56-535: The locality, named after the engineer August Borsig , was first settled in 1899 and, on 1 October 1920, incorporated into Berlin with the Greater Berlin Act . Part of Wittenau as a simple Ortslage , Borsigwalde became the 11th locality of Reinickendorf (and the 96th of Berlin) on 24 April 2012, following a decision by the boroughs assembly of 14 March. The decision was announced in the official gazette on 18 May 2012. Located in north of Berlin and in

112-430: A centrifugal pump . The fluid enters along the axis or center, is accelerated by the impeller and exits at right angles to the shaft (radially); an example is the centrifugal fan , which is commonly used to implement a vacuum cleaner . Another type of radial-flow pump is a vortex pump. The liquid in them moves in tangential direction around the working wheel. The conversion from the mechanical energy of motor into

168-464: A curved spiral wound around of thickness half x , though in reality it is manufactured in a single casting. This shaft fits inside a heavy-duty rubber sleeve, of wall thickness also typically x . As the shaft rotates, the rotor gradually forces fluid up the rubber sleeve. Such pumps can develop very high pressure at low volumes. Named after the Roots brothers who invented it, this lobe pump displaces

224-555: A dining room and a bath with swimming pool. Borsig had become sufficiently important by the end of the 1840s that he was able to weather the economic crisis of 1848-1852 with little damage. Starting 1851, foreign railway companies also began to order Borsig locomotives, among them the Warsaw-Vienna Railway and the Seeländische Eisenbahn . After the 500th locomotive had been completed in 1854, Borsig

280-591: A former suburb of Berlin. The works was inaugurated in 1898. The Tegel works area was one of the most modern facilities in Germany at that time. It had its own harbour where the ships brought the material for the locomotives. The works itself had long road with every production step at its place. The end of this production lane was the BORSIG Gate. The brand new locomotives left the works through this gate. The company also developed new products that are still part of

336-530: A gentle pumping process ideal for transporting shear-sensitive media. Devised in China as chain pumps over 1000 years ago, these pumps can be made from very simple materials: A rope, a wheel and a pipe are sufficient to make a simple rope pump. Rope pump efficiency has been studied by grassroots organizations and the techniques for making and running them have been continuously improved. Impulse pumps use pressure created by gas (usually air). In some impulse pumps

392-425: A higher hydraulic-head and lower flow-rate. The device uses the water hammer effect to develop pressure that lifts a portion of the input water that powers the pump to a point higher than where the water started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower, and a need for pumping water to a destination higher in elevation than the source. In this situation,

448-518: A myriad of markets across the world. Triplex pumps with shorter lifetimes are commonplace to the home user. A person who uses a home pressure washer for 10 hours a year may be satisfied with a pump that lasts 100 hours between rebuilds. Industrial-grade or continuous duty triplex pumps on the other end of the quality spectrum may run for as much as 2,080 hours a year. The oil and gas drilling industry uses massive semi-trailer-transported triplex pumps called mud pumps to pump drilling mud , which cools

504-574: A pulsation damper. The increase in moving parts and crankshaft load is one drawback. Car washes often use these triplex-style plunger pumps (perhaps without pulsation dampers). In 1968, William Bruggeman reduced the size of the triplex pump and increased the lifespan so that car washes could use equipment with smaller footprints. Durable high-pressure seals, low-pressure seals and oil seals, hardened crankshafts, hardened connecting rods, thick ceramic plungers and heavier duty ball and roller bearings improve reliability in triplex pumps. Triplex pumps now are in

560-477: A return line back to the suction line or supply tank, provides increased safety . A positive-displacement pump can be further classified according to the mechanism used to move the fluid: These pumps move fluid using a rotating mechanism that creates a vacuum that captures and draws in the liquid. Advantages: Rotary pumps are very efficient because they can handle highly viscous fluids with higher flow rates as viscosity increases. Drawbacks: The nature of

616-414: A slight increase in internal leakage as the pressure increases prevents a truly constant flow rate. A positive-displacement pump must not operate against a closed valve on the discharge side of the pump, because it has no shutoff head like centrifugal pumps. A positive-displacement pump operating against a closed discharge valve continues to produce flow and the pressure in the discharge line increases until

