Abstract

Centrifugal pump is one type of pump that has a very wide scope of use related to the head and the capacity produced. On this occasion the author tries to explain the results of research on the performance of a centrifugal pump if variations in valve opening angle (valve) on a centrifugal pump will produce a head. The valve opening angle is intended to determine the increase in pump performance due to the opening of the valve angle. Adding to the valve opening (pump) is very influential on the flow capacity of the water produced, this will also affect the work of the pump, specific speed, power and pump efficiency. So that the centrifugal pump working point can be obtained with Capacity (Q) 0,000733 m3 / s, Head (H) 7,02 m, Hydraulics (Ph) 50,501 watts, Efficiency ((p) 16,396%, this can implemented if followed by the addition of power from the driving motor.
