A pump is a device that moves fluids, or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy.
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller, a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.
A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream. As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Vapor compression chillers may use any of a number of different types of compressors. Most common today are the hermetic scroll, semi-hermetic screw, or centrifugal compressors. The condensing side of the chiller can be either air or water cooled. Even when liquid cooled, the chiller is often cooled by an induced or forced draft cooling tower. Absorption and adsorption chillers require a heat source to function.
Steam power developed slowly over a period of several hundred years, progressing through expensive and fairly limited devices in the early 17th century, to useful pumps for mining in 1700, and then to Watt's improved steam engine designs in the late 18th century. It is these later designs, introduced just when the need for practical power was growing due to the Industrial Revolution, that truly made steam power commonplace.
An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow.
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.
The Weir Group plc is a Scottish multinational engineering company headquartered in Glasgow, Scotland. It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
Gwynnes Limited was a City of London England engineering business, iron founders and pump makers founded in 1849 to capitalise on the centrifugal pump invented by James Gwynne (1804–1850). In 1856 his eldest son, James Eglinton Anderson Gwynne (1832–1915), of Essex Street Wharves on the south side of The Strand was awarded a patent for the manufacture of carbon or charcoal powder. Their Strand site became part of the Victoria Embankment built between 1865 and 1867 and Gwynne profited from judicious investment in the reclaimed land. Their Crisp Road, Hammersmith Ironworks and works at Church Wharf, Chiswick, London, were established in 1867 to specialise in the manufacture of these centrifugal pumps and pumping engines This machinery was for use in practically all purposes where large or small quantities of liquid were required to be lifted and dealt with for low or high heads. A limited liability company was formed in May 1897 to own the business.
The Flowserve Corporation is an American multinational corporation and one of the largest suppliers of industrial and environmental machinery such as pumps, valves, end face mechanical seals, automation, and services to the power, oil, gas, chemical and other industries. Headquartered in Irving, Texas, a suburb of Dallas, Flowserve has over 18,000 employees in more than 55 countries. Flowserve sells products and offers aftermarket services to engineering and construction firms, original equipment manufacturers, distributors and end users. The Flowserve brand name originated in 1997 with a merger of BW/IP and Durco International.
A portable engine is an engine, either a steam engine or an internal combustion engine, that sits in one place while operating, but is portable and thus can be easily moved from one work site to another. Mounted on wheels or skids, it is either towed to the work site or moves there via self-propulsion.
Wilo SE is a European manufacturer of pumps and pump systems for the building technology, water and industrial sectors with headquarters in Dortmund, Germany.

An electric fire engine is a fire engine that is powered by an electric motor—essentially, an electric vehicle designed and used for firefighting. Electric fire engines were first proposed in the 19th century to replace the steam pumpers used for firefighting. The electric motor was claimed to be simpler, cleaner, and faster in operation, would save money, and require less maintenance than the steam fire engine. Though production of most electric-powered fire engines ended in the early 20th century when they were superseded by diesel-powered fire engines, they have seen a revival in the 21st century, with fire engine manufacturers such as Rosenbauer and Pierce Manufacturing designing their own electric fire engines.
Stuart Turner Ltd is a British engineering company, based in Henley-on-Thames, Oxfordshire, England, founded by engineer Sidney Marmaduke Stuart Turner in 1906.
