Has a function to drain boiler filler water from the dearator process to the steam drum through the HP heater and the Lp Heater. To find out the work performance of the BFPT PLTU Suralaya PGU by calculating the head suction and discharge, head total, fluid flow rate and the efficiency of the BFPT. What affects the performance of the BFPT is by keeping the turbine working optimally, and keeping the pump power so that the incoming fluid flow is constant. And perform scale maintenance of pumps, motors and coolant fluids. Efficiency calculations are needed to determine how much the efficiency value of a pump is. Based on the data, the efficiency value before is 68.98%, 70.00% and afterwards 72.01%, 73.50% for BFPT A and for BFPT B 69.31%, 71.10% and afterward 72.05%, 74.20% tend to be To increase. It can be concluded that the effect of discharge affects BFPT performance to decrease and the smaller the head the higher the efficiency.} }
