ASF NewJet DC Pump — 570 GPH Controllable Submersible Return/Utility Pump

Overview

The ASF NewJet DC 570 GPH is a compact, ultra-quiet controllable DC pump for reef, freshwater, and planted aquariums.

• DC controller with multiple speed steps for fine tuning

• Feed mode (temporary pause) to keep food in the tank while you feed

• Soft-start ramp reduces splashing and stress on plumbing

• Very quiet operation with low vibration

• Energy-efficient DC motor designed for 24/7 use

• Saltwater & freshwater safe

• Submersible installation with suction-cup base for stability

Installation & Maintenance

1. Rinse the pump and fittings before first use.

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