Auburn Ignitors 10023 Spiralink Spring Pump Coupler 1/2 to 3/4 HP

The Auburn Ignitors 10023 is a single spring pump coupler designed for use with circulating pumps in HVAC and hydronic heating systems. This Spiralink-style coupling features a unique spiral spring design that connects the motor shaft to the pump shaft, rated for motors from 1/4 to 2 HP.

Key Features:

• Shaft compatibility: 1/2" x 1/2" or 1/2" x 5/8" shaft diameters
• Power rating: 1/4 to 2 HP (commonly used on 1/2 to 3/4 HP motors)
• Single spiral spring design absorbs start-up torque and reduces vibration
• Tolerates shaft misalignment in three dimensions for easier installation
• Operates quietly compared to traditional multi-spring couplers
• Clockwise rotation only

This coupler serves as a direct replacement for Bell & Gossett part numbers 118473, 118708, 118709, and P77234, as well as Armstrong part numbers 807436 and 806137. The spring coupling design provides a permanent, reliable alternative to failure-prone traditional four-spring "fly away" style couplers commonly found in circulator pumps.

Note: This part number is typically manufactured by Crown Engineering/Spiroflex. Auburn Ignitors primarily manufactures combustion igniters and flame sensors, so verify the correct manufacturer if ordering directly.
