Crown Engineering H24-36 Spiralink Coupler

The Crown Engineering H24-36 Spiralink Coupler is a heavy-duty, single-spring replacement solution engineered for HVACR circulator pumps. Designed to replace the traditional failure-prone OEM multi-spring "fly-away" couplings, this 5/8" x 5/8" CCW coupler features a robust one-piece construction that significantly reduces friction and mechanical noise. The counter-clockwise (CCW) rotation and dual 5/8-inch bore diameters ensure precise alignment between the motor shaft and pump assembly, specifically for Bell & Gossett and Armstrong series pumps. By utilizing a high-tensile Spiralink spring, this component acts as a torsion-absorbing interface, compensating for minor shaft misalignment that typically destroys standard couplings. Contractors often prefer the H24-36 for its "set it and forget it" reliability in high-torque commercial heating environments. It is a direct fit for 3450 RPM and 1750 RPM motor applications, protecting bearing assemblies and seals from the jarring impact of motor startups without the risk of individual spring breakage.

Key Benefits
  • Enhanced Torque Absorption: The single-spring Spiralink design acts as a shock absorber, reducing stress on the motor and pump bearings during high-torque startup cycles.
  • Quiet Operation: Eliminates the rattle and vibration associated with aged or failing 4-spring OEM couplers, ensuring smooth power transmission.
  • Simplified Installation: The compact, one-piece body allows for faster swaps in tight mechanical rooms without requiring a "third hand" for alignment.
  • Misalignment Tolerance: High-flex 5/8" coupler geometry accommodates the slight shaft deviations common in aging boiler circulators and in-line pumps.
Common Questions

Is the H24-36 compatible with CW rotation pumps?
No, the H24-36 is specifically designed for CCW (Counter-Clockwise) rotation. For clockwise applications, the H24-34 model is required to ensure proper spring tensioning.

What pump series does this Spiralink coupler replace?
This model is a high-performance replacement for Bell & Gossett 1510, 1531, and Series 60 pumps, as well as Armstrong S & H series circulators utilizing 5/8" shafts.

Does this coupler require regular lubrication?
The Crown H24-36 features a maintainance-free design with no moving parts to produce friction, eliminating the need for periodic lubrication schedules.
