Calio glandless heating circulators with thermal insulation shell

The Calio glandless pump brings more efficiency to the boiler room.

Buildings, whether small or large, for private, public or industrial use, requiring a heating or a drinking water system: KSB's broad portfolio of circulators covers a large application range. All glanded pumps of the Calio family are maintenance-free and highly efficient.

The state-of-the-art circulators of the Calio type series for heating and air-conditioning systems are available in the most diverse of variants. Naturally, all our high-efficiency pumps meet the requirements of the ErP Directive regulations applicable since 2015.

The Calio-Therm type series provides safe and efficient drinking water supply: Regular circulation enables you to enjoy hot water as soon as you open the tap, and it prevents the risk of legionella.
