Grundfos (Danish pronunciation: [ˈkʁɔnfʌs]) is the largest pump manufacturer in the world, based in Denmark, with more than 19,000 employees globally.. The annual production of more than 16 million pump units, circulator pumps (UP), submersible pumps (SP), and centrifugal pumps (CR).
The oil pressure generated in most engines should be about 10 psi per every 1000 revolutions per minute (rpm), peaking around 55-65 psi. [ 2 ] Local pressure (at the crankshaft journal and bearing) is far higher than the 50, 60 psi &c. set by the pump's relief valve, and will reach hundreds of psi.
Its bulk modulus at 1000 °F (538 °C) is 310,000 psi (2.14 GPa), higher than of a hydraulic oil at room temperature. Its lubricity is poor, so positive-displacement pumps are unsuitable and centrifugal pumps have to be used.
An automatic lubrication system consists of a reservoir with a pump, feed lines, metering valves, and injectors. The automatic lubrication system is connected to a control system via switchs.
