Hydra-Brake® absorbs power by a combination of pumping and shearing
action with acceleration and deceleration of the water as it passes
through the brake. Rotors and stators are designed to provide
excellent stability, and the performance of the brake is the same in
either direction of rotation. Power absorbed at any given speed may
be varied by increasing or decreasing the water level in the brake.
This can be accomplished by changing the inlet water flow and
adjusting the discharge valve to maintain the desired outlet water
