The Aquapump Medium pumping station is the first choice when it comes to the disposal of wastewater below the backwater level in single households.
The internal diameter of the installation chamber is 600 mm and offers enough space for different versions: It is available as a Mono or Duo system with pumps in different performance classes for both faecal-free and faecal water. In addition, you can choose between level detection with a float switch or innovative pressure sensor. There are versions for installation depths of up to 1,800 mm, which are groundwater-resistant up to a depth of 2,500 mm depending on the model.
Convenient Installation: The station features low weight of chamber components, a high degree of pre-fabrication, fixed connecting pieces for inlet and pressure pipe, enabling fast and easy installation.
Maximum Safety: Available with pressure sensor for precise level measurement. The pump conveys water through the pressure pipe into the sewer at maximum level. The control unit integrates an SDS self-diagnosis system.
Adjustable Upper Section: Height adjustable by up to 500 mm for easy adjustment to ground level.
