とするウオーターポンプ。 An impeller installed in the fluid side housing of the pump head is connected to the tip of a rotary shaft inserted from inside the atmosphere side housing of the aircraft body to drive the impeller to rotate, and the fluid side housing of the pump head and the atmosphere side housing of the aircraft body are connected to each other. In a water pump that is sealed by a mechanical seal that is always biased toward the atmosphere-side housing side of the body by a coil spring on the periphery of the rotating shaft between the The mechanical seal is made movable and can be moved in the direction of increasing the spring load of the mechanical seal by the thrust load due to rotation during operation, and can be moved in the direction of decreasing the spring load of the mechanical seal by the biasing force of the coil spring when the operation is stopped. A water pump that is characterized by:
