The Hydrowizard is an impeller pump designed to move great amounts of water and
create current more efficiently than any other previously developed technology.
Studies and simulations of water movement in nature have led to the evolution of this
unparalleled concept in pump technology.
The combination of mechanical components (impeller/rotor, stators, water entry and exit points) and a newly designed electrical
motor, are perfectly tuned to work together. They allow 200,000 liters (50,000 gallons) of water to flow through each hour, using only
348 Watts of energy.
The designs of the motor and impeller are matched to produce the most efficient output. All materials in the pump are chosen to last
as long as possible. Twin bearings made from SiC ceramics guarantee the smooth running of the rotor. All parts that are affected by
mechanical forces in the pump are made from carbon fiber reinforced plastics, which not only saves overall weight but also helps to
carry heat away from the motor. The only metal parts that come in contact with water are the titanium screws used to hold the casing
around the motor and fix the impeller in place. All materials used are safe for permanent use in marine environments.
The motor and the SiC bearings are not sealed, allowing the water to flow through freely. This prevents mineral deposits on the
bearings and increases the motor’s lifespan.
The unique combination of impeller and stator produce a directional, non-rotating current with a maximum velocity of 3.3 meters per
second (11 feet per second). This allows fish and other animals to swim through the current right up to to the pump without getting
The pump’s intake has a surface four times greater than the exit, with water streaming into the pump at 0.9m/s (3 feet
per second). This allows even very small animals to swim through the intake current without getting pulled into the
pump. The laminar (directional) current is of great help here, allowing most streamlined animals to remain swimming
in this area behind the pump with virtually no effort.
A modern solution to reproduce nature’s water movement
The electric motor runs on just 48 Volts of DC current. Even a break in the cable would not cause any injury to animals or people.
The Hydrowizard can simulate any number of currents and waves through its electronic controller. Short impulses are used to
generate waves, slow changes in current can simulate tides, or very slow changes could simulate seasons of high and low water. Of
course the pump can also generate a constant stream.
The pump has been programmed to self clean the
impeller from built up debris. In Current Mode, the
impeller will stop after one hour, spin backwards
several times and return to the previously
programmed output. In wave mode the impeller
will spin backwards every fifty waves.
The device offers energy savings of (8760 h *
0,348 kW = 3048 kW/h) compared to a
conventional impeller pump with the same output.
(8760 h * 3,5 kW = 30660 kW/h) equals 27612
kW/h annually, at 0,20 Cent/kW/h. This could
result in savings of 5500$ per year. If the pump is
run in wave mode, the energy usage is reduced by
50%. Likewise the energy consumption is lowered
if the pump is running in current mode at less than
full output. Expressed in carbon emissions, the
pump will save 16.5 metric tons of CO2 emissions
per year compared to conventional technology.