672-493: A total of 16,352 locomotives was built in 1954. The rest of the company went to Rheinmetall. After World War II, the company was called Borsig AG, owned by Rheinmetall (as Rheinmetall-Borsig) and later by VIAG , a company owned by the German Federal Republic. In 1970, Borsig was sold to the private company Deutsche Babcock AG, later known as Babcock Borsig AG. In July 2002, Borsig had to reorganize due to

728-535: A two-axle front pivoted bogie and an extra dead axle behind the only drive axle. On 21 July 1840, Borsig let it compete against a Stephenson -built locomotive on the Berlin-Jüterbog railroad . The Borsig locomotive won by 10 minutes, proving that in spite of the lack of experience, Germans could build locomotives that were at least as good as the British models, and so the import of locomotives and engineers

784-425: Is a more complicated type of rotary pump that uses two or three screws with opposing thread — e.g., one screw turns clockwise and the other counterclockwise. The screws are mounted on parallel shafts that often have gears that mesh so the shafts turn together and everything stays in place. In some cases the driven screw drives the secondary screw, without gears, often using the fluid to limit abrasion. The screws turn on

840-400: Is a type of positive-displacement pump. It contains fluid within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A number of rollers , shoes , or wipers attached to a rotor compress the flexible tube. As the rotor turns, the part of the tube under compression closes (or occludes ), forcing the fluid through the tube. Additionally, when

896-506: Is based on a translation of the German article August Borsig , which cites the following references: Steam pump A pump is a device that moves fluids ( liquids or gases ), or sometimes slurries , by mechanical action, typically converted from electrical energy into hydraulic energy. Mechanical pumps serve in a wide range of applications such as pumping water from wells , aquarium filtering , pond filtering and aeration , in

952-659: Is crossed by the S-Bahn line S25 , and Eichborndamm station serves the locality. August Borsig Johann Karl Friedrich August Borsig ( German pronunciation: [ˈjoːhan ˈkaʁl ˈfʁiːdʁɪç ˈʔaʊɡʊst ˈbɔʁzɪç] ; 23 June 1804 – 6 July 1854) was a German businessman who founded the Borsig-Werke factory. Borsig was born in Breslau ( Wrocław ), the son of cuirassier and carpenter foreman Johann George Borsig. After learning his father's trade, he first attended

1008-414: Is how they operate under closed valve conditions. Positive-displacement pumps physically displace fluid, so closing a valve downstream of a positive-displacement pump produces a continual pressure build up that can cause mechanical failure of pipeline or pump. Dynamic pumps differ in that they can be safely operated under closed valve conditions (for short periods of time). Such a pump is also referred to as

1064-435: Is passed through it. This causes an electromagnetic force that moves the liquid. Applications include pumping molten solder in many wave soldering machines, pumping liquid-metal coolant, and magnetohydrodynamic drive . A positive-displacement pump makes a fluid move by trapping a fixed amount and forcing (displacing) that trapped volume into the discharge pipe. Some positive-displacement pumps use an expanding cavity on

1120-497: Is sometimes used in developing new types of mechanical pumps. Mechanical pumps may be submerged in the fluid they are pumping or be placed external to the fluid. Pumps can be classified by their method of displacement into electromagnetic pumps , positive-displacement pumps , impulse pumps , velocity pumps , gravity pumps , steam pumps and valveless pumps . There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps. In centrifugal pumps

1176-402: Is the simplest form of rotary positive-displacement pumps. It consists of two meshed gears that rotate in a closely fitted casing. The tooth spaces trap fluid and force it around the outer periphery. The fluid does not travel back on the meshed part, because the teeth mesh closely in the center. Gear pumps see wide use in car engine oil pumps and in various hydraulic power packs . A screw pump

1232-537: The Feuerland ) near the Oranienburger Tor , neighboring his old company's factory, and founded his own machine factory, focusing on locomotives . The founding date was declared to be 22 July 1837, the day of the first successful casting in the foundry. Despite tremendous costs, the first locomotive, bearing factory number 1 and the name BORSIG, was finished in 1840. This locomotive had an interior frame,

