For use in closed loop heating where hydraulic separation is required between the boiler and the connected loads. Ideal for use with condensing boilers having high resistance or when total flow rate of all parallel running circulators is higher than the maximum flow rate of the boiler.

Simplified installation and reduced assembly times provide for significant cost and labor savings over traditional site built systems.

Exclusive PAW union connections make mounting and connection of the pump modules fast, easy and leak free.
