New in-line pumps for building services applications

news item image
KSB is ready to launch a new series of fully integrated in-line water pumps.
The EtaLine Pro type series has been developed to offer extremely low energy consumption and the economical use of materials for intelligent and highly efficient performance.
By using a hydraulic system designed for high speeds, KSB’s designers were able to achieve a very compact design. Thanks to a significant increase in output per size, the new pumps require up to 48% less aluminium, 49% less grey cast iron. 68% less magnetic steel sheet and 73% less copper compared to conventional units.
The classic ferrite magnets used in the motors do not contain any rare earths, which are a cause of great environmental damage during their extraction. The motor rating ranges from 0.8 to 2.6 kW. With their wide voltage range of 380 to 480 volts at 50 or 60 Hz, the pump sets can be used worldwide.
The international product certifications such as CE, UKCA and UR/UL are contributing factors to their suitability for world-wide acceptance.
Suitable for applications including heat transfer, cold water transfer (acclimatisation) and many types of water transportation, the new units offer a high degree of planning reliability, as they have several pump functions. Examples include dynamic control, sensor less control and multiple pump operation, as well as heat quantity measurement.
These intelligent functions allow adjustments to be made to the operation or operating points even after the pumps have been installed. The pumps adjust their flow rate and head based on an algorithm, moving the operating point along a programmed control curve. Thanks to various digital interfaces, integration into modern building management systems is possible without any problems.
