Abstract


Coil pump is considered one of non-conventional water pumping devices which use non-conventional energy sources. It is a self supporting system for pumping water. The performance of coil pump under different operating parameters is the main objective concerned of the present study. The parameters considered are submerged ratios, rotational speed and number of coils of the wrapped hose. The experimental results showed significant effects on the pump performance due to the variation in submerged ratio Sr and the pump rotational speed as well. The presence of air with water for submerged ratios 0 > Sr > 100% gives the coil pump its pumping action. Increasing the submerged ratio increases the pump flow rate until it reaches its maximum depending on the pump rotational speed, then decreases to zero when the pump is fully immersed. Submerged ratio has a minor effect on the pump maximum static head, it is nearly constant but decreases drastically to zero when the pump submerged ratio reaches 100%. Increasing the pump rotational speed increases water flow rate until it reaches its maximum depending on the working submerged ratio, then the discharge decreases by increasing the rotational speed. Meanwhile slight changes are obtained for the pump static head when the pump rotational speed changes. The number of pump coils is also one of most effective parameters on the coil pump performance. Increasing number of coils increases the pump head while pump discharge is nearly constant. Good agreement is obtained between the present experimental results and theoretical results developed by other investigators.
