Description
Reef Octopus Water Blaster HY-7000 Water Pump
The Reef Octopus Water Blaster HY-7000 is an ultra-efficient, heavy-duty circulation and return pump designed to move large volumes of water quietly and reliably. Based on the proven motor technology of Reef Octopus skimmer pumps, the Water Blaster series is specifically engineered to deliver high flow with exceptional energy savings and minimal heat transfer into your aquarium.
At the heart of the Water Blaster HY-7000 is an integrated digital control circuit board that manages directional startup, regulates RPM speeds, and provides automatic safety shut-off if an obstruction or dry-run condition is detected. Unlike standard ceramic shafts that attract heavy calcium buildup, the HY-7000 utilizes a Silicon Nitride shaft and bearing system. This ultra-durable material resists calcification and wear, drastically reducing maintenance and ensuring smooth, uninterrupted flow. Designed for maximum plumbing flexibility, the HY-7000 can be operated submersed inside a sump or externally plumbed dry.
Key Features
- High-Efficiency Performance: Delivers up to 1,800 GPH at only 88 watts with minimal thermal transfer to the water column.
- Smart Digital Circuit Board: Controls directional start-up and RPM speeds while offering safety shut-off protection.
- Silicon Nitride Shaft & Bearings: Deters calcium accumulation and offers superior wear resistance compared to standard ceramic components.
- Dual Submersible or External Use: Built for versatile installation, functioning seamlessly wet inside a sump or dry in external plumbing.
- Rotatable Volute & Fittings: Allows flexible plumbing orientations with a 1¼-inch inlet and 1-inch outlet connections.
- Whisper-Quiet Operation: Advanced Neodymium rare-earth magnets ensure smooth, powerful water movement.
Ideal For
- High-volume marine reef aquariums and large freshwater systems requiring reliable return flow.
- In-sump return pump setups or external inline plumbing applications.
- Reef keepers seeking energy-efficient water circulation without elevating tank water temperatures.
- Systems requiring low-maintenance hardware that resists hard-water calcification.
Note: THIS IS NOT A PRESSURE RATED PUMP.This pump is not ideal for second floor applications or to feed Beckett or downdraft skimmers where consistent pressure is necessary.
