According to the study, solar pumps, which have made their senior year. But the performance was very little. I have taken them to improve the performance newly found we could reduce the friction of the motor shaft by changing the shaft coupling and shaft are larger than necessary. Change the size of a shaft bearings attached to the motor that we already have. And we can reduce the capacity of the pump can be reduced to 7.5 mm, which is the second stroke this would result in a decreased power consumption. Was reduced to 12.16%, and made a Pump Curve to reciporcating pump
