Super Efficient, Dependable with a Green ECO-Cartridge™


AquaMotion's innovative design created a pump line with the lowest power consumption. This is based on actual amp draw comparisons with published Underwriters Laboratories data of comparable PSC motor or ECM pumps on the market. The PSC design features the only field replaceable and field flushable Green ECO-CARTRIDGE™. This cartridge is the heart of every circulator and contains all moving parts. The design allows for replacement of the cartridge or by pulling it apart and flushing it and reinstalling it. This is a tremendous advantage in areas of hard water. The design prevents black iron oxide and contaminants from entering into the cartridge. The flushable cartridge extends the life of the pumps and makes them a sustainable product that can double its operating life.

Our History


About AquaMotion

hans

AquaMotion was created with the vision of designing the most energy efficient, high performance, sustainable circulator line on the market with more benefits and features to meet and exceed customer demands and to compete with the world and US market leaders.

AquaMotion was incorporated in 2002 by Hans Kuster. The Company developed the revolutionary Green ECO-Cartridge™ design which is the heart of every circulator and contains all moving parts. It has the only field replaceable and field serviceable cartridge on the market. Competitive manufacturers have to replace their entire cartridge or pump, increasing the foot print on the environment and doubling the cost to the consumer.  The cartridge design and long life bearings are patented. The design also prevents black iron oxide and contaminants from entering into the cartridge. This PSC pump line offers the lowest power consumption of any PSC motor and the lowest power consumption of any ECM pump.

How did we do it? With the help of the most experienced engineers in the water lubricated pump field. Benno Lebkuchner, formerly Senior VP of Engineering at the market leader in wet rotor circulators joined him at Sparco and then at AquaMotion. Benno and Hans, using their lifetime experience in the hydronic industry began designing the most reliable and energy efficient PSC circulator line.

Michael McNamara joined AquaMotion in 2013 as Director of Engineering. McNamara previously worked as Director of Engineering at Grundfos, Pentair and as VP of Engineering at Taco. McNamara brings experience from these top industry companies.  At AquaMotion he designed many new products, ECM, electronically controlled motor circulators and hot water recirculation valves and systems which keep AquaMotion in front as technology leader in pumps and hot water recirculation systems, including the first outdoor hydronic pump system for tank-less heaters.

Hans Kuster previously was Senior VP at the US market leader in circulators for 21 years. He founded Sparco Inc. of Warwick RI, in 1983, Sparco developed 18 U.S and foreign patents for their products. Sparco became a leading manufacturer of hydronic heating and energy products. They included radiant manifolds, zone valves and the AquaMix proportional water mixing valves. Sparco brand-named his products for the world leader in radiant floor heating, Wirsbo/Uponor, Zurn, Kohler and Grundfos. Hans sold Sparco to Honeywell International in 2000.
