©Taco Catalog #100-162 Eective Date: 03/05/21

Supersedes: 02/01/21 Printed in USA

The 0026e™ is a high-performance, variable speed, wet-rotor circulator with high-eciency

ECM permanent magnet technology. With 5 easy settings, its variable speed performance

curves are equivalent to the Taco 0010, 0011, 0012, 0012 3-Speed, 0013, 0013 3-Speed & 0014.

Ideal for large residential and light commercial hydronic heating, chilled water cooling and

domestic hot water systems.

The 0026e reduces power consumption by up to 85% compared to equivalent AC permanent

split capacitor circulators. With a maximum of 26 feet of head and 44 gpm, it is available in

either Cast Iron or NSF certied Stainless Steel.
