500 Series - Hydraulic Metering Pumps

The Neptune 500 Series hydraulic metering pumps are perfect for metering applications. Each pump features a variable Oil ByPass™ stroke adjustment mechanism which will allow better valve performance than variable linkage designs. The Series 500 Hydraulic Metering Pump is a diaphragm metering pump featuring the EZE-CLEAN valve design with double ball check enabling the valve to be removed without having to disconnect or move piping.

The Series 500 is also leak free and handles a wide range of corrosive, flammable, or hazardous liquids. Because of quality, durable construction, the Series 500 has long term reliability and remains accurate up to 1% for longer. Materials available are 316 SS, PVC, PVDF and Alloy 20. Designed to handle flows up to 97 gallons per hour. Designed to handle pressures up to 3,000 psi and flows up to 97 gph.
