Product Description

High Performance And Various Type of Cryogenic Liquid Pump


Our cryogenic liquid pump is designed to efficiently transfer low - temperature liquids with high reliability. It features advanced technology and high - quality materials, ensuring stable operation in extreme cold conditions. Whether for industrial or scientific applications, this pump offers unrivaled performance.

Product Description

Cryogenic Submersible Pump

Cryogenic submersible pumps are specifically engineered to handle the transfer of cryogenic liquids, such as liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, and liquid hydrogen. These pumps are designed to be submerged directly in the cryogenic liquid storage tank or vessel.

The pump consists of a motor and an impeller. The motor is hermetically sealed to prevent the ingress of cold and potentially explosive cryogenic vapors. The impeller, usually made of special alloys with high strength and low thermal expansion coefficients, is connected to the motor shaft. When the motor is energized, the impeller rotates at high speed, generating the necessary pressure to force the cryogenic liquid out of the tank through the discharge line. The pump housing is also constructed with materials that can withstand the extremely low temperatures of cryogenic liquids without losing their mechanical properties.

Advantages of Our Cryogenic Submersible Pumps:
 

1. High Efficiency: Advanced impeller design enables cryogenic submersible pumps to achieve high flow rates with 10 - 20% less power consumption compared to traditional above - ground pumps, bringing long - term cost savings.

2. Low - Noise Operation: Being submerged in cryogenic liquid, these pumps generate minimal noise, which is beneficial in noise - restricted areas and reduces workplace ambient noise pollution.

3. Enhanced Safety: The submersible design and hermetically sealed motor minimize the risk of cryogenic liquid leakage and ignition sources, significantly improving the safety of cryogenic liquid handling systems.

4. Compact Installation: Cryogenic submersible pumps can be directly installed in the storage tank, requiring less space and simplifying the transfer system for easier maintenance and operation.

5. Good Adaptability to Low Temperatures: Carefully selected materials for pump components ensure the pump operates smoothly and reliably across a wide range of cryogenic temperatures from - 196°C to - 269°C.



 

Cryogenic Centrifugal Pump

Centrifugal pump is a pump where liquid moves and required head forms by means of centrifugal force raising as a result of impeller blades effect on fluid.

Cryogenic pumps are classified as single-staged with one impeller and multi-staged with several impellers however with the same working principle.

Cryogenic centrifugal pumps are used for large amounts of liquefied industrial gas (liquid oxygen, liquid argon, liquid nitrogen) pumping. It is also reasonable to use pumps of such a type for liquid pumping from one capacity to another.

Advantages of Our Cryogenic Centrifugal Pumps:

Cryogenic stainless steel bearing life 20,000 hours;
Reliable mechanical and labyrinth seals;
Frequency converter provides the necessary speed range of the pump;
Volutes and impellers are made of copper alloy to guarantee high performance pumps;
High cavitation resistance;




 

Cryogenic piston pump

Piston pumps are designated for conversion of motor mechanical energy into pumped fluid mechanical energy.
Pump fluid suction is caused by low pressure formation in a process chamber during a piston right motion and with closed discharge valve

Cryogenic piston pumps can be both of a single low-temperature section type and a multiple low-temperature section type.
Cryogenic piston pumps are used for buffer reservoir filling, cryogenic cylinder filling, as well as for industrial and medical bottle filling with gaseous products. It is reasonable to use pumps of such a type also in severe application (industrial application of LNG and CO2) where high pressure is a significant factor.

 

Advantages of Our Piston Pump:
Single or multiple cold end design to meet various flow rates, reduce the flow impulse;
Ex-proof electric devices as motors and control units to meet the LNG working conditions;
Specially seals ensure a long time of free maintenance to the cold end, up to 3500 hours;
Multiple cold end design to fulfill high flow service;
Vacuum jacketed cold end minimizes heat loss and lowers liquid's vaporization;
Interlocking system ensure protection from wrong operations;
24-hour persistent performing;
All electric components are configured as per anti-explosion requirements;
The piston seal is made of special material and the service life of the piston seal is over 4000 hours;
Low discharge pressure fluctuation;
Fast precooling ;
The simple pump head module design facilitates maintenance;
The pump has the design of new type gland packing and ultra-long service life;
Maintenance is convenient: it merely takes two hours to perform a routine maintenance;
