Cryogenic Pump

The cryogenic pump, short for cryogenic liquid pump, is the pump used in oil, air separation and chemical devices for transport of cryogenic liquids (LOX, LN, LAr, LPG, etc.). It moves cryogenic liquid from a low pressure spot to a high pressure one.

With development of air separation, the pump also becomes popular. It plays an irreplaceable role in air separation plant. For example, it is used for liquid circulation and compression. Due to excellent quality and easy maintenance, it is commonly found in metallurgical, chemical, communication, electronics, pharmaceuticals, food, and other fields.

We have a complete range of cryogenic pumps. In 1998, we first developed the cryogenic liquid filling pump. Our business started from the gas cylinder filling pump, CO2 cylinder filling pump and cryogenic submerged pump for LNG. Then we launched the high flow series, five-column series, and centrifugal series. Thus we provide a more comprehensive range of products and services to customers.

We integrate advanced technologies and more than 40 years of manufacturing experience in our design. Now our product pioneers in the performance and diversity. In terms of maintenance and after-sales service, we also take the lead both at home and abroad. The suitable medium gases are O2, N2, H2, CO2 and LNG. The pump types are cylinder filling pump, transfer pump, submersible pump, and process pump. Related spare parts are available for all the above kinds.

The cryogenic pump serves as supporting equipment for air separation unit. It is exported to many Middle Eastern and Asian countries. The 35Mpa high-pressure liquid gas tanker pump is used in military and aerospace industry.