1288-626: The Berliner Stadtschloss (Berlin City Palace). The company was expanding rapidly in those years, since new railways were being built all over Germany. In 1847, construction of the new Moabit ironworks started and they became operational in 1849. The machine factory and iron foundry in Kirchstraße was bought in 1850, and this put the total number of employees at the three Berlin factories at 1800, making Borsig's company one of

1344-715: The Königliche Provinzial-Kunst- und Bauschule (Royal Provincial Art and Building school), then until fall of 1825 the Königliche Gewerbe-Institut (Royal Institute of Trade). He received his practical training in engine construction at the Neue Berliner Eisengießerei (New Iron Foundry of Berlin) of F. A. Egells, where one of his first tasks was the assembly of a steam engine in Waldenburg , Silesia. After

1400-480: The artificial heart and penile prosthesis . When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a multi-stage pump . Terms such as two-stage or double-stage may be used to specifically describe the number of stages. A pump that does not fit this description is simply a single-stage pump in contrast. In biology, many different types of chemical and biomechanical pumps have evolved ; biomimicry

1456-405: The car industry for water-cooling and fuel injection , in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry , pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular

1512-539: The potential energy of flow comes by means of multiple whirls, which are excited by the impeller in the working channel of the pump. Generally, a radial-flow pump operates at higher pressures and lower flow rates than an axial- or a mixed-flow pump. These are also referred to as all-fluid pumps . The fluid is pushed outward or inward to move fluid axially. They operate at much lower pressures and higher flow rates than radial-flow (centrifugal) pumps. Axial-flow pumps cannot be run up to speed without special precaution. If at

1568-427: The current manufacturing program: pressure vessels and compressors. The Great Depression made an end the success of BORSIG as a private company. By 1930, the company was on the verge of liquidation , the locomotive business was saved by a merger with AEG . Borsig built a number of famous locomotives, among which was the world speed record holder DRG Class 05 , the first steam locomotive to hit 200 km/h. The last of

1624-525: The death of August Borsig, the company was led and expanded by his son August Julius Albert Borsig . On the occasion of the completion of the 1000th locomotive, a large celebration with many prominent guests was held, among them the explorer Alexander von Humboldt . At this time, the company that had started out with 50 workers, had 2800 employees. It continued its expansion, and moved some part of its production to Zabrze in Silesia in 1862. In 1872, Borsig

1680-686: The desired direction. In order for suction to take place, the pump must first pull the plunger in an outward motion to decrease pressure in the chamber. Once the plunger pushes back, it will increase the chamber pressure and the inward pressure of the plunger will then open the discharge valve and release the fluid into the delivery pipe at constant flow rate and increased pressure. Pumps in this category range from simplex , with one cylinder, to in some cases quad (four) cylinders, or more. Many reciprocating-type pumps are duplex (two) or triplex (three) cylinder. They can be either single-acting with suction during one direction of piston motion and discharge on

1736-407: The direction of flow of the fluid changes by ninety degrees as it flows over an impeller, while in axial flow pumps the direction of flow is unchanged. An electromagnetic pump is a pump that moves liquid metal , molten salt , brine , or other electrically conductive liquid using electromagnetism . A magnetic field is set at right angles to the direction the liquid moves in, and a current

1792-478: The drill bit and carries the cuttings back to the surface. Drillers use triplex or even quintuplex pumps to inject water and solvents deep into shale in the extraction process called fracking . Typically run on electricity compressed air, these pumps are relatively inexpensive and can perform a wide variety of duties, from pumping air into an aquarium , to liquids through a filter press . Double-diaphragm pumps can handle viscous fluids and abrasive materials with

1848-446: The fluid trapped between two long helical rotors, each fitted into the other when perpendicular at 90°, rotating inside a triangular shaped sealing line configuration, both at the point of suction and at the point of discharge. This design produces a continuous flow with equal volume and no vortex. It can work at low pulsation rates, and offers gentle performance that some applications require. Applications include: A peristaltic pump

