With auto-suction pumps

The design of the pumping station with automatic suction pumps implies that the pumps are placed directly above the intake tank, eliminating the possibility of pumping equipment flooding. The advantage of this type is the location of pumps above the sewage level in a dry hermetic section, allowing preventive and repair work.

Prior the installation of a complete pumping station in its designed position, an excavation pit should be arranged: excavation works, water level reduction, sheet piling of the excavation walls (if necessary) and a concrete slab anchoring the pumping station housing to prevent its floating up under groundwater pressure. After the PS housing has been fixed in the designed position the pump equipment is mounted according to the manufacturer's datasheet and its connection to the electric control panel in accordance with Electrical Installation Regulations is performed as well as the connection of input and output branch pipes of the pump station with the pipelines of the water supply system, and then hydraulic testing of these connections is done. Next backfilling of the pit around the PS is carried out, layer-by-layer, with compaction by vibrating plate. The final stage is commissioning and testing.

To ensure trouble-free operation of the PS electromechanical equipment, it is necessary to systematically observe the readings of the equipment, check the condition of the electrical connections, the fixing of the equipment, the proper functioning of the earthing system of all the equipment, and perform periodic maintenance of the pumping equipment. Care and maintenance of pump units must be carried out in accordance with the pump unit manufacturer's instructions. When starting up the pump units after repairs, if the pump cable has been disconnected from the control panel, the direction of motor rotation must be checked.
