Product Overview

The CO₂ low-temperature filling pump is a high-efficiency pumping device specifically designed for the filling and transfer of liquid carbon dioxide. It is widely used in breweries, alcohol production facilities, as well as in pharmaceutical, food, and chemical industries. The pump features a vertical single-plunger reciprocating structure, composed of a liquid cylinder, drive mechanism, safety valve, buffer chamber, and power section. Its compact design, combined with low power consumption and low noise characteristics, ensures stable and reliable performance under low-temperature and cryogenic conditions.

Working Principle

The pump operates using a vertical single-plunger reciprocating mechanism to achieve precise filling and delivery of liquid CO₂. The liquid cylinder accommodates the cryogenic medium, while the drive mechanism powers the plunger’s reciprocating motion. The buffer chamber and safety valve maintain smooth flow and safe system pressure. Low-temperature-resistant materials and specialized sealing enable the pump to function reliably in environments from -50°C to -10°C. The pump can also handle liquid nitrogen and other cryogenic solvents.
