Feed pipelines bring waste water to the lower suction part of the station (suction tank), at the bottom of which there are pumping units.

The pumping units are installed on metal pedestals. The pedestals have a fastening unit with a tight gasket for feeding waste water under pressure to the pressure pipeline. There are guiding pipes for lifting and lowering pumping units, if needed during maintenance. 

When turning on the working pump the waste water runs down the suction pipeline to the distribution chamber. In the chamber there are gate valves that allow to guide the waste water to the discharge pipelines. 

During КНС-АММА normal operation, all the gate valves in the pipelines are open. 

The check valve installed in the pipeline of every pumping unit does not let the waste water get back into the pipeline of the backup pumping unit.

All the gate valves are closed only when check valves are under repair or when failures in the system are being eliminated.

The trash collection basket is designed to collect large wastes that can enter the suction tank with waste water through the feeding pipeline and damage the submersible pumping units.

In the upper part of KNS there is a lid with a hatch. This allows access for the maintenance personnel to the inside of the KNS-АММА. If needed, it allows to take the pumping unit out down the guiding columns using a chain. It allows to take the trash basket out in order to empty it.

There is a ladder to descend down the KNS-АММА.

In the top part there is a ventilation branch pipe for air exchange within the KNS-АММА.

In the side wall of the suction tank there are four universal floating sensors. 

Using the specified sensors the pumping units' operation is controlled automatically.

Our company manufactures sewage pumping stations. The quality of КНС-АММА is acknowledged with certificates of conformance.
