ASF NewJet DC Pump — 3200 GPH Controllable Submersible Return/Utility Pump

Overview

The ASF NewJet DC 3200 GPH is a high-output, ultra-quiet controllable DC pump for larger reef and freshwater systems. With precise speed control, feed pause, and soft-start ramping, it delivers powerful, efficient flow for main returns, manifolds, and reactor/UV lines while keeping heat and noise low.

Key Features

• Up to 3200 GPH max flow (real-world 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 to reduce splash and plumbing shock

• Very quiet, low-vibration operation

• Energy-efficient DC motor 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 larger sumps/AIO systems

• Drives manifolds powering multiple accessories

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

• High-throughput mixing stations and water features

Installation & Maintenance

1. Rinse pump and fittings before first use.

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

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

4. Use the controller to set speed; confirm overflow balance and return-chamber stability.

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