ASF NewJet DC Pump — 1600 GPH Controllable Submersible Return/Utility Pump

Overview

The ASF NewJet DC 1600 GPH is a high-output, ultra-quiet controllable DC pump engineered for reef, freshwater, and planted aquariums. With precise speed control, feed pause, and soft-start ramping, it’s ideal as a main return on larger systems or as a powerful, efficient feed for reactors and UV units.

Key Features

• Up to 1600 GPH max flow (actual flow depends on head height and plumbing)

• External DC controller with multiple speed steps for fine tuning

• Feed mode (temporary pause) to keep food in-tank during feeding

• Soft-start reduces splash and plumbing shock

• Very quiet, low-vibration operation for living spaces

• Energy-efficient DC motor designed for continuous 24/7 duty

• Marine & freshwater safe

• Submersible installation with vibration-damping suction base

• Stepped barbed outlet for easy tubing connection

Use Cases

• Primary return pump for midsize to larger sumps/AIO systems

• Dedicated feed for carbon/GFO/biopellet/UV reactors

• Circulation for frag tanks and quarantine systems

• Mixing stations and water features

Installation & Maintenance

1. Rinse pump and fittings before first use.

2. Mount fully submerged in sump or display; ensure stable water level at the intake.

3. Attach flexible tubing to the stepped barbed outlet; secure with a clamp if needed.

4. Set speed with the controller; confirm overflow balance and sump return chamber stability.

5. Monthly (or as needed): Unplug, remove front cover, pull impeller, and rinse the impeller/cavity to clear biofilm and debris.
