The disc pump operates using boundary layer principle and viscous drag with a relatively low efficiency. There are methods to increase head and efficiency, one of them is the placing of blades sector sor splitter blades in disc. This method has been applied only in the low viscosity fluids pumping (v<0.1 stokes). This study describe an experimental rescarch in a hight viscosity fluid (v=2 stokes) with exit angle β2 = 35° and different splitter blades Lengths (Ls) (75, 50, 25%). The prupose is to determinate the splitter blades length that achieves the most effective combination between the blade effect and boundary layer effect in order to increase the energy transmission efficiency from the impeller to the fluid. As result, it can be established that the use of spliter blades is an alternative to increase the performance of the fluid. As result, it can be established that the use of spliter blades is an alternative to increase the performance of the disc pump. The highest efficiency and head were obtained for the gapsize between two disc (b) of 12 mm using a 50% spliter blades length of the man blade length.
