The Machine de Marly (French pronunciation: [maʃin də maʁli]), also known as the Marly Machine or the Machine of Marly, was a large hydraulic system in Yvelines, France, built in 1684 to pump water from the river Seine and deliver it to the Palace of Versailles. [1] King Louis XIV needed a large water supply for his fountains at Versailles.
Originally, it was one of two steam engines used to pump water back up to the 491-foot (149.7 m) summit level of the BCN Old Main Line (Birmingham Canal) canal at Smethwick, not far from the Soho Foundry where it was made. The other engine, also built by Boulton and Watt, was at the other end of the summit level at Spon Lane. In 1804 a second ...
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. 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 ...
It pumped water from the mine using seven lifts of pumps of 18-and-16-inch (0.46 and 0.41 m) diameter. [17] The 110-foot-tall (34 m) chimney stack for this engine's boilers was completed before the engine house was built. The unique feature of this stack, the vertical letters "EPAL" displayed in white bricks near the top, is still visible.
The technology is simple, typically using a parallel-bar double-cam lift driven from a low-power electric motor, although the number of pumpjacks with stroke lengths 54 inches (1.4 m) and longer being used as water pumps is increasing. A short video recording of such a pump in action can be viewed on YouTube. [6]
The US will honor the late former President Jimmy Carter, who died at age 100 on December 29. President Joe Biden declared January 9 as a day of mourning in an executive order – the same day as ...
Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve.

Buoyed by promised pardons of their brethren for their Jan. 6 crimes and by Trump’s embrace of popular extremist far-right figures, those groups will likely see a resurgence after January ...
