Comparing pump efficiency just got a whole lot easier thanks to a new rating system developed by the Hydraulic Institute (HI). For the first time ever, pump specifiers or purchasers can go directly to an online tool where they can compare the numerical efficiency scores of any pump….Read More
Steam traps play a very important role in steam systems. Last week, we discussed how the float portion of a float and thermostatic (F&T) steam trap operates. This week, we will explore the operation of...Read More
In our last blog post, we introduced the PLEV, or Part Load Efficiency Value from Bell and Gossett. This week we look at some selections and how to use PLEV.
PLEV was created to give a weighted average of the pump efficiency for the HVAC and plumbing industry. This new efficiency average gives the engineer or designer an efficiency that is most likely a better representation of the actual...Read More
Heat pumps have them. Air conditioners have them. Even light bulbs have them. And now, for the first time in history, clean water pumps have them too.
We’re talking about efficiency standards, officially issued for pumps by the Department of Energy (DOE) on January 4, 2016. These new pump efficiency standards, which will take effect ...Read More
