Abstract

ABSTRACT

The pump is one of the most important parts of the water treatment process at the Regional Water Company (PDAM), which serves as a transfer fluid with the use of very broad, particularly as a means of fluid transfer liquid (water). Induction motors are commonly used in the world Industry is asynchronous induction motor (asynchronous). On the Water Treatment Plant (IPA), there are three transfer pump motor units, two units of the pump motor operates with hours of operation 2×24 hours and one motor pump is in standby mode, with a supply voltage of 400 Volt pump motor has a power transfer commencing 232.24 kW with cos φ 0.99, hydraulic power (pump) 114.48 kW, measured current 339 A, 232.2 kW shaft power pump, water flow 935 m³ / h or 259.7 liters / s for a single unit with a pump motor efficiency of 49.29% with a total of 45.103 m head loss, the raw water through a pipe transfer dipompokan along 800 meters with a diameter of 700 mm and 500 mm
