Vertical turbine generators are actually reverse running pumps which when the flow that runs through the pump is reversed, the impeller starts turning in the other direction and the pump operates as a turbine. The motor that drives the pump can work also as a generator; when it’s working as a turbine, it collects the mechanical energy and transforms it into electricity. The VTG is particularly suited to where the head and flow are consisteng, and its main purpose is to fill small hydroelectric needs, and others.

The majority of the Ruhrpumpen product catalog has been loaded into GPS. Many lines are available for immediate access without requiring a login. Those product lines shown in gray are only available with a user account.

In addition to the curve selection capability available for public access, GPS provides Ruhrpumpen the ability to generate complete quotation packages internally. This will allow faster responses to customer inquiries.

While GPS is a powerful tool it cannot handle all situations. Certain product lines and conditions are beyond the capabilities of anything but an experienced Application Engineer. Please contact Ruhrpumpen for assistance with any application, small or large.

Usage note: GPS will launch new sessions or pop-ups for user option selection and other functions. Your browser’s pop-up settings may require adjustment for these to function properly.
