Taco Model 006 Cartridge Circulator (S-50 Model)

The unique replaceable cartridge contains all moving parts, and allows the circulator to be serviced instead of replacing the entire unit. The more quiet direct-drive cartridge type "00" series circulator is self-lubricating, contains no mechanical seal, and requires no maintenance. This compact, low-power consumption design is ideal for those high-efficiency jobs. The built-in Positive D'MAND Valve (PDV) prevents thermo-siphoning and acts as a check valve.

Taco Model 0011 High Velocity Circulator (S-02 Models)

The Taco 0011 high velocity/high head bronze circulator is designed for residential and light commercial systems.

The 0011 has the exclusive "00" cartridge design and ACB motor protector. The "00" cartridge contains all the moving parts; replacing it virtually rebuilds the circulator. The unique ACB anti-condensate baffle with ambient air-flow prevents the buildup of condensation on the motor windings when pumping chilled water. It has a high head medium flow characteristic for applications in high pressure drop boilers, fan coil units, heat exchangers, large radiant heating systems and heat recovery units/earth loop systems.

The quiet, direct-drive high velocity series contains no mechanical seal and requires no maintenance. This compact design has low power consumption and is ideal for those high efficiency jobs that have space requirements. Because universal flange to flange length and orientations are featured, the 0011 may easily replace other models.
