One of these is the submersible aerator TRN in the current version, which pumps self-priming ambient air into the wastewater tank to support sewage treatment. The movement that is created protects against deposits. The system competes with the common membrane aerator: in comparison, Tsurumi says the TRN stands free in a tank without the need for building work, does not need a compressor and manages without air voids, which can naturally become blocked up.

The LSC is also shown in action – a small flat suction pump, which removes water from flat areas to a residual height as little as 1mm in continuous operation without supervision. The LSC weighs only 11 kg, pumps up to a height of 11 m and conveys up to 11 m³/h. It is standard equipment for many fire brigade services.
