This invention discloses a high-efficiency dual-condition fluid transfer pump, relating to the field of fluid machinery technology. Addressing the problems of existing fluid pumps being single-function, inefficient, and lacking adaptability to various operating conditions, this invention achieves high-efficiency fluid transfer by optimizing the pump impeller structure and fluid channels, resulting in high transfer efficiency, low energy consumption, and minimal wear. Through a closed internal circulation channel and a throttling adjustment component, the adjustable conversion between mechanical kinetic energy and fluid pressure is achieved. It can be widely applied to various fluid transfer scenarios and various scenarios involving the mutual conversion of mechanical kinetic energy and fluid pressure.

Regarding refillable containers for liquids, the aim is to make it easier to visually confirm the appropriate liquid volume when refilling, thereby preventing overfilling. [Solution] The liquid refill container 100 has a self-standing container body 10 for storing liquid L. The container body 10 has an opening 40 for pouring in liquid, and an indicator part 50 is provided on the inner wall surface 10a of the container body 10 at a position visible from the opening 40 to indicate when the liquid level has been reached. The indicator part 50 is a recess formed in the inner wall surface 10a, or a projection that protrudes from the inner wall surface 10a toward the inner space. The liquid refill container 100 may further include a head part 20 that can be attached to and detached from the mouth 14 of the container body 10, and the head part 20 may include a nozzle 24, a liquid suction tube 23, an actuator 22, and a pump function.
