 Product Description

Neptune's hydraulically actuated "dia-pumps" have Variable Oil By-pass™ stroke adjustment which allows better valve performance than variable linkage designs. The valve checks have extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and discharge strokes.
