If asked, can you say how well your pumps perform?

A pump not equipped with the means to measure flow, pressure or power is inherently inefficient
No Comments
Pumps of all sizes are used throughout the process industries to transfer a wide range of fluids. Along with proper pump selection and installation, it’s also important to have the information on hand needed to protect a pump and operate it efficiently.

How to turn eggshell waste into income

Drying system reduces pathogen risk; residue used as fertilizer or animal-feed mineral additive
No Comments
Each year, an estimated 76 billion eggs are consumed in the United States. Prior to final consumption, about 25 billion of those eggs are first processed into egg products. The egg-processing plants must break those eggs before further processing occurs. In doing so, these plants generate an estimated 600,000 tons of eggshell waste per year.
