Specific speed N s, is used to characterize turbomachinery speed. [1] Common commercial and industrial practices use dimensioned versions which are of equal utility. Specific speed is most commonly used in pump applications to define the suction specific speed —a quasi non-dimensional number that categorizes pump impellers as to their type and proportions.
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 ...
HMD Pumps in England invents and engineers the world's first magnet drive pump. 1957—Sundstrand develops the first water injection pump for the commercial jet aircraft industry. The pump is designed to boost engine thrust during takeoff. 1962—Sundstrand develops the first Sundyne high-speed centrifugal pump and sells it to Shell Chemical.
The peristaltic pump was first patented in the United States by Rufus Porter and J. D. Bradley in 1855 (U.S. Patent number 12753) [2] as a well pump, and later by Eugene Allen in 1881 (U.S. Patent number 249285) [3] for blood transfusions.
Simple hand-operated reciprocating pump. The simplest example is the bicycle pump, which is used ubiquitously to inflate bicycle tires and various types of sporting balls. [1] Power-operated deep well reciprocating pump; By mechanism. Single-acting reciprocating pump consists of a piston of which only one side engages the fluid being displaced. [2]
[2]: 80 The V-2 rocket design used hydrogen peroxide decomposed through a Walter steam generator to power the uncontrolled turbopump [2]: 81 produced at the Heinkel plant at Jenbach, [3] so V-2 turbopumps and combustion chamber were tested and matched to prevent the pump from overpressurizing the chamber. [2]: 172 The first engine fired ...
Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...
