The KSB Group will launch the high-efficiency Calio Pro series in July 2022
As an extension to its range of high-efficiency glandless pumps with continuously variable speed control, the KSB Group launched the Calio Pro type series in July 2022.
Available in screw-ended or flanged designs, the new pumps have been developed for recirculation systems in larger buildings, such as heating, ventilation and air-conditioning systems.
With their high efficiencies, the new pump sets already meet the requirements of future energy efficiency regulations. Thanks to the integrated intelligent DynamicControl program, additional energy savings of around 40 percent can be achieved compared with conventional proportional-pressure control.
As the function is purely based on software, no additional costs will be incurred by further sensors or actuators. The pumps automatically gather all required information from their internal signals. The program rules out undersupply in the event of changing system conditions.
The new type series is available in 25 sizes and can handle flow rates of up to 24 m3/h at a maximum head of 12 mWC. The Calio Pro series includes a volt-free general fault message as standard for simple forwarding to a building services control station.
Without additional software or hardware modules, two pumps – one used as duty pump, the other as stand-by – can be operated in parallel with automatic changeover in the event of a fault as well as timer-controlled pump changeover. Often this allows investment and commissioning costs to be kept to a minimum.
Installation and commissioning are very simple, as all operating modes, functions and setpoints can be adjusted using keys on the control panel display. The user is shown the set head or, in open-loop control mode, the speed level. Unauthorised manipulation of the operating parameters can be prevented by locking the keypad.
The fluid temperature range from -10 °C to +110 °C makes the new pump sets suitable for a wide variety of applications, from heating water to coolant transport and industrial recirculation systems. The pumps are also available in a twin pump configuration as Calio Pro Z.
