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.
In a recently released white paper, Wilden pump engineer Carl Glauber pointed out that, since its introduction about six decades ago, AODD pump technology has gained a reputation for outperforming other positive-displacement pump styles in demanding liquid-transfer applications because the design characteristics of AODD pumps enable them to run dry, maintain a suction lift
up to 30 ft (9 m), withstand deadhead conditions without damage, operate while completely submerged, and pass solids up to 1-3/8 in.
Servicing the extensive mine dewatering applications, the new PP108C24 design delivers both great flows and greater heads than its PP108C18 predecessor, without reducing the available suction lift
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
In calculating the total pressure, it is the summation of suction lift
, discharge elevation, friction loss and discharge pressure.
