Reef Octopus VarioS-10 Controllable DC Return Pump (Pressure Rated)

The Reef Octopus VarioS-10 Controllable DC Return Pump (SKU: VarioS-10) represents the absolute pinnacle of high-volume, pressure-rated aquarium circulation engineering distributed by CoralVue. While typical 24-volt DC aquarium pumps easily lose performance when fighting gravity up tall cabinet pipes or pushing through complex filtration manifolds, the VarioS-10 runs on an industrial-tier 36-volt DC power grid. This increased electrical volume allows the brushless motor block to develop immense torque, making it a true pressure-rated circulation engine. Delivering up to 4,226 GPH of water transit and conquering an extreme 29.5-foot maximum vertical head height barrier, this flagship model is built for heavy-duty applications like basement multi-tank systems, dedicated fish-room distribution loops, or driving massive commercial protein skimmers.

Why Buy Your Reef Octopus / CoralVue Product From World Wide Corals:

• We run this equipment ourselves. Reef Octopus skimmers and pumps keep our own coral holding and grow-out systems running — this isn't just a catalog SKU to us.
• Sizing and setup help from people who actually keep corals. Not sure which model fits your tank, sump, or flow needs? Our team can help you choose and set it up correctly the first time.
• Bundle and save. Add your Reef Octopus equipment to your next coral or dry goods order and consolidate shipping — something a standalone equipment retailer can't offer.
• Trusted by hobbyists and public aquariums worldwide.

Support: Need help with setup, programming, or warranty support? Reach out directly to CoralVue Support — the manufacturer's team can walk you through everything from controller setup to troubleshooting.

At the core of the VarioS-10 is absolute system protection and customization. The pump comes bundled with a dedicated smart controller that features a water-resistant membrane touchpad, letting you scroll through 5 distinct preset speed settings to precisely match your overflow draining capacities without using restrictive mechanical ball valves. The controller includes a dedicated 0-10V input port for third-party automation hookups, and a safety float switch jack that allows you to establish an automatic shut-off safety loop if a collection cup fills or a sump section drops too low. Outfitted with an ultra-durable polished ceramic shaft and an internal heat-dissipating housing, the VarioS-10 runs cool and whisper-quiet, bringing heavy commercial fluid dynamics to high-end marine environments.

Key Features

• True Pressure-Rated Impeller Geometry: Features a custom-sculpted closed impellor profile designed to maintain high flow velocities even when working against heavy plumbing backpressure.

• Livestock & Overfill Safety Loops: Direct connection port for an electronic float switch safely cuts off all motor power before a skimmer over-foams or a sump basin runs completely dry.

• Soft-Start Internal Logic: Gradually ramps the motor from zero to your preferred operational speed over several seconds, eliminating damaging pipe hammer and structural line rattling.

• Premium Thermal and Ceramic Components: Utilizes a highly polished structural ceramic shaft and specialized heat-sink tracks to keep the motor running perfectly cool under nonstop, high-amperage usage.

Verified Hardware Configuration

• Suction Input Port Sizing: Features an oversized 50mm (1.5-inch) metric male threaded intake bay to guarantee un-constricted water induction.

• Discharge Output Port Sizing: Formed with a 40mm (1.25-inch) metric male threaded discharge port engineered to handle high-velocity output vectors seamlessly.
