The first known use of a crankshaft in a chain pump was in one of al-Jazari's saqiya machines. The concept of minimizing intermittent working is also first implied in one of al-Jazari's saqiya chain pumps, which was for the purpose of maximising the efficiency of the saqiya chain pump. Al-Jazari also constructed a water-raising saqiya chain pump which was run by hydropower rather than manual labour, though the Chinese were also using hydropower for chain pumps prior to him. Saqiya machines like the ones he described have been supplying water in Damascus since the 13th century up until modern times,[32] and were in everyday use throughout the medieval Islamic world.[33]Interestingly, the depiction of the chain in al-Jazari's pump appears to be in the form of a Möbius strip, from long before the Möbius strip was first identified as an object of study in mathematics.[34]

Citing the Byzantine siphon used for discharging Greek fire as an inspiration,[35] al-Jazari went on to describe his version of suction pipes, suction pump, double-action pump, and made early uses of valves and a crankshaft-connecting rod mechanism, when he developed a twin-cylinder reciprocating piston suction pump. This pump is driven by a water wheel, which drives, through a system of gears, an oscillating slot-rod to which the rods of two pistons are attached. The pistons work in horizontally opposed cylinders, each provided with valve-operated suction and delivery pipes. The delivery pipes are joined above the centre of the machine to form a single outlet into the irrigation system. This water-raising machine had a direct significance for the development of modern engineering. This pump is remarkable for three reasons:[7][36][37][38]
al-Jazari developed the earliest water supply system to be driven by gears and hydropower, which was built in 13th century Damascus to supply water to its mosques and Bimaristan hospitals. The system had water from a lake turn a scoop-wheel and a system of gears which transported jars of water up to a water channel that led to mosques and hospitals in the city.[40]
ClydeUnion Pumps is the culmination of a long and eventful engineering legacy. Through the highly-respected, ground-breaking core companies from which we originate, we are able to claim a 140-year history. Now we are playing an instrumental role in securing the vital energy and water resources that a sustainable society will rely on in the future.
Our engineered-to-order pumping technology is used to carry out all kinds of critical industrial functions. The vast majority of nuclear power plants currently in operation around the world employ our reactor feed pumps. We are also a valued flow control engineering partner to the oil/gas industry - supporting upstream, downstream, transportation and offshore exploration activities. Other key areas we address include marine applications, seawater desalination and waste water treatment.
Tim Kennelly: Because the plant could not generate any power, the SWP had to purchase additional power on the grid market. Our generation generally goes to help pay for the costs of pumping and moving the water. We were still able to maintain water deliveries because the plant has a bypass gate that allows us to move water from the Thermalito forebay to the Thermalito afterbay. While we were not able to move as much flow as we could have if all four units were in operation, we were still able to maintain water flows to meet the demands of local agriculture, to provide for fish habitat, and to meet other supply needs. 2ff7e9595c
