Taco is at the forefront of circulator innovation. Their drive to provide the most efficient, reliable pumps in the industry can be seen across their entire catalog. The Taco 138 is an in-line cartridge design pump. Models 121 through 138 all share the same mechanical seal and cartridge bearing assembly, a design that Taco has perfected. An open drip proof enclosure and overload protector are standard on the 138's motor, guarding it against dangerous conditions. Built for efficient circulation in both hydronic heating and cooled water chilling systems, the 138 is a versatile, hardy circulator that can handle a variety of applications and conditions. A low maintenance design is coupled with durable components to provide you peace of mind. With Taco, your hydronic circulation is in good hands.
A rubber drive coupling absorbs any vibrations from misalignment to keep your circulator running smoothly. Taco used to sleeve bearings to keep the 138 nice and quiet. Every in-line cartridge circulator is factory tested before it is shipped out to you
The replaceable cartridge with sealed, lubricated bearings rarely requires attention. The bearings are held separate from extreme system temperatures in this cartridge, extending their longevity.
