The motors, named after Lake Tuma, the source of the Rhine river, comply with efficiency class IE3, offering high reliability and durability, even under extreme conditions. They meet the highest efficiency standards in the industry without relying on rare earths in production. This contributes to a sustainable production process and a small footprint.
Thanks to flexible combination options in Hidrostal's modular system, they are suitable for a wide range of applications, including aggressive media such as seawater. An innovative sensor system, maintenance-friendly design and certified explosion safety (IECEx, ATEX, FM, FMc in progress for certification) make Small Tuma motors ideal for demanding industrial applications.
The Small Tuma motors are characterized by a fully cast outer shell and a patented cooling system that enables reliable operation even under the most difficult conditions. Durable components such as ball bearings with a service life of at least 50,000 hours and mechanical seals ensure maximum durability and reliability. A comprehensive sensor system monitors the bearing condition as well as the mechanical seals and enables connection to Industry 4.0 systems, such as HidroSmart - an intelligent platform for monitoring and controlling pump systems that evaluates data in real time and enables early fault detection - ensuring maximum operational reliability. Bimetallic switches, PTC sensors and optional PT100 sensors protect the windings from overheating. The motors are certified according to IECEx, ATEX, FM and FMc (in the certification process) for use in potentially explosive atmospheres.
Ease of servicing was a key objective in the development of the Small Tuma motor range. The motors have plug-in connection cables that can be left on site for servicing. All components are designed so that they can be replaced with a minimum of tools, and the smooth surface of the motors facilitates cleaning and maintenance. For maximum flexibility, the motors can be installed both vertically and horizontally and can be supplemented with certified suspensions or maintenance-friendly base plates.