1904-423: The gas trapped in the liquid (usually water), is released and accumulated somewhere in the pump, creating a pressure that can push part of the liquid upwards. Conventional impulse pumps include: Instead of a gas accumulation and releasing cycle, the pressure can be created by burning of hydrocarbons. Such combustion driven pumps directly transmit the impulse from a combustion event through the actuation membrane to

1960-410: The head of the cylinder. In the suction stroke, the plunger retracts and the suction valves open causing suction of fluid into the cylinder. In the forward stroke, the plunger pushes the liquid out of the discharge valve. Efficiency and common problems: With only one cylinder in plunger pumps, the fluid flow varies between maximum flow when the plunger moves through the middle positions, and zero flow when

2016-535: The insolvency of its parent company, Babcock Borsig AG, Oberhausen. In 2004, Borsig bought ZM Zwickauer Maschinenfabrik, a manufacturer of reciprocating compressors and blowers, today known as BORSIG ZM Compression GmbH, situated in Meerane/Saxony. In 2006, Borsig bought the industrial boiler manufacturer DIM KWE, today BORSIG Boiler Systems GmbH. Today the BORSIG Group consists of six companies: In 2008

2072-416: The large-scale enterprises of its time. The increasing number of orders also increased Borsig's private wealth, and he soon became a rich entrepreneur who was not averse to splendor and a patron for many artists. August Borsig was said to be a strict but just boss with a zest for action. For his workers, he set up a sickness fund, a funeral expense fund, and a savings bank. His company had an instruction room,

2128-418: The line bursts, the pump is severely damaged, or both. A relief or safety valve on the discharge side of the positive-displacement pump is therefore necessary. The relief valve can be internal or external. The pump manufacturer normally has the option to supply internal relief or safety valves. The internal valve is usually used only as a safety precaution. An external relief valve in the discharge line, with

2184-524: The middle of Reinickendorf, Borsigwalde borders with the localities of Tegel (west and south), Reinickendorf (southeast) and Wittenau (north and east). It is not too far from the Lake Tegel and on its north-eastern corner is located the Reinickendorf town hall . Borsigwalde is less than 1 km from Berlin-Tegel Airport and is linked to it by the A 111 motorway . The border with Tegel

2240-647: The name Borsig is connected with locomotives to this day. By 1843, railway companies in Prussia had ordered 18 locomotives, and in 1844, Borsig could exhibit his 24th locomotive at the Berlin industrial fair. The one hundredth locomotive was finished in 1846. Meanwhile, Borsig built the steam pump for the fountain at Sanssouci and participated in the building of the domes of the Nicolai Church in Potsdam and

2296-678: The other, or double-acting with suction and discharge in both directions. The pumps can be powered manually, by air or steam, or by a belt driven by an engine. This type of pump was used extensively in the 19th century—in the early days of steam propulsion—as boiler feed water pumps. Now reciprocating pumps typically pump highly viscous fluids like concrete and heavy oils, and serve in special applications that demand low flow rates against high resistance. Reciprocating hand pumps were widely used to pump water from wells. Common bicycle pumps and foot pumps for inflation use reciprocating action. These positive-displacement pumps have an expanding cavity on

2352-480: The plunger is at the end positions. A lot of energy is wasted when the fluid is accelerated in the piping system. Vibration and water hammer may be a serious problem. In general, the problems are compensated for by using two or more cylinders not working in phase with each other. Centrifugal pumps are also susceptible to water hammer. Surge analysis , a specialized study, helps evaluate this risk in such systems. Triplex plunger pumps use three plungers, which reduces

2408-404: The pulsation relative to single reciprocating plunger pumps. Adding a pulsation dampener on the pump outlet can further smooth the pump ripple , or ripple graph of a pump transducer. The dynamic relationship of the high-pressure fluid and plunger generally requires high-quality plunger seals. Plunger pumps with a larger number of plungers have the benefit of increased flow, or smoother flow without

2464-475: The pump fluid. In order to allow this direct transmission, the pump needs to be almost entirely made of an elastomer (e.g. silicone rubber ). Hence, the combustion causes the membrane to expand and thereby pumps the fluid out of the adjacent pumping chamber. The first combustion-driven soft pump was developed by ETH Zurich. A hydraulic ram is a water pump powered by hydropower. It takes in water at relatively low pressure and high flow-rate and outputs water at

