal pump is commonly utilized in Lochinvar AWN and WAN series units, providing the necessary lift for efficient heat exchange. For technicians, the 100166430 replacement pump offers a drop-in solution to restore system pressure and thermal consistency in demanding HVACR environments.

• Direct OEM Compatibility: Serves as a 1:1 replacement for the discontinued Lochinvar PUM3010, maintaining original factory specifications.
• High-Speed Efficiency: The 3250 RPM motor provides the high-velocity circulation required for modern high-efficiency water heaters.
• Industrial Build Quality: Designed for continuous duty cycle and thermal endurance in boiler loop applications.
• Simplified Installation: Standardized flange mounting and 115V 1PH electrical requirements reduce field labor time.
