Connections - takeoffs: G1 ”1/2 - 130 mm - Rotation speed: 800 ÷ 4250 rpm

Low energy consumption electronic pump for circulating hot water in all types of heating and solar energy systems.

Thanks to the advanced technology employed, the permanent IM-E synchronous motor and the frequency converter, the new range of IM-E circulators guarantees high efficiency in all applications, with significant benefits in terms of energy savings.

The pump has a built-in electronic device that detects the changes required by the system and automatically adapts the pump's performance accordingly, always ensuring optimal efficiency and minimal energy consumption.

The IM-E series is also suitable to replace old three-speed circulators, as far as size is concerned, as it has the same dimensions as the old series.

Optional frame for 700 stove in black.

Expansion vessels for domestic hot water systems in steel.

All vessels equipped with stainless steel flange cover.

Heating up to 65º.

This aluminum alloy used is a guarantee with regard to quality and compliance with standards, offering good thermal conductivity, mechanical resistance, durability and corrosion resistance.
