Bell & Gossett Circulator Review
The Bell & Gossett Series PL (Permanently Lubricated) booster pumps are close coupled in line circulator booster pumps. Each pump is built with either an iron or bronze construction and can pump liquids compatible with the pump’s body type. PL series booster pumps are ideal for pressure boosting and water circulating applications in hydronic, radiant, solar, and geothermal heating systems.
PL series booster pumps feature a powerful, dry-motor design which delivers performance ratings that are both more powerful and more efficient than the closest competitors. The shafts are constructed with high-strength alloy steel to resist the cracking that can result from high heat.
All models are lead free. When it comes to a Bell & Gossett Circulator Review you have to think of quality over price. At Inline Sales & Service we sell every brand of pumps and circulators on the market but our go to brand has been Xylem for many years. The Armstrong, Taco, Grundfos and Bell and Gossett circulators all cross over to each other, check out this handy tool for the cross reference.
