Self-Pressurizing Liquid Nitrogen Pump for Liquid Nitrogen Container

This product relies on the operator squeezing the suction bulb by hand (Model ZYB-5) or pressing the foot-operated cylinder (Model ZYB-8) to vaporize a small amount of the liquid nitrogen stored inside the liquid nitrogen container. Due to the high gas-to-liquid volume ratio of liquid nitrogen, the vaporized nitrogen gas pressurizes the liquid nitrogen inside the sealed container, forcing the liquid nitrogen to be discharged from the container for replenishing other containers. It features convenient and reliable operation, along with the advantage of low evaporation loss of liquid nitrogen during the dispensing process.
