Control cabinet of the sewer pump station (ShU KNS)

Control cabinet of sewage pumping station ShU KNS is designed for automatic and manual control of all mechanisms of sewage pumping stations.

The application of cabinets is possible, as in the new facility construction as well as in the modernization of currently operating stations (in the projects which include cabinets type Sh5101, Sh5914, or similar)

Built-in PLC inside the KNS cabinet allows you to easily adapt to the peculiarities of the specific station.

Start of the main pumps for sewage pumping is provided by soft starter UPP1 series ("soft-starter").

The use of the soft starter and special control algorithms embedded in the programmable controller allows:

  • damping of dynamic operating modes of electric and hydraulic equipment;

  • switch on the redundant to replace the failed pump;

Wiring diagram ShU KNS


ShU KNS allows to control the sewage pumping station that have the following equipment:

  • tank with level sensor of its filling (minimum - level of "dry run", the operating - the levels of activation and deactivation of sewage pumps, maximum - the level of tank overflow);
  • main sewage pumps from tank up to 200 kW (~ 380);
  • hydraulic packing pump and jet break tank with water contact sensor
  • drain sump with level sensor of its filling;
  • drainage pumps;
  • industrial water pumps (pumps hydraulic packing);
  • valve in the input collector with the drive, open sensor, medium and closed positions and torque limit clutch;
  • exhaust ventilation systems that have a primary and backup fans with ability to operate separately and simultaneously;
  • input ventilation systems, which have main and redundant fans with ability to operate separately and simultaneously and operating via radiator with a contact temperature sensor of the input air and output product;
  • system of working and emergency lighting and auxiliary lifting and transport mechanisms with manual control.



  • operating mode selection Auto / Manual and separately for each pump motor;
  • automatic on / off pump motors via the soft starter (UPP) or directly from the Mains in case of UPP failure;
  • emergency level control of receiving tank filling with visual and audio alarm;
  • automatic / manual power supply switching in case of an input failure ;
  • status indication of power supply, pump motors, auxiliary machinery (motors of input ventilation, motors of exhaust ventilation, motors of drainage pumps, lifting and transport mechanism) levels in the receiving tank;
  • motor protection in emergency situations;
  • enabling / disabling of redundant pumps in case of insufficient performance of main pumps via UPP or directly from the mains in case of UPP failure;
  • enabling any sewage transfer pump by the signal from any level sensor in the receiving tank (for the same operating time of pumps)

Optional supply by Customer request: software and software adjustment (to monitor the performance of equipment and control from a remote PC (SCADA - System))
