Electronic circulation pumps EVOSTA2 with a synchronous permanent
magnet motor and frequency converter, designed for heating and air-conditioning systems.
The EVOSTA2 range of circulation pumps ensures high efficiency in all applications and
brings significant energy savings. The pump includes an electronic device
for detecting pressure changes in the system and automatically adapts its output, which ensures
maximum efficiency with minimal energy consumption.
The circulation pump EVOSTA 2 is also suitable for replacing old three-speed
circulation pumps, as it has the same overall length and connection as, for example,
the VA range, and is able to cover, with a single pump type, a head of 4, 5 and 6 metres.
All models have an air-vent plug and allow manual release of the motor shaft.
The cast-iron body has a cataphoretic coating, the casing is made of stainless steel. Waterproof electronics
with IPX5 protection class.

EVOSTA 2 has a single sequential button for all settings and is fitted with an air-vent
plug for venting the system, and for the possible release of the shaft.
