Auto-pressurized liquid nitrogen pump adopts the physical property, which liquid nitrogen is very easy to vaporize. With a negative pressure suction structure, liquid nitrogen vaporizes fast, which produces ultra-low pressure(≤0.04Mpa) to drain liquid nitrogen automatically from the container. In this case, there are no disadvantages of artificial dumping and volatilizing loss.

Main features:
Small volume and space-saving;
Light in weight, easy to operate and carry;
Boost fast, drain quickly, high efficiency;
Very little liquid nitrogen loss;
Both hand pump and foot pump are available.

This is ideal equipment to withdraw liquid nitrogen from the containers for animal husbandry, medical and scientific research department.
