Reliable and Efficient Cryogenic Submerged Pumps for Industrial Applications

Key Features of Cryogenic Submerged Centrifugal Pumps

1. Submerged Design: These pumps operate submerged in the cryogenic liquid they are pumping, which ensures that the pump stays cold and avoids thermal stress caused by fluctuating temperatures.

2. Cryogenic Temperature Handling: These pumps are engineered to handle extremely low temperatures, typically ranging from -160°C to -270°C, depending on the type of cryogenic fluid being pumped.

3. Material Composition: Materials used in these pumps are selected for their ability to withstand low temperatures and prevent brittleness. Common materials include stainless steel, Inconel, and other alloys suited for cryogenic service.

4. Centrifugal Action: They use centrifugal force to move the cryogenic liquid, which is ideal for continuous, high-flow-rate applications. The impeller inside the pump spins rapidly to create a flow of liquid through the system.

5. Sealless Design: To minimize the risk of leakage, many cryogenic pumps are designed without mechanical seals, instead using magnetic couplings or submerged motors to eliminate points of failure caused by temperature differences.

6. Vapor Handling: These pumps are equipped to handle any vaporized gas that forms during the process, ensuring stable and efficient operation without cavitation.

Product Features

1. Pump and motor are completely imm ersed in medium, which can continuously cool the pump.
2. The pump is vertical structure, which makes it operate more steadily with long service life.      
 

Product Features

3.The motor is designed based on inverter technologies.
4. Self-balancing design is applied, which 5. makes radial force and axial force automatically balanced during operation of whole pump and extends service

The buyer of a cryogenic submerged centrifugal pump, especially of the immersed type, could vary depending on the application and industry. Here are a few potential buyers:

1. Industrial Gas Companies: Companies involved in the production, storage, and transportation of liquefied gases such as oxygen, nitrogen, argon, or LNG (liquefied natural gas) often require specialized cryogenic pumps for their operations.

2. LNG Terminal Operators: LNG terminals utilize cryogenic pumps for the transfer of liquefied natural gas between storage tanks and carriers, as well as within the terminal infrastructure.

3. Medical Institutions: Facilities dealing with medical gases, such as hospitals or research laboratories, might require cryogenic pumps for the handling and distribution of liquid oxygen or nitrogen.

4. Space Agencies: Organizations involved in space exploration may need cryogenic pumps for fueling rockets with liquid oxygen or liquid hydrogen.

5. Industrial Applications: Various industrial processes, such as semiconductor manufacturing, food processing, or metal fabrication, may require cryogenic pumps for specific cooling or handling purposes.

6. Energy Companies: Companies involved in the production and distribution of liquefied gases for energy purposes, such as natural gas liquefaction plants, could also be potential buyers.

7. Marine Industry: Shipbuilders or operators of vessels that require cryogenic fluids for cooling systems or fuel could also be interested in these pumps.

Each of these buyers would have specific requirements and specifications for the cryogenic pumps they need, so suppliers of such pumps often tailor their products accordingly.
