Taco ES2 ADAPT 70 Circulator Pump


Premium high efficiency Taco ES2 ADAPT 70 circulator for heating systems. Taco ES2 ADAPT is a wet rotor high efficiency circulator, driven by a permanent magnets synchronous motor (PM motor) controlled by an on board inverter. The motor is protected against overload thanks to a thermal protection and an automatic electronic release function of the rotor. No external protection is required. Operated by selector technology. LED user interface.

Featuring activeAdapt mode for easier and faster installations

Taco Circulator pumps can be used as alternatives to other leading manufacturers products including DAB and Grundfos. Full a full list of pump equivalents click here. If you require any help with product selection please call or email.


Suitable for all kinds of Hot-water heating systems in domestic and commercial applications.
Heating bills are one of the most expensive expenditure:

80% of the annual household energy consumption is primarily due to heating living spaces, followed by domestic water heating. It is therfore extremely important that high efficiency systems are installed in houses so as to cut down on unnecessary consumption.

Taco Flow Solutions circulators are designed with innovative technology which are able to reduce power consumption and optimize system performance by promptly responding to its demands, thus preventing unnecessary waste.


– Highly efficiency due to Taco permanent magnets motor
– Compact design: the smallest available on the market
– A LED provides information about the operation status of the circulator
– active ADAPT mode
– Electronic controls allow to set advanced features and load adjustment capacity Δp-c (constant differential pressure) and Δp-v (proportional differential pressure)
– Min-Max mode: allows to set the exact working point across the range
– The pump housing is cataphoresis treated (KTL) and resistant to corrosion
