Neptune Series 500 Metering Pumps
Neptune Hydraulically Actuated “dia-Pumps”
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.
EZE-CLEAN Valves–Cartridges can be removed for cleaning without disturbing the piping to the pump.
All Neptune “dia-Pumps” are adjustable from 10% through 100% of capacity by micrometer dial.
Neptune “dia-Pumps” are available in the following materials of construction:
• Cast Iron with 316SS Trim
• 316SS • PVC • Alloy 20 • Kynar
