Best efficiency point (BEP) logic
Best efficiency point (BEP) diagram
Example of BEP (best efficiency point)

BlueLinQ Pro has built-in BEP (best efficiency point) control logic functionality. BEP is the point at which the pump operates at peak efficiency. At this point, flow enters and leaves the pump with a minimum amount of flow separation, turbulence and other losses.

Operating the pump closer to its BEP will result in less stress and wear, which increases the reliability and life span of the pump.

At start up, the BlueLinQ Pro will run a number of capacity-contra-run-frequency calculations to determine the optimum frequency to operate the pumps. This test cycle repeats with a pre-set time interval.

Added value when controlling the pump based on BEP control logic:

  • Lower running costs
  • Less hydraulic loads on mechanical components
  • Less stress on bearing and shaft vibrations
  • Less audible noise
  • Less suction recirculation (this also reduces the risk of the pump clogging)
Expansion modules

System expansion can be achieved simply by adding digital and analog IO modules.

Plug and play modules for BlueLinQ Pro:

  • BlueLinQ DI-12: 12 isolated digital inputs with configurable logic
  • BlueLinQ DO-8: This module expands the capacity of the pump controller with an additional 8 digital outputs with configurable logic
  • BlueLinQ AI-6: Up to 6 analog inputs
  • BlueLinQ TI-6: 2 or 3 wire connection to PT100 sensors
  • BlueLinQ AO-6: 6 analog outputs
  • BlueLinQ LI-6: 6 analog inputs for connecting to leak detection sensors on the pumps and mixers

Combined or separate alarms can be set up.

  • 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.

  • 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.