2520-469: The pump into the discharge pipe. This conversion of kinetic energy to pressure is explained by the First law of thermodynamics , or more specifically by Bernoulli's principle . Dynamic pumps can be further subdivided according to the means in which the velocity gain is achieved. These types of pumps have a number of characteristics: A practical difference between dynamic and positive-displacement pumps

2576-513: The pump requires very close clearances between the rotating pump and the outer edge, making it rotate at a slow, steady speed. If rotary pumps are operated at high speeds, the fluids cause erosion, which eventually causes enlarged clearances that liquid can pass through, which reduces efficiency. Rotary positive-displacement pumps fall into five main types: Reciprocating pumps move the fluid using one or more oscillating pistons, plungers, or membranes (diaphragms), while valves restrict fluid motion to

2632-404: The ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. Rotodynamic pumps (or dynamic pumps) are a type of velocity pump in which kinetic energy is added to the fluid by increasing the flow velocity. This increase in energy is converted to a gain in potential energy (pressure) when the velocity is reduced prior to or as the flow exits

2688-421: The shafts and drive fluid through the pump. As with other forms of rotary pumps, the clearance between moving parts and the pump's casing is minimal. Widely used for pumping difficult materials, such as sewage sludge contaminated with large particles, a progressing cavity pump consists of a helical rotor, about ten times as long as its width. This can be visualized as a central core of diameter x with, typically,

2744-416: The successful completion of this task, Borsig was made factory manager for eight years. In 1828, he married Louise Pahl; they had one son, Albert. From early on, Borsig was a supporter of railroads. Despite the lack of experience with railroads in Germany and the risks involved in the founding of a railroad machinery manufacturing company, Borsig used his savings to buy a site in Berlin at Chausseestraße (in

2800-488: The suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant through each cycle of operation. Positive-displacement pumps, unlike centrifugal , can theoretically produce the same flow at a given rotational speed no matter what the discharge pressure. Thus, positive-displacement pumps are constant flow machines . However,

2856-469: The suction side and a decreasing cavity on the discharge side. Liquid flows into the pumps as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant given each cycle of operation and the pump's volumetric efficiency can be achieved through routine maintenance and inspection of its valves. Typical reciprocating pumps are: The positive-displacement principle applies in these pumps: This

2912-399: The tube opens to its natural state after the passing of the cam it draws ( restitution ) fluid into the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract . Plunger pumps are reciprocating positive-displacement pumps. These consist of a cylinder with a reciprocating plunger. The suction and discharge valves are mounted in

2968-756: The whole BORSIG Group got a new owner, the KNM Group Berhad, Kuala Lumpur, Malaysia. The actual product and service programme of the BORSIG Group consists of pressure vessels, heat exchangers, process gas waste heat recovery systems, quench coolers, scraped surface exchangers, reciprocating compressors for process gases, turbo compressors for process gases, reciprocating compressors for CNG filling stations, blowers and blowers systems, compressor valves, membrane technologies, such as emission control units, vapour recovery systems, gas conditioning, advanced separations, industrial boilers, power plant engineering, power plant services and industrial services.

This allowed him to tighten his monopoly position, and 67 of the 68 new Prussian locomotives in 1854 came from Borsig factories. Some years earlier, his magnificent villa in Berlin- Moabit had been completed, fulfilling a dream of Borsig's. However, he could not enjoy his wealth for very long. He died in Berlin on 6 July 1854, at the height of his power. After

A further six machines of this type were sold to the Berlin-Stettiner Eisenbahn and the Oberschlesische Eisenbahn in 1842. In the beginning, the Borsig company also built steam engines for their own needs and machines for other companies as well as cast parts for art and construction. However, the focus soon shifted to locomotive building, and

Albert Borsig co-founded the Maschinenfabrik Deutschland on the Köln-Mindener Eisenbahn line in Dortmund but the most successful chapter in the Borsig business history ended with Albert's death in 1878. The company continued to be led mostly by Borsig family members and continued to build large numbers of locomotives, but it began to lose market share to other traffic-related companies. The company moved to Tegel,
