Bell & Gossett 185331 - Spring Coupler, 5/8" x 7/8"

Maintain the peak performance and longevity of your hydronic pump system with the 185331 Bell & Gossett spring coupler. Engineered for precision alignment between the motor and pump assembly, this 5/8" x 7/8" coupling serves as a critical link in ensuring smooth, vibration-free operation throughout your heating or cooling system.

This spring-style coupler is designed to flex under load, effectively absorbing shock and compensating for minor shaft misalignments. By minimizing mechanical stress, it protects your pump seals and bearings from premature wear, ensuring quiet and consistent fluid circulation.

Key System Performance Baselines:

• Durable Construction: Built to withstand the torque requirements of standard hydronic pump operation.
• Precise Fitment: Engineered specifically for 5/8" and 7/8" shaft configurations to ensure secure power transfer.
• System Protection: Acts as a sacrificial component to prevent costly damage to the pump motor and internal mechanical seals.

⚠️ Application Profile: Ideal for residential and light commercial hydronic circulators, boiler feed pumps, and HVAC fluid transfer systems requiring standard Bell & Gossett shaft coupling components.
