Neptune 500-D Hydraulic Duplex Metering Pumps

About Neptune 500-D Hydraulic Duplex Metering Pumps

500-D Series Hydraulic Metering Pumps are Neptune's Duplex design. Neptune's Duplex design configuration includes a two micrometer dials with two liquid heads. Each pump comes with a variable Oil ByPass™ stroke adjustment feature which allows for better valve performance than variable linkage designs. The valve checks have extra time to seat even with heavy liquids since they are idle during the by-pass part of the suction / discharge strokes. Comes standard with 1/3 HP, 1ph, 115 VAC, 60C TEFC motor with other options available. Materials of construction options include: 316 Stainless Steel, Carpenter-20, PVC or PVDF Liquid Heads & PTFE Diaphragms. FKM standard O-Rings with optional PTFE offered. Capacities range from 0.80 gph (3.03 L/h) to 34 gph (128 L/h). 3,000 psi (206.8 bar) maximum pressure on certain configurations. Maximum Temperatures: 316SS & C-20 - 200°F (93°C); PVC & PVDF- 125°F (52°C).
