Wave actuated pump apparatus providing paired pump and main floats positionable in horizontally spaced relation on a body by liquid and joined together by an elongated arm having an end rigidly secured to a smaller pump float and an opposite end pivotally attached to the larger main float so that the arm is subject to angular displacement relative to the main float as the floats are displaced vertically with respect to each other in response to wave action in the body of liquid upon which the apparatus floats. A linearly actuatable pump pivotally secured between the arm and the main float pumps a desired fluid in response to the angular displacement of the arm relative to the main float. Operative pairs of the floats, each constituting a pumping unit, are grouped together in proximity to each other and held in such relationship by frame means with the members radiating outwardly in desired angularly spaced relation so that no two pumping units are parallel and hence no more than one pumping unit can be broadside to the travel of the waves at any one time. The pump and main floats are formed to take on water and increase their weight under high or choppy wave conditions, and are formed for automatically releasing the additional water when calmer conditions prevail.
