Home to the largest contiguous cotton-growing region in the world and encompassing more than 115 square miles, Lubbock is the economic, education and health care hub of the South Plains of Texas.
In the Solution to Pump Challenge #3, we touched on efficiency and energy savings by approximating energy costs. Can we do this more precisely?
In Pump Challenge #3 (Pumping Prescriptions, September 2009), the specified parameters for energy estimation were 4,000 gpm and 400 ft.
Enterprising biosolids pump manufacturers are finding abundant new opportunities in the biosolids segment.
This article explores the use of condition monitoring at the UPM-Kymmene's Wisaforest pulp and paper mill in Finland. Production capacity is 800,000 air dried tons per annum (ADt/a) of pulp and 180,000 ADt/a of kraft and sack papers.
A critical phase in the design and construction of a pumping station is a witnessed pump performance test at the manufacturer's facility.
Initial costs and life cycle costs affect which sealing method is chosen for an application.
What is the definition of specific speed, to what does it pertain and how is it used?
Municipal wastewater treatment plants continue to adopt submerged membrane bioreactor (MBR) technology due to two advantages
Rotary pumps are positive displacement pumps that use rotational, rather than reciprocating, motion during their pumping cycle. They can be designed to pump liquids, solids, gases or mixtures of all three.
In the past, there were two ways to seal a pump: the mechanical seal method or the compression packing set. Either choice was subject to potential leakage and/or hidden costs. For compression packing users, pump leakage has become so widely accepted that many companies have focused on better ways to divert the leakage rather than eliminate the leaks.
In 1982, Richard Dubner of Chevron developed a graph for use in establishing minimum continuous flow rates for centrifugal pumps.
Infrastructure is in the headlines again thanks to the Obama Administration and its strategy to help create jobs by rebuilding the nation's roads, bridges and water systems.
Water system operators know the challenges of keeping municipal drinking water consistently and safely chlorinated. Increased safety concerns regarding common disinfectants and mandated chlorine residual targets make maintaining large or small water systems difficult.
If any silver linings exist for the economic crisis, one is the heightened public and governmental awareness about the nation's need for infrastructure improvements.
Boiler and Pressure Vessel code contains rules for the design and construction of unfired pressure vessels. The design of bolted flanges requires that gasket constants referred to as m and y be used in the calculation.
