Lochinvar & A.O. Smith 100166325 Pump
The Lochinvar & A.O. Smith 100166325 Pump Less Volute is a heavy-duty centrifugal circulator pump component engineered for high-efficiency commercial water heating systems. This replacement pump motor and impeller assembly is designed for rapid integration into existing volutes, minimizing downtime during critical hydronic repairs. Built with a high-torque motor and precision-balanced impeller, it maintains optimal flow rates in Lochinvar Knight and A.O. Smith Cyclone series boilers. The unit features a three-piece design that allows for serviceability without breaking piping connections. Technicians should verify pump flange alignment and motor lead configurations to ensure seamless electrical integration. This OEM replacement part provides the hydraulic performance required for high-head pressure applications, ensuring the heat exchanger receives consistent flow for thermal stability. By utilizing this high-temp circulator, contractors can restore system pressure and prevent overheating cycles in large-scale domestic hot water loops.
Key Benefits
- Precision mechanical seal construction prevents leakage under high-pressure commercial operating conditions.
- Drop-in motor and bracket assembly reduces labor hours by utilizing the existing pump housing.
- Directly compatible with Lochinvar part number 100166325 to ensure electrical and hydraulic synchronization.
- Heavy-duty shaft sleeve design protects the motor shaft from corrosion and sediment buildup.
- Balanced impeller geometry reduces vibration and noise across the entire modulation range.
Common Questions
Is the volute or pump housing included with this part?
No, this is a pump less volute assembly, commonly referred to as a replacement cartridge or motor kit. It is designed to be installed into your existing pump housing.
Which boiler models are compatible with the 100166325?
This circulation pump is typically used in Lochinvar Knight (KBN) and A.O. Smith commercial water heaters, specifically models requiring high-volume fluid transfer for heat exchange.
Does this assembly include necessary gaskets for installation?
Standard installations usually require a specific flange gasket or O-ring; it is recommended to verify the condition of the existing seat before securing the motor to the volute.
