Pump Solutions Group Neptune Metering Pumps Series- 500

Variable Oil By-pass™ stroke adjustment 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. Features • Simplex capacities from 1 gph (3.7 lph) to 18 gph (68 lph) • Pressures to 1100 psi (77 kg/cm2)
