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.
Introduced to the market on June 8, 2009, the Multi-Stage CR-H provides a retrofit option for industrial users of traditional ANSI pumps.
In the Solution to Pump Challenge #3, we touched on efficiency and energy savings by approximating energy costs. Can we do this more precisely?
Several years ago, a golf course community wanted to adorn its entrance with a waterfall.
In Pump Challenge #3 (Pumping Prescriptions, September 2009), the specified parameters for energy estimation were 4,000 gpm and 400 ft.
In Pump Challenge #4, many of you discovered while using the Energy Consumption Evaluator, that the standard listing only goes to 8x6-17 pump size with motor power maxed at 250 hp.
Tests show that solid-body plastic pumps are the best choice for oscillating applications.
If a centrifugal pump is started with the discharge valve open too far and with a low discharge pressure, the liquid in the suction line may accelerate at a rate that causes the suction pressure to drop below vapor pressure.
As energy costs rise and energy efficiency becomes more important in operating pumping systems.
A look at new tool that predicts how pumps and systems interact.
BEP is also the point at which a pump is least prone to failure and its life expectancy is greatest. In other words, it is also a pump's best operating point (BOP).
Cavitation in pumps is a well known but unwelcome phenomenon.
Why do those three affinity laws do such a good job of predicting the performance of a centrifugal pump when its rotational speed or impeller diameter is changed?
