500-S Series

500-S Series Hydraulic Metering Pumps come standard in Neptune’s Simplex design, but can be converted to Neptune’s Duplex design - 500-D Series. Neptune’s Duplex design is configured to include two micrometer dials with two liquid heads.

LIQUID HEAD MATERIALS OF CONSTRUCTION

• 316SS
• C-20
• PVC
• PVDF

DIAPHRAGMS

• PTFE

CAPACITY

• 80 gph (3.03 L/h) to 34 gph (128 L/h)

MAX PRESSURE

• 3,000 psi (206.8 bar)

MAX TEMPERATURE

• 316SS - 200°F (93°C)
• C-20 - 200°F (93°C)
• PVC - 125°F (52°C)
• PVDF - 125°F (52°C)

STANDARD MOTOR

• 1/3HP-1ph-115VAC-60c-TEFC

Features and Benefits

• EZE-CLEAN™ Valves – feature cartridges that can be removed for cleaning without disturbing the piping to the pump
• Ten turn micrometer dial calibrated in 1% increments, with the ability to adjust capacity from 10% to 100%
• Variable Oil By-Pass™ Stroke Adjustment provides a better valve performance when compared to variable linkage designs
• 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
• Totally enclosed fan-cooled motor with built-in automatic thermal overload
