Pump Coupler Sleeve 3J

The Bell & Gossett 185330 is a circulating pump coupler sleeve designed for in-line circulating pumps. It serves as a direct replacement component for compatible pump assemblies. This part is intended for plumbing professionals and maintenance technicians servicing hydronic heating or cooling systems. It restores the mechanical connection between the motor and pump body.

Fits E-60 and 60 Series

The sleeve fits pump models 623S and 624T within the E-60 and 60 series families. It replaces the original coupling without requiring modification to the pump housing or motor shaft. Installation frees the technician from sourcing separate rubber and metal hardware. The component bridges the drive connection to return the pump to operational status.

Rubber and Zinc Construction

The coupling material combines rubber with zinc to absorb vibration and tolerate misalignment. This construction dampens operational noise and reduces wear on motor bearings. The one-year manufacturer warranty covers defects in materials and workmanship. No additional accessories or software are included with this sleeve.

Questions about this item

What is the first limit reached during sustained operation of the 185330 coupler sleeve?

The rubber and zinc coupling material will degrade from continuous heat and mechanical stress before any other factor becomes critical.

How much heat or noise does the 185330 generate when running all day?

The sleeve itself produces no heat or noise; it transmits vibration from the pump, so levels depend on the specific pump model installed.

Which Bell & Gossett pump models must I already own for the 185330 to fit?

It fits in-line circulating pumps in the E-60 and 60 series families, including models 623S and 624T.
