摘要： PROBLEM TO BE SOLVED: To provide horizontal shaft pump equipment capable of suppressing starting current of an electric motor serving as a driving machine, completing a water filling process in a short time, and allowing a draining operation at an early stage, by reducing a starting torque in starting a pump to start the pump with a low torque.SOLUTION: A suction-type horizontal shaft pump equipment includes a mixed flow main pump or an axial flow main pump and sucks up water by sucking air by a vacuum pump 9 with evacuation piping arranged through the interior of a pump casing 2. Suction piping 8 is connected to an upper portion of the pump casing 2 at the upstream side of a main pump impeller 3. A swirl flow prevention mechanism for preventing a gas-liquid two-phase flow from swirling in starting the main pump and a gas-liquid separation mechanism 15 for separating gas from the gas-liquid two-phase flow are provided at a connecting position of the suction piping 8. The gas separated by the gas-liquid separation mechanism 15 is sucked by the vacuum pump 9 through the suction piping 8.
