suction lift

suction lift

[′sək·shən ‚lift]
(mechanical engineering)
The head, in feet, that a pump must provide on the inlet side to raise the liquid from the supply well to the level of the pump. Also known as suction head.

Centrifugal setups often require a booster pump and a second pump to achieve flow conditions such as a suction lift or when both a high flow and high pressure are required.
This is due to their design characteristics that allow them to self-prime, run dry, maintain suction lift up to 30 feet (9 meters or 14.7 psia), withstand deadhead pumping conditions, operate while completely submerged and pass solids up to 3 inches (76 mm) in diameter.
The full-stroke design provides increased displacement per stroke, resulting in higher productivity for enhanced flow rates and 115 percent greater suction lift. This operational efficiency allows for fewer strokes for the same performance, which reduces energy consumption and extends diaphragm life.
The practical suction lift limit for self-priming pumps is around 26 feet of liquid under ideal conditions.
Commenting on the extension to the MasoSine SPS range, Andrew Ashton, UK Sales Manager at VVMPG said: "MasoSine offers exceptional batch transfer performance, ease of use and suction lift capability for products as diverse as soft fruit and savoury pie fillings, as well as highly viscous products.
The Goulds instruction book was for a Model 3796, size 4x4-10 with a suction lift of eight feet nominal.
For reliability, it features a minimum 100,000 B10 bearing life design and a high-efficiency, low NPSHr impeller especially designed to maintain a good suction lift in bypass applications.
Other benefits include the capability to self-prime with suction lift, a huge variety of seal options, low shear rates, maximum displacement for efficient operation, long-service life and integral relief valve protection on most designs.
Force to overcome all the inlet pressure drops through piping, fittings, filters and strainers must be supplied by atmospheric pressure head, as must the suction lift [Z.sub.0].
In calculating the total pressure, it is the summation of suction lift, discharge elevation, friction loss and discharge pressure.
