The R. A. Ross & Associates Story
ESTABLISHED
YEARS EXPERIENCE

EMPLOYEES
“Without pumps, our business shuts down. Pumps are vital to our production line. We pump a chemical that, in the past, would eat up a pump diaphragm. Our Ross associate recommended Aro pumps with stainless steel bodies and a diaphragm designed to withstand the chemicals we use. We manufacture over 250,000 fluorescent lights per year. Ross was a huge help in keeping our plant up and running 24/7. These people know their business.”
