   In 1933 Mads Clausen (1905–1966) founded Dansk Køleautomatik- og Apparatfabrik, later in 1946 the company name was changed to Danfoss.The first product was an expansion valve for refrigeration units, it was developed after studying imported valves from the US.

3. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...

4. Diaphragm pump - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_pump

   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 ...

   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).

6. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   A small, electrically powered pump 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 or pneumatic energy.

7. Total dynamic head - Wikipedia

   en.wikipedia.org/wiki/Total_dynamic_head

   In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.

8. Affinity laws - Wikipedia

   en.wikipedia.org/wiki/Affinity_laws

   The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...

   en.wikipedia.org/wiki/Blake_and_Knowles_Steam...

   George Blake was the owner of a brickyard in Medford who developed pumps for removing water from brickyard clay pits. Establishing a pump factory in Boston in 1864, he moved to this site in 1886. In 1879 he entered into a financial arrangement with Lucius Knowles, another pump manufacturer, and their two businesses were formally merged in 1897.
