TVB In-Line Centrifugal Pumps

TVB Series Thrush Pumps are in-line, vertical, cast bronze, close-coupled, centrifugal pumps specifically designed for quiet, efficient operation in hydronic heating and air conditioning systems. 

The TVB’s casing design allows for quiet performance and cost efficiency. 

Improved bracket design incorporates a diverging seal chamber that creates a vortex action which stimulates circulation within the seal chamber. 

Circulation is necessary to eliminate air and foreign particle buildup and carries off frictional heat developed at seal faces. 

The TVB bracket also incorporates internal flush line which increases recirculation in the seal chamber and provides manual venting. 

The TVB offers a back pull out design which allows for maintenance without disturbing existing piping. 

Shaft wear and corrosion are prevented by the bronze shaft sleeve. 

The TVB offers a 4 bolt ANSI flange pattern and ceramic seal.
