Nordberg's distinctive design of diesel pancake engine, used for pumping. The company was founded by Bruno V. Nordberg and Jacob Elias Friend in 1886 in Milwaukee. Nordberg had previously been working at steam engine and sawmill maker E. P. Allis & Co. [2] Friend became the company's president, [3] and later his son, Robert E. Friend, was president and chief executive officer.
The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]
A molecular drag pump is a type of vacuum pump that utilizes the drag of air molecules against a rotating surface. [1] The most common sub-type is the Holweck pump, which contains a rotating cylinder with spiral grooves which direct the gas from the high vacuum side of the pump to the low vacuum side of the pump.

A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa), [2] [3] petrol pumps (in Commonwealth countries), or gas pumps (in North America).
A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [ 1 ] [ 2 ] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface.
An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
