circulation pump dab EVOSTA2
circulation pump dab EVOSTA2DAB's Evosta 2 electronic wet rotor circulators are designed for water circulation in domestic heating and air conditioning systems.
Evosta 2 are equipped with a synchronous motor with permanent magnets and electronic unit with a frequency converter that automatically adjusts the characteristics to the requirements of the system, providing energy savings and protecting the system from hydraulic shocks.
The model is ideal for replacing old three-speed circulation pumps, thanks to both its compact size and as well as the configuration offered in the delivery set. This model combines the strength of a mechanical circulation pump and the advantages of an electronic one.
The model is easy to set up: with one button you can sequentially select from nine operating modes: three with proportional differential pressure, three with constant pressure drop and three with constant speed. All models are equipped with an air bleed plug and allow manually unlock the motor shaft. Suction and pressure pipes with threads. Impeller made of techno-polymer. Pump housing — cast iron with cataphoresis coating, motor housing made of stainless steel. All electronics are waterproof with IPX5 protection level.
