This Lochinvar variable speed pump, also known as the FB5000, is a high-performance device designed to regulate the flow of water in heating and cooling systems. It operates on a variable speed mechanism, which allows it to adjust its output based on the system's demand. This feature ensures optimal energy efficiency and reduces operational costs. The pump has a maximum head of 60 feet and a maximum flow rate of 132 gallons per minute (GPM), making it suitable for large-scale applications. Its robust construction includes a cast iron casing for durability and an electronically commutated motor (ECM) for reliable performance. The FB5000 is also equipped with advanced controls that provide real-time feedback and enable precise adjustments to meet specific system requirements.
