Lochinvar & A.O. Smith 100208413 Pump 319848-301 On the controller endThe Lochinvar & A. O. Smith 100208413 Pump is a critical bypass loop pump engineered for high demand hydronic heating and domestic hot water applications. Designed to maintain precise thermal equilibrium, this OEM circulation pump prevents uneven heat distribution and localized "hot patches" by ensuring continuous fluid movement through the secondary loop. This constant circulation protects the heat exchanger from thermal stress and stagnation,
