TACO 1600 Series In-Line Water Circulation Pumps & Circulators

Taco 1600 Series In-Line Pumps combine the ultimate in reliability with ease of installation and maintenance, for heating, air conditioning, pressure boosting, cooling water transfer, and water supply applications. Quiet, dependable, and proven performance makes the 1600 Series Pump the right choice. Available in 50 Hz and 60 Hz.

Features & Benefits

Quiet, dependable power, and proven performance
1600 Series In-Line pumps meet the latest industry standards for hydraulic performance and reliability. Each is backed by Taco Comfort Solutions a worldwide leader in the design and manufacture of heating and cooling equipment for more than 90 years. Taco “1600” Series In-Line pumps are available in 15 models ranging in size from 1 1⁄2″ X 1-1⁄2″ to 2″ X 2″ with a flow range from 10 to 235 GPM and head capacities up to 68 feet.

Taco 1600 Series In-Line pumps utilize an exclusive replaceable, cooler running bearing cartridge design. This unique design isolates the bearings from the effects of system fluid temperatures which greatly extends bearing life. The cartridge design incorporates permanently sealed grease lubricated ball bearings making it virtually maintenance-free. All 1600 series In-Line Pumps are furnished with ceramic seals (standard) in order to meet a wide range of application requirements. The standard mechanical seal is an industry-standard Type 21 design consisting of the rotating element (SS spring & retainer, EPT elastomers, and carbon mating ring) and ceramic seat. The standardized cartridge design simplifies maintenance with minimal parts requirements, one size cartridge, and a mechanical seal to service the entire product line.

Rugged Casing Design
The 1600 Series has a maximum operating pressure of 175psi, and a maximum operating temperature of 300°F. The 1600 Series is available in cast-iron stainless steel fitted construction or all stainless steel construction.

Cartridge Assembly
Replaceable “cooler running” bearing cartridge extends bearing life, and with permanently sealed greased lubricated ball bearings it is virtually maintenance-free.

Pressure Tappings
Pressure tappings allow for differential pressure readings to be taken across the pump.

One Piece Enclosed Impeller
Dynamically balanced stainless steel impeller assures long life and higher pump efficiencies.

Standard Mechanical Seal
1600 Series In-Line pumps utilize a Type 21 seal design which facilitates quick and easy replacement. Available in ceramic (standard) or the new “Seaside C” (for more aggressive system fluids) ensures the flexibility to meet a wide range of application requirements. One size seal fits all models.

Flexible Coupler
A flexible coupler absorbs shock, vibration, and misalignment that could be transmitted to the cartridge and motor bearings while also isolating and preventing any motor-related noise or vibrations from being transmitted to the system.

Resilient Mounted Motor
A resilient mounted motor ensures quiet reliable vibration-free operation of the pump.

Parts Flexibility
Superior parts flexibility: one cartridge, one seal, and two motor frames fit all pump models.

Factory Tested
All 1600 series pumps are factory tested and are built in accordance with Hydraulic Institute Standards.
