A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.
On June 22, 2012, the Jiaolong submersible set a deep-diving record for state-owned vessels when the three-person sub descended 6,963 meters (22,844 ft) into the Pacific Ocean. [ 7 ] Among the most well-known and longest-in-operation submersibles is the deep-submergence research vessel DSV Alvin , which takes 3 people to depths of up to 4,500 ...
Since its first expedition to the Titanic shipwreck in the summer of 2021, the Titan’s crews encountered problems aboard the submersible, including issues with its electrical system and battery ...
In refrigeration systems, subcooling the refrigerant is necessary to ensure the completion of the remaining stages of the refrigeration cycle. The subcooling stage provides certainty that the refrigerant is fully liquid before it reaches the next step on the cycle, the thermal expansion valve , where the presence of gas can be disruptive.

Several different types of pump impellers Flexible impeller of cooling system pump of an outboard engine (1 euro cent coin for comparison, diameter 16.25 mm). An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.
These systems are replaced with liquid circulation pumps and heat exchanger and/or dry cooler systems. Power use at data centers is often measured in terms of power usage effectiveness (PUE). The definitions of PUE for air-cooled devices and liquid immersion cooled devices are different which makes such direct comparisons inaccurate.
