Dover Corporation is an American conglomerate manufacturer of industrial products. [5] The Downers Grove, Illinois-based company was founded in 1955. [5] [6] As of 2021, Dover's business was divided into five segments: Engineered Products, Clean Energy and Fueling, Imaging & Identification, Pumps & Process Solutions and Climate and Sustainability Technologies.

The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools. Gases (6) are returned to the engine sump. Pressure pump (4) forces the de-gassed and cooled oil (5) back to the engine's lubrication points (7).
Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").
Gear pumps [1] [2] trochoid pumps [3] and vane pumps [a] are all commonly used. Plunger pumps have been used in the past, but these are now only used rarely, for small engines . To avoid the need for priming , the pump is always mounted low-down, either submerged or around the level of the oil in the sump.
In most production automobiles and motorcycles, which use a wet sump system, the oil is collected in a 3 to 10 litres (0.66 to 2.20 imp gal; 0.79 to 2.64 US gal) capacity pan at the base of the engine, known as the sump or oil pan, where it is pumped back up to the bearings by the internal oil pump. A wet sump offers the advantage of a simple ...
It continued to purchase well-known companies involved in manufacturing such things as overhead cranes, gasoline-dispensing pumps, and heavy equipment for mining and construction. [ 6 ] In 1968, the Wayne Oil Tank and Pump Company, established in 1891, [ 7 ] merged with Dresser, [ 8 ] becoming the Dresser-Wayne Company. [ 9 ]
Often though, oil in the sump can slosh during hard cornering, starving the oil pump. For these reasons, racing motorcycles and piston aircraft engines are "dry sumped" using scavenge pumps and a swirl tank to separate oil from air, which is also sucked up by the pumps. [2] A sump can also be found in an aquarium, mainly a reef system.
