Quiet, energy-efficient, multi-function pumps

The Impulse is a quiet, energy-efficient, multi-function pump. It is ideal for fresh and saltwater aquariums, protein skimmers, indoor fountains, water-cooling and all similar submersible and inline applications which require energy efficient, ultra quiet performance. The Impulse is equipped with a synchronous motor and an advanced impeller, ceramic shaft and bearings (stainless steel on the Impulse 400), and an adjustable flow rate. Multi-size hose adapter fittings and suction cups are included.


Wet/Submerged Application

Impulse Pumps can be used for a variety of fully submerged applications including aquariums, sumps, and outdoor or indoor ponds.

Dry/Inline Application

They can also be used for dry or inline applications including skimmers, reactors, and sumps. Use one of the included multi-size hose adapter fittings for quick and easy connections.

Flow Regulation

Use flow regulation to adjust the flow to the ideal rate for your particular application. Adjustments up to 400, 600, and 800 GPH respectively.

Wear-Resistant Impeller

The Impulse is equipped with a synchronous motor, advanced impeller, and ceramic shaft and bearings.


Head Ratings

Pump head measures the vertical distance a pump can effectively move water. As the height increases, water pressure decreases because the water must travel a longer distance. Measure the distance water will travel on your setup (e.g. the distance between your sump and aquarium) to determine the right Impulse for you.
