The KSB Group has launched the Calio Pro type series as an extension to its range of high-efficiency glandless pumps with continuously variable speed control.
Available in screw-ended or flanged designs, the new pumps have been developed for recirculation systems in larger buildings, such as heating, and ventilation.
Thanks to the integrated intelligent DynamicControl programme, additional energy savings of around 40% 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 programme 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 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.
