Quiet, dependable power and proven performance.
Taco Vertical Inline Pumps meet the latest standards for hydraulic performance and dimensional characteristics. With the addition of seven new models, Taco expands its hydraulic coverage to flows up to 2500 GPM at heads up to 300’ TDH.
Quiet, dependable power--Proven performance.
Taco’s extensive line of vertical inline pumps are designed for optimum performance and ease of installation. Doing your job once means doing it right...with pumps made by the world leader in hydronic technology for heating and cooling. Each pump we sell is backed by Taco’s reputation for quality and dependability, and engineered for years of trouble-free service.
Space Saving Design Taco vertical inline pumps require no isolation pads. Their simplified in-the-line design saves you time and money.
Back Pull-Out Design Should a service call or maintenance ever be required, our pumps pull out from the back. There’s no need to disconnect the pump from the piping system to work on it.
Close Coupled Design Each vertical inline pump features Taco’s close coupled design for improved alignment and increased seal life. The bottom line? Fewer service calls.
Lower Installed Cost Because of the way we’ve engineered our pumps, they require less time to install, and require no special tools or hardware.
Direct or Split Coupled? We provide either configuration to improve serviceability on large horsepower pumps (See Catalog 300-1.3 for Split Coupled). What’s more, the seal can be serviced without removing the motor.
We’ve got you covered With flows ranging up to 2500 GPM at heads up to 175’TDH,Taco can do the job.
VI Pumps are available in capacities up to 2,500 GPM at heads up to 175 Ft. TDH. Product Selection and Specification is simplified through the use of the TacoNet Software System. For specific selection/application information, please download the TacoNet Software.

Furnish and install centrifugal in-line single stage pump(s) with capacities and characteristics as shown on the plans. Pumps shall be Taco model VI or approved equal.
Pump volute or casing shall be constructed of class 30 cast iron. The pump can be fitted with replaceable bronze wear rings, drilled and tapped for gauge ports at both the suction and discharge flanges and for drain port at the bottom of the casing. The pump shall be capable of being serviced without disturbing the system piping.
The impeller shall be bronze and hydraulically balanced by either back vanes or back wear ring and balance holes. The impeller shall be dynamically balanced and shall be fitted to the shaft with a key.
The pump shall be close coupled to a NEMA standard JM motor. The pump shall incorporate a dry shaft design to prevent the circulating fluid from contacting the shaft. The shaft shall be covered with a replaceable bronze (stainless steel) shaft sleeve.
The pump shall have a factory installed vent line running from the seal chamber and connecting to either the pump discharge or pump suction to insure removal of trapped air and cooling of the seal. Extend seal life is accomplished with an optional seal flush line and/or sediment separator running from the pump discharge to the seal chamber.
The pump seal shall be EPT Ceramic rated to 250 Deg. F. (EPT Tungsten Carbide rated to 300 Deg. F.). Optional seal materials and elastomers are available.
