Up to the present, the manufacture of the micro pump generally used MEMS processes to obtain micro scale channels. However, the geometry of the channels, the cost is relatively high due to the characteristics of the most micro fabrication techniques. In this research, we focused on manufacture of valve less pumps in inexpensive approach. The design of the valve less pump consists of four horizontal inlet channels and one vertical outlet channel. The geometry of the channels with minimum width gives great challenges in fabrication and is difficult to be achieved by traditional fabrication techniques. Conventional manufacturing process was used to manufacture the chamber and channels of the pump. SOLID WORKS software was applied to the model and plans the manufacturing sequences. The piezoelectric Actuator was attached to the fabricated valve less pump chamber to test the performance. Four different channel width designs were manufactured successfully and tested at various piezo-triggered frequencies. This research provides a solution to manufacture the Valve less pump geometry inexpensively. Conventional process was proved to be a suitable approach to generate pre-assembled valve less pump structure with channels, and is applicable to other similar applications.
