More Information
(pdf file)


     Spiralink™ is a permanent replacement for the failure-prone 4-spring, "fly away" coupling used as original equipment in B & G circulators and clones by Armstrong, White-Rogers, Taco, and others.

     Spiralink™'s single spring acts as a universal joint with 3-dimensional flexibility that compensates for any degree of shaft misalignment.  The one-piece design has no connecting parts to produce the friction that causes noise, wear and early failure of old-style couplings.

     Spiralink™ protects bearing assemblies from damage by broken couplings, and its flex reduces the torque load on bearings and seals.  On top of that, it's far easier to install, especially in awkward locations.

     Four Spiralink™ models cover the whole range of B & G pumps up to 1 HP at 1750 RPM (Up to 2 HP at 3450 RPM), and the Taco series 121 - 138.
