Leakage control type ABS CA 461

Detect leaks at the first sign

CA 461 is designed to spy and detect leakage in pumps and mixers. The amplifier is housed in a norm enclosure fitted for DIN-rail mounting. The unit is available in two executions, 24 VDC or 110-230 VAC supply.

Leakage relay type ABS CA 461

  • Flooded Area
    Flood control
    Climate change is challenging natural disaster prevention. When water runs off the land in large quantities, Sulzer’s comprehensive range of pumps provide reliable, cost effective and efficient solutions for flood control.
  • Wastewater treatment process - plant head
    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.
  • Wastewater collection process network - pumping stations
    Network pumping station
    Network pumping stations collect municipal wastewater from residential homes and communal schemes. Installed in dry or wet wells, the pumps deliver the effluent to a terminal pumping station. Since most pumping stations are not equipped with screens, the pumps must cope with difficult materials such as fibrous sanitary and packaging items.
  • Wastewater treatment process - outlet pumping station
    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.
  • Wastewater collection process network - storm water pumping stations
    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.
  • Wastewater collection process network - storm water retention tanks
    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.
  • Wastewater collection process network - terminal pumping stations
    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.
