Neptune™ 500 Series Hydraulic Metering Pumps DP-1100-19

Neptune™ 500 Series
Hydraulic Metering Pumps
The Neptune 500 Series hydraulic metering pumps are perfect for metering applications. Each pump features a variable Oil By-Pass™ stroke adjustment mechanism which will allow 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. 500 Series pumps are available in simplex and duplex configurations with capacities up to 94 gallons per hour.
• Ten turn micrometer dial calibrated in 1% increments
• Bright color contrasted dial protected from corrosion by clear PVC covering
• Stroke mechanism moves only when adjustment is made, eliminating wear
• Piston is powered through complete stroke length at all capacity adjustments eliminating stress, wear and shock of lost motion designs
• Standard integrally mounted motors are totally enclosed, fan-cooled, with built-in automatic thermal overload
• Internal relief valve automatically protects the piping and system from overpressure
• EZE-Clean™ valve system allows valve removal for cleaning without disturbing the piping to the pump (Exceptions: 500-E series and 560 series in PVC and PVDF construction)
