Dry installed sewage pump type ABS FR

Clog-free sewage solutions

The FR dry-installed pump enables economical pumping of heavily-polluted sewage and wastewater in municipal and industrial applications. It is ideal for pumping clear water, polluted water, and heavily-polluted sewage in commercial, industrial, and municipal applications.

Applications
  • Inlet pumping station
    Inlet pumping stations are somewhat similar to large terminal pumping stations. Depending on the depth of the incoming sewer, the lifting heads can range from around 2 up to 30 meters. To prevent hydraulic shock loads, which negatively impact the biological process, the stations often make use of variable-speed drives and/or several pumps in parallel.

  • Outlet pumping stations
    Outlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide. Outlet pumping stations may also be needed to compensate for increasing frictional losses in the outgoing pipe at high flows, for example in long sea outfall pipes.

  • Return of activated sludge
    Outlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide.

  • Storm water pumping station
    During heavy rainfall, storm water pumping stations deliver large volumes of water at low head to receiving surface waters or sewers. Having long been a part of flood management, they are increasingly involved in climate adaptation strategies for low-lying coastal cities.

  • Storm water retention tank
    Storm water retention tanks act as a buffer during periods of heavy rainfall. This is increasingly important as areas become more developed, with hard surfaces such as roofs, roads and parking lots that cannot absorb the rainwater. When storm water retention tanks are implemented, gravity or pumps can be utilized to provide a reduced continuous flow into the sewer system. Sulzer expertise makes it possible to avoid peak hydraulic loads and to limit the stresses on existing sewer systems.

  • Terminal pumping station
    Terminal pumping stations receive municipal wastewater from network pumping stations. Installed in dry or wet wells, the pumps forward the medium to a treatment plant for final purification. Due to the lack of screens at most pumping stations, difficult materials such as fibrous sanitary and packaging items are a constant threat to uptime.
