Calio

KSB Calio - The highly efficient premium pump for versatile applications The KSB Calio is a maintenance-free, highly efficient wet-rotor pump that has been developed as a premium solution for a wide range of applications in heating and air conditioning technology. Whether as a heating pump, hot water heating pump, circulation pump or circulation pump for radiators and underfloor heating systems - the Calio impresses with its first-class energy efficiency and versatility. Construction and design - Maintenance-free, highly efficient wet-rotor pump (glandless) - Pumped liquid-lubricated special plain bearing Drive - Highly efficient permanent magnet synchronous motor, brushless and self-cooling - Infinitely variable differential pressure control - Integrated motor protection - Electrical data: 1~230 V AC +/- 10%, frequency 50 Hz/60 Hz - Protection class: IPX4D - Thermal class: F - Temperature class: TF 110 - Energy efficiency index (EEI): ≤ 0.20 - Standards: Interference emission according to EN 61000-6-3, interference immunity according to EN 61000-6-1 Connections - Screw or flange connection Operating modes - Constant pressure control - Proportional pressure control - Temperature-controlled differential pressure control (can be activated with KSB ServiceTool) - Actuator operation with setpoint specification - Eco mode Pumped media - Heating water according to VDI 2035 - Water-glycol mixtures (up to a mixing ratio of 1:1) Special features Thanks to the integrated differential pressure control, the Calio adapts dynamically to the requirements of the respective system, which not only increases comfort but also reduces operating costs. The use of ceramic bearings ensures reliable and quiet operation as well as a long service life. The insulation shell supplied also reduces heat loss and increases efficiency. The Calio impresses with simple and intuitive operation, a clever and space-saving design and integrated interfaces such as MODBUS RTU. The pump meets the highest standards of energy efficiency and exceeds the current requirements of the ErP regulation. In addition to heating and hot water systems, its possible applications also include air conditioning systems and closed cooling circuits. Available in different sizes and variants, the KSB Calio offers an optimum solution for almost any requirement - from small households to large industrial systems. Experience the future of pump technology with the KSB Calio - your high-efficiency pump for the highest demands.
