Backflow pumping station - RP10

Backflow pumping stations reliably prevent wastewater from flowing back into buildings through the sewer system during flooding, heavy rainfall, or blocked pipelines.

Due to climate change and the increasing frequency of heavy rain events, backflow pumping stations are now a key component of modern wastewater systems. If the wastewater can no longer drain by gravity, an integrated motorized backflow valve closes the outlet pipe. Two wastewater pumps then lift the accumulating wastewater via a pressure pipeline into the sewer network.

Shaft body (PP polypropylene), coupling base / fittings (grey cast iron, EN-GJL-250 / ductile cast iron), access ladder (GRP plastic), piping, guide tube, lifting chain (stainless steel AISI 316).

For the disposal of wastewater containing fecal matter using grinder pumps of the GRP 16–50 series or using channel impeller or vortex impeller pumps TP30–50.

Modular shaft system for installation depths of 2–5 m, consisting of: a buoyancy-secured pump station made of PP with DN 100 through-piping and an overflow connection for backflow relief, a DN 100 backflow valve with motor (IP68) and 230 V control unit, two DN 100 pipes for cabling or aeration and a discharge pipe (PE63 or PE75). High resistance to fats, oils, hydrogen sulfide, and almost all chemicals. Permanently watertight thanks to the Safety-Lock seal and load-decoupled shaft element gasket.

Main features are:

• Pumpstation for quick and cost-effective installation with backflow protection, fittings, and piping. Installation depths from 2 to 5m.

• Modular system design. Cone, shaft rings, and shaft base can be combined to suit virtually any installation situation.

• Integrated access ladder in accordance with occupational safety authority requirements.

• Guide rails and coupling bases for easy installation and removal of the pumps under water.

• Approved by the German Institute for Building Technology (DIBt) in accordance with approval Z-42.1-400 and standards EN 13476, Part 3 – Type B, and SN EN 476, with a smooth inner surface and profiled outer surface.
