28 basic sizes in a single-stage or multi-stage design allow maximum flexibility even during the planning stage. This means that the GVSO covers volume flows of up to 4.000 m3/h and pumping heights of up to 150 m. Individual immersion depth adjustment from 0.5 to 17,5 m through the use of one or more intermediate bearings completes the maximum level of flexibility.

At the customer‘s request, the connecting dimensions and the shape of the sole plate  can be individually adapted to the container and pressure flange. If constant temperatures and viscosities are required, e.g. in the case of molten sulphur, the GVSO is also available as a heated version. Here we offer a customised heating jacket system for steam and other heat transfer media. Only two additional connections for feed and discharge are required here.

The pump is equipped with the i-ALERT®2 sensor as standard. This monitors vibrations and temperature. If preset limit values are exceeded, LEDs in the sensor light up. All measured values can be retrieved via an app or the Ai Platform. This means that necessary measures can be taken in good time before the pump fails.
