At ISH trade fair (13 to 17 March 2023) in Frankfurt (Main), KSB is showcasing a new type series of fully integrated in-line water pumps. The highly efficient EtaLine Pro type series offers an extremely low energy consumption and an economical use of materials.

By using a hydraulic system designed for high speeds, the developers were able to achieve a very compact design. Thanks to such significantly increased output per size, the new pumps require up to 44 percent less aluminium, 49 percent less grey cast iron and 68 percent less magnetic steel sheet, as well as 73 percent less copper, compared to conventional units.

The magnets used in the motors are classic ferrite magnets, so they do not contain any rare earths, which cause 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 also contribute to this.

The new units have several pump functions, such as Dynamic Control, sensorless control and multiple pump operation, as well as heat quantity measurement. These 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.

With only five hydraulic system sizes, the very quietly operating close-coupled pumps cover a broad selection range.

  • Their maximum flow rate is 63.6 m³/h with
  • the maximum discharge head possible being 42.9 m.

Standardised mechanical seals and a reduced variety of components, combined with an extensive global service network, ensure rapid availability of spare parts when needed. The pumps and the mechanical seals are designed for operating pressures up to 16 bar.

As standard, the pumps are fitted with mechanical seals selected for a maximum operating temperature of 120 °C, depending on the application and the fluid handled. A cathodic e-coating of the cast casings provides the necessary corrosion protection.
