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 the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...
A small submersible AC sump pump with a garden hose connector. A sump pump is a pump used to remove water that has accumulated in a water-collecting sump basin, commonly found in the basements of homes and other buildings, and in other locations where water must be removed, such as construction sites. The water may enter via the perimeter ...
Retired modern submersible Star III of Scripps Institution of Oceanography. A submersible is an underwater vehicle which needs to be transported and supported by a larger watercraft or platform. This distinguishes submersibles from submarines, which are self-supporting and capable of prolonged independent operation at sea.
The Mir submersibles are 7.8 m long, 3.6 m wide, 3.0 m high, and weigh 18,600 kg (maximum payload is 290 kg). The personnel sphere's walls are 5 cm thick, and the inside diameter of the working area is 2.1 m. Three viewports are provided (viewport material is 18 cm thick): the forward-facing port is 20 cm diameter; the two side-facing ports are ...
A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [ 1 ] by mechanical action, typically converted from electrical energy into hydraulic energy. Mechanical pumps serve in a wide range of applications such as pumping water from wells ...
Water aeration. Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms.
The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...
Hand pump. Animation of a suction hand pump. On the up stroke of the piston the foot valve opens and suction brings water into the pump head. On the following down stroke of the piston the valve on the piston opens up and allows water to flow above the piston. On the successive up stroke of the piston water is pushed out of the outlet.
