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.
