Description

Product Details
  • Capacities up to 432 gpd and pressures to 900 psi
  • PVC and SS materials available

Neptune Series 500-E pumps are designed for long life, precise control and ease of maintenance. The Variable Oil Bypass™ stroke adjustment allows improved valve performance over variable linkage designs. Turndown ratio is 10:1.

All pumps have a 1/3 hp, 1 phase, 115 VAC, 60 Hz, TEFC motor with built-in automatic thermal overload. Series 500-E pumps utilize a hydraulically actuated diaphragm. Pump speed is controlled in 1% increments by a micrometer dial. Under constant conditions, these pumps are rated at +1% accuracy.

Pumps with model numbers ending in "N5" have 1/2" NPT suction and discharge ports, and pump model numbers ending in "N3" have 3/4" NPT suction and 1/2" NPT discharge ports. The motor has a junction box for electrical hook-up. Accessories such as injectors, foot valves and tubing are not included.

Repair kits for either the PVC or SS pumps include suction/discharge valve cartridges, valve seat and valve cap O-rings and diaphragm. Repair kits are sold separately from pumps.

Shipping: Ships motor freight.
