Free Upgraded Shipping!

Sunpole was first brought into the US market by AquaMaxx, and proven that they belong in this world of DC pumps at an affordable price, and are now introducing their new V-Series 0-10V External Controllable DC pumps.

With a long history of making high quality equipment for commercial and industrial application, Sunpole has taken many of these technologies and standards and applied it to the aquarium application. The high quality of the pump can be felt as soon as you take it out of the box!

Universal 0-10V Capable

The new Magnus V-Series features a 0-10V input allowing you to control your pump via external controller - intricately program your pump`s flow throughout the day!

Submersible and External Applications

The V-Series DC pump can be simply dropped into your sump for internal / submersible applications. You can also plumb your AquaMaxx pump externally with the included slip adapters for hard plumbing, or hosebarb for soft.

Closed-Type Impeller

The V-Series DC pump features a closed-type impeller. This design is typically found only on more expensive pumps and features a funnel that helps to focus the water flow and allows the pump to handle higher pressure applications. 

Smart Controller

A versatile controller allows you to adjust water flow from 10% to 100%. Six different selectable speeds lets you control the flow rate to your exacting needs. A convenient Feed Mode button turn off the pump for 10 minutes during feeding. A silicone keypad helps to keep out moisture and offers a rich tactile feel.

High Reliability

With electronic controller components removed from the pump, the V-Series DC pump is ultra reliable. The controller features an electronic driver that is cooled with a built-in heat sink. Certified Mean Well drivers are utilized to ensure durability and dependability.

Superior Quality

Not skimping on materials, the V-Series DC pumps feature rust-proof titanium screws and nuts. Internals of the pump is rated IPX8 waterproof. Pump and controller casing are made with high quality ABS plastics. Rotor shafts and bearings are made of ceramic to maximize efficiency and durability.

Quietness, taken to a whole new level!

The new V-Series DC pumps are tuned to a working frequency of above 20,000Hz. This means that most of the noise generated by the pump is at a frequency higher than what human ears are able to hear.

Testing procedures include putting the pumps through four thermo shock cycles (from 170°F to -4°F), storing the pump at 170°F for 48 hours, storing the pump at -4°F for 48 hours and operating the pump in 120°F water for 72 hours! Withstanding these extreme conditions, the V-Series DC pumps is also one of the toughest and most durable aquarium pumps available!

Manufacturer Info

SUNPOLE is derived from the brushless DC motor technology found in power tools, where the rotor rotates around the axis supported by bearings, similar to planets in the solar system orbiting the sun. This in turn served as inspiration for the brand name. The brand logo consists of six solid circles symbolizing constantly revolving rotors, thereby embodying the imagery of reliability as well as SUNPOLE`s spirit of continuous innovation and the pursuit of quality.

Not worth the money
How could I be the first reviewer? This pump began acting up after a year or ownership. After cleaning ran another 6 months then stopped again. CLeaned again and ran a week then stopped. I can always get it started again but it is completely unreliable
