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.
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 ...
KOS+ M openwell submersible pump. Small-scale sewage pumping is normally done by a submersible pump.. This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.

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.
Typhoon-class submarines feature multiple pressure hulls that simplify internal design [clarification needed] while making the vessel much wider than a normal submarine. In the main body of the sub, two long pressure hulls lie parallel side by side, with a third, shorter pressure hull above and partially between them (which protrudes just below ...
Ultimately, 18 of the submersible’s crew members explored the wreck site for the first time in 2021, the filing stated. Others, such as Paul-Henry Nargeolet, had already traveled to the site.
The units' life-support systems have 246 man-hour capacity, or 3.42 days for a three-person crew. The units are designed for pressure at 6,000 metre depth, and have been tested to 125% of that pressure. In field testing, Mir-1 descended to 6,170 m and Mir-2 descended to 6,120 m.
