This research is designed to Design and construction of non-electric water pump equipment in the aquarium beautiful. And test the efficiency of the device. Designed and built. PVC pipe fittings The diameter is 12 inches high 130 centimeters. The operation of the device using the vacuum. Discharge of water and continuous access to equipment. Experimental results Non-electric water pump in the aquarium beautiful. Average water flow rate is 20 liters / hour.

The sensitivity analysis in efficiency of solar water heater system self-circulated by a stream power was performed in this study. The mathematical model of the system was developed based on the experimental results to predict the available amount of water pumped temperature and pressure in main devices. This system was operated by using a simple flat plate solar collector with an exposed area of 1.58 m2 and a storage tank of 30 liters. The results of systematic performance which performed by math model was compared to the experimental results. It was found that the values of were 5.876% 3.583% and 1.361% for vapor pressure and temperature in the flat plate solar collector and temperature in the storage tank respectively. The system was workable when the solar energy input values were equal to or greater than 584 W/m2 607 W/m2 632 W/m2 and 662 W/m2 for discharge head 1 m 1.5 m 2 m and 2.5 m respectively. From system simulation the system could have the daily average thermal efficiency was between 2.94 – 11.47% and the daily average pump efficiency 0.00057 – 0.0026% depending on the intensity of incident solar radiation and the discharge head of the system.
