Three rotary lobe pumps manufactured by Börger are currently playing a significant role in detoxifying oil which has escaped into the water at a decontamination plant used disaster relief agencies and fire services.
The process involves all three pumps in individual stages. First, a self-priming portable Börger Feed pump drives in the contaminated medium and transports it to the plant. This pump is included in a Euro mesh frame and, with the advantage of a built-in frequency, the converter can feed at controlled speeds.
Following the automatic parting of water and the oil, a second Börger Rotary Lobe pump transports the separated, extremely viscous oil into a tanker channel. A third larger Börger pump sends any water containing oil back to the contaminated water for complete detoxification.
With the trinity of Börger pumps, the decontamination mill can detoxify up to 160,000 liters of oil/water mix in 1 hour.
Water is used for balancing purposes to maintain ships. Once a vessel has been released of its cargo, ballast water is tapped to respective tanks. The water is moved back to the sea after the boat is filled up again. Ballast pumps perform this.
In comparison with centrifugal pumps, Börger Pumps have the benefit of being capable of filling and release tanks by merely shifting the direction of rotation. No added control units are required. The rotary lobe pump is competent and self-priming. The pumps are frequency-regulated for more precise balancing the boat. The pump installation is carried out as an ATEX standard.
A Finnish firm that has specialized in systems for waste dumping on ships has been using Börger rotary lobe pumps to carry food waste on boats. The Börger pumps are utilized in a vacuum system that takes only kitchen waste. Meanwhile, over 40 units are in service. The food waste is stuffed to a hopper in the commercial kitchen. Because of the rotation of the rotors, the rotary lobe pump creates a vacuum and consumes the food trash from the commercial kitchen into a storage bin. When in port, the Börger pump is employed to clear the storage box.
Elimination Of Residues
A shipping firm uses Börger pumps on its own 3 oil product tankers for draining the pipe systems. The pumps are not susceptible to dry operating self-priming and can deal with pressures and replacing pumped media without difficulties. As the pumps are fitted on the deck, an explosion-proof layout was needed. The customer is delighted with the high fidelity and the excellent suction behavior of the Börger pumps.
A multi-function vessel run by the Federal Waterways and Shipping Administration is used for collecting and laying icebreaking, light buoys, firefighting, emergency towage, and boat traffic monitoring but also functions as a spillage incident vessel. To this end, the boat with a length of 78.91 m is outfitted with two skimmer arms, which -- in the event of accidents -- can absorb the oil/seawater mix from the water surface. Then oil is separated from the seawater in the onboard separation system. This separation process is used for treating bilge water. For this, a Börger rotary lobe pump carries the bilge into the detachment tank.
Oil Recovery Vessel
Over time, oil spill emergencies frequently occur on the oceans doing notable damage to the atmosphere. Skimmer pumps communicate the oil/seawater mix into the onboard separation system. For this pumping task, it's necessary to use high-performance, reliable pumps. From1996, Börger rotary lobe pumps have been utilized as skimmer pumps on an oil recovery vessel. The pumps constructed and have been configured individually for the application demands. The pump shell was made from stainless steel because of the aggressive salt water.
A severe problem when battling oil spill emergencies is the limited capacity on the oil recovery vessels of these tanks. To utilize the tank capacity as efficiently as possible, the oil recovery vessel is outfitted with its own separation unit. A Börger lobe pump takes the oil out of the water surface of the collecting tank into the oil storage tank. The separated water could be discharged to the sea. The Börger oil pump has been installed on the vessel in 1996 and continues to be conveying the crude oil without any problems since then.
A shipyard looked for a skimmer pump to get an oil recovery vessel that could meet with the increased demands. Based on the continuous positive experience with Börger products on other ships, the Börger rotary lobe pump has been taken into concern. The capacities of the Börger rotary lobe pump when pumping extremely viscous oil and seawater compounds were tested and validated. Additional requirements were the temporary suction of air (dry run), the flow rate of foreign bodies (e.g., dead birds), in addition to a potential change of the direction of rotation.
To fix wind turbines or working platforms on the broad seas, suction piles are used frequently, which can function as a base. The piles often made of steel have a cylindrical shape and are open on one side. With the open side facing downwards, the suction piles are absorbed into the seabed because of the production of vacuity and then hermetically sealed. To make this vacuum, the seawater is pumped out of the suction pile. Two Börger pumps have been fixed on a submersible module and driven by a hydraulic motor. To improve the resistance of the pump casing into the aggressive seawater, the Black Protection surface treatment has been developed by Börger.
On 01 January 2013, the Annex V of the MARPOL convention for the avoidance of pollution by garbage from ships entered into force. According to the annex, the release of all the trash into the sea is prohibited. Commingled food wastes capable of passing through a screen with openings no larger than 25 mm could be discharged into the sea under certain conditions. For macerating the food trash, the user applies a Börger Multicrusher Ocean placed in a 90° tended position. At the top opening, the kitchen garbage is filled through a hopper. A unique "tamping arm" is used to nourish the solids to be macerated completely.
The unproblematic pumping slurp procedure, the short-term dry-run ability, and the gentle pumping almost without emulsification are the purpose why Börger pumps are the perfect pumps for any oil spill crises. The aluminum pump with the 7.3 kW combustion engine is created as a mobile device for use as a portable skimmer pump. This way, completely independent control even in rough terrain is feasible. The flow speed can be varied and adapted to the different conditions using the pump rate.
Sea Water / Waste Water / Bilge
A shipping department had numerous vessels with pumps on hand vehicles. Due to the delicate passages on board, the carts needed special features that could accommodate different pumps to the varying pumped medium. The client was impressed with the reliability and the reduced maintenance costs.
Sea Water With Crude Oil
A coastguard ship is furnished with Börger pumps to manage damage in the case of an environmental catastrophe by priming oil spills in the sea surface. The water/oil compound is split on board, and the clean water is fed back into the sea. Downtime in a crisis is out of the question, and the pumps need to be reversible and resistant to seawater.
Human Waste With Sea Water
A shipyard determined on Börger pumps for the disposal of human waste on board. Their advantages: compact design, low weight, ease of maintenance, and a high level of security with the pressure control unit. The lethal mix of seawater and human waste need a stainless steel liner liquid pump.
The vessel of a disposal corporation for ship-produced trash was outfitted with a Börger Rotary Lobe Pump with the variable-speed device to dispose of debris from large ships. Oil, bilge and seawater subject the matter to excessive wear, nonetheless the simplicity of reliability/dependability and maintenance of the Börger Rotary Lobe Pumps confirm their perfection.
Next time you have a contaminated water issue consider researching the Börger pumps.
