Groundwater lowering - efficiency, sound insulation, functionality

Bauma 2022 - Groundwater lowering

We would like to thank all visitors of our booth at the Bauma 2022 in Munich! Our appearance was all about efficiency, sound insulation and functionality. We presented top sellers, such as the particularly quiet HC 488 Whisper and the fuel-saving HC 522/17, as well as innovations in the field of groundwater lowering. The new HC 272/02 Elektro piston pump was presented to the public for the first time and received a thoroughly positive response. A diesel version is already in the starting blocks.

The HC 551/31, also known as the "Whisper 6", is a diesel-powered powerhouse that impresses with its compact design and particularly high vacuum and pumping capacity. The versatile pump unit is powered by a 3-cylinder Hatz stage 5 engine.

The HC 468 Whisper SL (Slim Line) is HÜDIG's response to the increasing demand for a particularly compact, electrically operated and quiet unit for groundwater lowering. Especially in urban construction areas, where a low noise level plays an important role, the fully automated electric unit shows its full strength. A total of three HC 468 Whisper SL units can be stacked on top of each other to guarantee high-yield storage!

In the wastewater sector, too, the focus was on minimizing noise emissions. We exhibited the new EVA 350 Whisper wastewater vacuum unit. The unit offers a pumping volume of max. 600 m³/h, and that at a whisper-quiet sound pressure level (LPA) of 44 dB(A) at 7 m and 42 dB(A) at 10 m.
