| The Bell & Gossett 1BL032, also known as the Model PL-55, is a dependable cast iron circulator pump designed for efficient hydronic, radiant, and geothermal heating and cooling systems. This close-coupled pump features a permanently lubricated, single-phase motor that operates at 115 volts and delivers 2/5 horsepower at 3250 RPM. In layman's terms, it uses an electric motor to spin an impeller, which creates a force that circulates water throughout your heating or cooling system. Unlike some pumps, the PL-55's dry motor design keeps the working parts isolated from the water stream, reducing maintenance needs and improving efficiency. Furthermore, the advanced close-coupled design and non-metallic impeller allow this pump to handle a wide range of water conditions and temperatures, making it a versatile choice for various HVAC applications. Weighing in at around 16 pounds, the 1BL032 is a powerful and reliable workhorse that can contribute to the overall comfort and efficiency of your HVAC system. |
