(2) The maximum discharge pressure is achieved using 150 PSI (10.3 BAR) air/gas supply pressure. Even though the pumps are designed to operate over their entire stroke rate and length ranges, we suggest that you take into consideration your future flow requirements. Rather than operating...

PLUNGER MATERIAL SELECTION The materials available vary in hardness and chemical compatibility. We offer three materials based on our many years of industry experience with various chemicals. Hardness is a key property when selecting the proper plunger material. Our experience has shown that the harder plunger materials not only provide longer plunger life, they also provide greater seal life. A hard plunger is a must when pumping a chemical that is prone to crystallization or if the chemical is contaminated. Of course both of the above conditions will affect seal life. Below is a table that...
