The pump is a turbo engine of the most widely used in the present. Pump needs ranging from household, hospital to industrial. In operation, the pump is often unavoidable in the cavitation event at very low suction pressure which can not be tolerated and instability when there is a change in the head characteristic curve in transient operating conditions. The most recent research is being done by various researchers is the concept of counter rotation pump that can overcome the two major pumps problems simultaneously. <br /> <br /> <br /> Counter-rotation pump developed a type of axial pump with two rotating impeller on one axis and the opposite axis direction. Therefore counter-rotation pump design is similar to the usual axial pump design. In a counter-rotation of the pump design was done counting, calculating parameters such as pump-parameter tangential velocity, the relative velocity of the water to the blade, absolute fluid velocity, Cu, Ca, W~, &#946;, &#946;~, head impeller respectively, chord length, the coefficient lift and drag, blade attack angle, Stagger angle blade, the lift and drag force, torque, power and efficiency. <br /> <br /> <br /> Calculation results obtained from the power supplied impeller one blade to the front and rear fluid is 154.55 Watt and 251.7 Watt respectively, impeller efficiency front and rear are 83% and 63% respectively. The results of this pump design should be simulated with the simulation software such as Fluent and conducted analysis axle and chassis construction.
