better together POLYETHYLENE LIFTING STATIONS FOR CIVIL AND INDUSTRIAL INSTALLATIONS

better together Polyethylene lifting stations for civil and industrial installations The increasing use of underground spaces, such as toilets, garages and car parks in new urbanisation or building redevelopment projects, often requires the use of systems to collect wastewater and lift it to a higher level. The liftBOX lifting stations are designed to collect rainwater, wastewater or sewage and transfer it to a higher level, which would otherwise be unreachable due to the distance or by gravity, delivering it to the sewage line or the treatment plant. The lifting stations consist of a...

Specifications • Roto-moulded polyethylene tank • Constant, thick walls with horizontal reinforcing ribs • Contoured bottom to prevent stagnation and facilitate positioning of the pump • Rated volume from 650 to 19000 litres • Inlet pipe diameter from DN 125 to DN 400 • Outlet diameter from DN 50 to DN 150 • Optional inlet effluent filter basket (models M and L only) • Valve chamber separate from tank compartment (models M and L only) Advantages over conventional lifting stations with concrete tanks • Lower weight and lower transport costs • Faster installation • Shorter settling and drying...

Separate valve operating chamber Each lifting station can be equipped with a valve chamber with an independent, snap-closing cover. This allows access to the valves without opening the main tank. For each pressure line, the valve chamber comprises a cast-iron knife gate valve complete with handwheel control and a check valve with cast-iron body and full free passage NBR rubber sinking ball. On model L versions, there is an additional knife gate valve for emptying the main manifold in case of maintenance work on the flow line. Optional accessories 1 Fall protection grid Fall protection...

Electronic and electromechanical panels The electric control panel, available separately, are the "brains" of the lifting station. It allows the automatic start-up of the pumps using float switches and the management of any alternation cycles. The installation of the acoustic and/or visual alarm module enables the signalling of any anomalies or malfunctions, such as the risk of overflowing, impeller blockage or water entering the mechanical seal chamber. Standard electronic boards Electronic control panels suitable for managing 1 or 2 single-phase electric pumps with a power rating of 0.37...
