Measuring 0.5 inches by 0.5 inches, this coupler transfers rotational force between the motor shaft and pump shaft while allowing for minor misalignment. It is a direct-replacement component installed by licensed plumbers and HVAC technicians during pump service or motor changeouts. The spring-type design absorbs vibration and reduces shock load on both the motor and pump assembly, making it a practical choice for maintaining reliable system operation in heating applications.\u003c\/p\u003e\n\u003cp\u003eThis coupler is rated for heating applications and fits the 2.5-inch pump series as well as LD-3, HD-3, HLD-3, and HHD-3 series pumps from Bell Gossett.
