This is a crucial parameter for pump selection and is a popularly used parameter for ascertaining industrial requirements. By eliminating the inlet head, we remove the effect of the supplied pressure to the pump and are left with only the pump’s energy (head) contribution to the fluid flow. Schematic representation of pressure heads in a pump.
Waterous Company is an American manufacturer of fire pumps, hydrants and fire suppression equipment. Based in South St Paul , Minnesota . [ 1 ] Originally part of Waterous Engine Works Co. Ltd , the fire equipment operation in Winnipeg was relocated to St Paul, Minnesota in 1886 [ 2 ] [ 3 ]
A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
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).
Peerless Pump was acquired by FMC Corp. in 1932 and continued to assemble, sell and service pumps out of the Fresno facility. [5] In 1976 FMC Corp. sold Peerless Pump to Indian Head. In 2007, Peerless became a wholly owned subsidiary company of the Grundfos group of Denmark. By that time most operations had been consolidated to other locations.
[3] [4] Under Booker, Godiva Fire Pumps came under Sigmund Pulsometer Pumps Ltd (SPP) – who within a 9-month period also acquired Europump Services Ltd of Bristol and 76% share in Robot Pumpen NV of Holland. [5] In April 1988 Braithwaite Holding Company acquired SPP (and hence Godiva Fire Pumps) for £31 million.
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
