Xylem-Bell & Gossett Spring Type Pump Coupler

The Xylem-Bell & Gossett Spring Type Pump Coupler is a replacement pump coupling for Bell & Gossett in-line hydronic circulator pumps. It connects the motor shaft to the pump shaft. It transmits rotational torque and absorbs the slight shaft misalignment that develops during installation and normal operation. The coupler is also called a circulator pump coupling or motor coupler.

Key Features:

• Spring-type design that transmits torque through a flexible spring element
• Accommodates minor misalignment between the motor and pump shafts
• Genuine Bell & Gossett replacement part for hydronic heating and cooling circulator pumps
• Intended for fractional horsepower motors
• Available in different shaft size configurations to match specific pump series

The coupler is a common wear item. It is designed to wear before the motor or pump body is damaged. A broken coupler often means the motor mounts have lost their resiliency and the shafts are out of alignment. Replace the motor mounts at the same time to help the new coupler last. Choose the variant that matches your pump's shaft sizes.
