At AquaCave, we offer some of the best selection & best prices on submersible water pumps and powerheads for you marine, reef, and freshwater aquarium.
Submersible Aquarium Water Pumps and powerheads are operating while being completely submersed inside aquarium or sump filter. Rather than sucking water through an inlet tube like an external pump, most submersible pumps and powerheads do not have an inlet in which you can attach tubing or hose. They are used primarily to feed protein skimmers and reactors and to provide water movement within the tank.

VorTech Propeller Pump by EcoTech Marine :
Bracketless Design
The VorTech minimizes the intrusion of equipment in your tank by using a patent pending bracketless design; this allows the motor to be on the outside of the aquarium and uses a magnetic field to transfer torque through the aquarium wall to the propeller located in the water.
No Heat added to the water
Due to the use of high intensity metal halide lighting, inefficient return pumps, and powerheads, many aquarists must resort to expensive equipment or loud fans to keep their water temperature stable. The VorTech induces very little heat into the aquarium because of EcoTech Marine's patent pending magnetically coupled design which transfers motion through the glass, but not heat.
Controllable and Versatile
The VorTech uses the most advanced motor technology available, allowing the water flow rate to be completely controllable. Operating on tanks between 20 and 500 gallons and producing between 100 and 3,000 gallons per hour of flow, the VorTech is the most versatile flow product on the market. The VorTech is designed to operate on gap thickness from 1/8" to 3/4".
No AC electricity in the aquarium water
The VorTech is safer than existing products because there is no dangerous AC electricity brought into the aquarium. This keeps your fish and corals happy and healthy, while minimizing your own risk of electrocution.
Run-Safe Design
The VorTech is designed to be the safest and most reliable product on the market: Over-current protection - if the propeller becomes jammed, our microcontroller will sense the problem and shut the motor down to prevent overheating. Magnetic couple protection - if the VorTech becomes separated into two parts during operation, our microcontroller will sense the separation and cut power to the motor.
Energy Savings
The VorTech moves more water within your aquarium than conventional powerheads, plus you save money by not having to invest in and run a costly chiller.
Low Maintenance
The VorTech is virtually maintenance free. Classic powerheads use an impeller attached to a magnet assembly which needs to be cleaned every few months. The VorTech need only be serviced minimally to replace a simple and economical bearing every few years.
Wave Controller Accessory*
The EcoTech Wave Controller will wirelessly control up to 10 VorTech Propeller Pumps with an intuitive user interface while creating optiomal flow using wave motion algorithms.
*Note: Product currently in development
Battery Backup Acessory
An IceCap, Inc. battery backup powers the EcoTech Marine VorTech Propeller Pump for up to 24-hours during a power outage emergency.

Koralia Power Heads by Hydor

Sicce Voyager High Flow Powerheads: The Voyager 2 is the NEW stream pump for marine aquariums, reef aquariums, and fresh water aquariums, with flow rates up to 800 gallons per hour. Thanks to the exclusive magnetic support, it can be positioned anywhere: on the sides, behind the tank, and around the aquariums corners. Its support permits it to reach the widest angulations: up to 180 degrees vertically and 360 degrees circulatory with endless orientation possibilities. The Voyager's versatility in movement and positioning makes it possible to hide it anywhere, always assuring optimal performances. The rotation of the front ring nut allows you to regulate the flow, recreating faithfully the effect of marine currents and satisfying even the most particular of your corals needs. And with the most durable rotor and shaft, the unique bidirectional design of the rotor assures that the pump always starts in the correct sense, avoiding the annoying noises provoked by an inversion of the sense of circulation. The rotor and shaft of the Voyager are wear-resistant beyond compare! Most suction cups applied in a salt water tank become stiff with time, compromising their hold and causing the pump to become instable. The exclusive magnetic support for the Voyager is long-lasting and reliable and is ideal for glasses of 15mm width.

The Voyager can be used in fresh water aquariums. In fact, it can be used to raise the deposits from the bottom of the tank for better filtration, contributing to cleaner and clearer water.

Maximum inclination, flexibility, silence & reliability - all in one unit!

Advantages of Synchronous Motors by Sicce Synchronous motors have the following advantages over non-synchronous motors:
- Speed is independent of the load, providing an adequate field current is applied.
- Accurate control in speed and position using open loop controls is possible.

Their power factor can be adjusted to unity by using a proper field current relative to the load.
A capacitive power factor, (current phase leads voltage phase), can be obtained by increasing this current slightly, which can help achieve a better power factor correction.

- Their construction allows for increased electrical efficiency when a low speed is required.
- Better Performance.
- Higher Head Pressure per watt
- Higher Flow Per Watt
- More efficient
- Maximum energy conservation and lower electric bills
- Quiet Operation below 30db
- Much Smoother Rotation
