It is possible to shorten the time precooling, was also losses of low-temperature liquefied gas, foresight pump efficiency is also good, cost to also provide a favorable low-temperature liquefied gas pump. The motor 1 and the impeller 2 is arranged at the same time, the motor (1) and the upper impeller (2) which is connected to the shaft 3 for transmitting the rotational drive between them such that the lower side, the motor ( 1) and between the impeller (2), each to each other present in the low-temperature liquefied gas, the closed space 14 to be introduced in communication, and the motor 1 and the impeller 2, the impeller (2) in the liquid phase of the low-temperature liquefied gas, keeping at the same time so as to present, to form a heat adjuster (11) for holding to the presence of the motor (1) in a gas phase of low-temperature liquefied gas. Thus, the foresight that is do not need to immerse the motor (1) in the liquid it is possible to greatly reduce a precooling time to reduce the evaporation loss of low-temperature liquefied gas, according to it, to configure the motor 1 itself to a relatively inexpensive material can.
