NEPTUN ring well pump

Multistage submersible pumps for ring wells. These pumps incorporate a motor cooling jacket, eliminating the need for a fully submerged pump and eliminating the need for a casing pipe, as is required with traditional multistage pumps. NEPTUN series pumps can be installed in conjunction with a hydrophore tank.

Features:
• The pumps feature a cooling jacket, so they do not need to be fully submerged, and there is no need for protective pipes.
• A built-in float protects the pump against dry running.
• Thermal protection built into the motor winding.
• A capacitor built into the motor (no external starter box required); the pump is ready for installation right out of the box.
• Warranty and post-warranty service available.
