Bell & Gossett 1BL032 PL-55 cast iron booster pump, 2/5 HP, 3250 RPM, 115V single-phase, 0-50 GPM flow range, 150 PSI max pressure, 225°F max temperature. Compact close-coupled circulator for hydronic heating and cooling closed-loop systems.

Series PL pumps are dependable, in-line cast iron close coupled booster pumps used for hydronic, radiant and geothermal heating and cooling systems. The Series PL features a maintenance-free system, with a self-cleaning particle shield protects the shaft and bearings from system start-up debris. The unique XL11 precision-crafted bearing system also contributes to trouble-free start-ups. A powerful, dry-motor design offers 25% more efficiency than the competition. Unlike a wet rotor, the Series PL does not need to bypass system water through the motor to lubricate and cool the bearings. The PL's advanced close-coupled design increases pump life and efficiency. The Series PL's stabilized heat-resistant, non-metallic impeller with a closed design improves overall operating efficiency. Unlike larger wet rotor circulators of similar performance, the Series PL is able to handle difficult water conditions at a wide range of temperatures. Mounting hardware and flange gaskets are included with the pump. Flanges are available separately in 3/4", 1", 1-1/4", and 1-1/2".
