Main design features
CA 462 is designed to spy and detect leakage and temperature 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.

To minimize the risk of false alarms the leakage failure has to be detected for time duration of approximately 10 seconds.

To simplify the mounting the unit is fitted with plug-in type of connectors.

The unit has separate alarm outputs for temperature and leakage.

CA 462 also has main contactor relay output energized depending on alarm/s with manual reset option.

Included in the kit is also a Xylem MiniCas adaptor.

Applications
  • Commercial waste disposal from toilets
    Commercial wastewater from toilets comprises all sewage water flushed from toilets on commercial, industrial or public properties.

  • Commercial wastewater without toilet waste
    Commercial wastewater without toilet waste includes drainage and grey wastewater.

  • Domestic waste disposal from toilets
    Domestic wastewater from toilets comprises all sewage water flushed from toilets or residential properties.

  • Domestic wastewater without toilet waste
    Domestic wastewater without toilet waste includes drainage and gray wastewater.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
