The task for our customer near Freiburg was clear; the company, which specializes in sewer renovation, was commissioned to renovate a sewage canal DN 600 in the inner city of Freiburg.

A mobile sewage unit was required to convey the upcoming and changing wastewater volumes. The company decided for a HÜDIG electric sewage pump unit of type EVA 180.

The customer's team was trained on the operation and maintenance of the unit on site. All participants were amazed by the simple operation and the very low maintenance requirements of the unit.

The HÜDIG vacuum generator - also known as a dry-runner - allows the construction personnel to sleep peacefully at night since the first visual inspection is only necessary after 3,000 hours. Due to the low maintenance effort, the construction site personnel can concentrate on the actual task, namely the canal renovation.

3,000 operation hours = 125 days without any maintenance! With this low maintenance effort and this technology, HÜDIG is the market leader for mobile sewage systems with automatic vacuum suction.

In this application, an electric aggregate was used. If a power supply is not available on site, Diesel units of different performance classes are also available. Besides, these machines are also available for rent.

The advantages of the HÜDIG sewage units also appear in the fact that the kind of impellers have been selected in such a way that the user can be sure that the units will work permanently without clogging.

One of the advantages of HÜDIG sewage pump units is also the kind of impellers; those have been selected to ensure permanent work of the units without clogging.

HÜDIG technology – always a good decision!
