IBECO granted patent for mobile pump chamber

We have been granted a patent in Sweden for the mobile pump chamber, a solution that drains water-filled trenches quickly and safely, without anyone needing to climb down into the pit. We are now taking the next step and seeking distributors in Europe.

A simple solution to a common problem

High groundwater and water-filled trenches are an everyday challenge in groundworks and water and wastewater projects. Work grinds to a halt, pumps clog up, and personnel are exposed to risks in unstable trenches.

The mobile pump chamber consists of an outer installation pipe with a standardised S60 fitting and an inner perforated pipe. The chamber is placed at the correct depth using the excavator, the gap is filled with crushed stone, and the outer pipe is pulled up. What remains is a stable, drained chamber into which a submersible pump or a suction hose can be lowered.

"The patent confirms that we have developed something unique. The mobile pump chamber makes trench work safer and more efficient, and we see that the need exists well beyond Sweden's borders," says Erik Berglund, CEO of IBECO.

The idea came from the field

The inventor, Richard Wennberg, who works in water and wastewater within municipal operations, grew tired of battling pumps in waterlogged trenches. He came up with the idea for the pump chamber while standing in a pit himself. He brought it to IBECO, and together we have developed it into a finished, now patented, product.

"I wanted to stop standing in water fixing clogged pumps. It feels fantastic that the solution is now patented and can reach out across Europe," says Richard Wennberg.

Benefits of the mobile pump chamber

• No personnel need to work in water-filled or unstable trenches

• Smaller trenches, fewer transports and a faster process

• The pump is protected, resulting in less wear and fewer blockages

• Reduces the need for vacuum tankers and works in most ground conditions

Patented in Sweden, patent no. SE 548 712. An international patent application (WO 2026/063847) has been filed.
