  • Pump impeller technology against blockages
    September 15, 2020
    Pump blockage is a growing and costly issue for wastewater companies. Choosing a pump designed specifically to meet the challenges of frontline operation in sewage networks can dramatically cut downtime and minimize asset lifetime costs.

  • XFP pump with Contrablock hydraulics limits clogging
    The Pernes Les Fontaines wastewater treatment plant in France, part of the Rhône-Ventoux mixed water union, treats a daily pollution of 12’000 population equivalents.

  • Sulzer Pumps reduce downtime at water utility
    Winslow Township is the largest town in Camden County, NJ, USA. The town runs its own in-house water and sewer utility. The pumps installed in the two pumps stations - Ivy Hall and Victoria Manor - often clogged and experienced reliability issues. Even partially clogged pumps greatly reduce energy efficiency. Customer callout time and overtime to service these stations was very high.

  • Sulzer delivers pumps for the largest water construction project in Europe
    As part of the reconstruction of the Emscher river and its tributaries, a multistory underground facility is being built in Gelsenkirchen at the river Hüller Bach. This project comprises three reservoirs, two rainwater treatment plants and three pumping stations. The excavation has a diameter of around 33 meters. Numerous and sometimes very large pumps are needed because of the large quantities of water. Sulzer delivered the submersible pumps for the plant that is expected to be operational in 2020.

  • Submersible pumps run at optimum hydraulic efficiency
    To reduce the carbon footprint, the Avebe wastewater treatment plant in Netherlands replaced their existing radial pumps by Sulzer’s stainless steel XFP submersible sewage pumps with Contrablock Plus impellers and Premium Efficiency IE3 motors.

  • Installation of submersible sewage pumps gives substantial energy savings
    The village Sluis in the Netherlands is a popular touristic attraction and therefore the municipality cannot afford any blockages in the wastewater transportations. The installation of Sulzer submersible sewage pumps gave substantial energy savings.

  • Proven expertise in dewatering pumps rental
    Neptune is a company specialized in the rental and sale of pumping equipment for clean water, wastewater and water loaded to industry, construction and communities. Its rental fleet includes 90% of dewatering pumps and 10% of sewage pumps. Neptune has already trusted Sulzer as a supplier for many years and has ordered several dewatering and sewage pumps.

  • Sulzer’s submersible sewage pump offers unmatched blockage resistance
    Kaimai Valley Services in New Zealand had a pump station that was blocked with soft solids, rags, etc. on average 1-2 times per week. The pump was replaced by a Sulzer submersible sewage pump type ABS XFP and the blockages stopped.

  • Sulzer technology upgrades oldest filter station in Warsaw
    The Warsaw Water Filters in Poland is the oldest water filter station in Warsaw and delivers 50% of the clean water for Warsaw. The upgrade with Sulzer’s XFP submersible sewage pumps resulted in significant energy savings.

  • Sulzer pumps improve wastewater treatment in a sugar and bioethanol plant
    Tereos is the leading sugar and alcohol producer in the Czech Republic. The factory trusts Sulzer’s equipment for its demanding wastewater applications, like the XFP sewage pumps with Contrablock Plus impellers and Premium Efficiency IE3 motors.

  • Sulzer secures contract for Danish climate protection scheme
    Nine Sulzer pumps are set to play a key role in new flood defenses around the town of Ringkøbing. Danish water utility Ringkøbing-Skjern Forsyning A/S has selected Sulzer as the primary pump supplier for a major flood defense project.

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

  • 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.

  • 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.

  • 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.

  • Dewatering in tunneling
    A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.
