Cryodynamics® offers complete package solutions for all of your marine pump requirements. With nearly 4,000 marine units installed throughout the world, Cryodynamics has earned a solid reputation for providing machines designed for dependability and endurance.
Similar in construction to the ECC type, these machines are usually located within the refrigerated cargo tank of a marine gas carrier to transfer such fluids as LNG, LPG, and ethylene. These units are available for all applications of liquefied gas carriers and are used for main cargo unloading, stripping, spray, fuel, and emergency (retractable) service. Depending on your unique requirements, flow capacities range from 5 to 3000 m3/h and with heads up to 200 meters. Additionally, electric power feed cables and deck penetration assemblies to accompany your equipment are available and meet all requirements of major ship classification societies. Special designs with built-in internal filtration are available to handle cargo that is likely to suffer particulate contamination such as LPG. Whatever your situation, Cryodynamics can create a custom package to meet your specific needs.
Using the extremely low NPSHR of Cryodynamics spray pumps, cargo tanks can be off-loaded to near zero liquid levels, increasing the amount of the delivered cargo, reducing the cost of transportation, and the amount of heel product in the tanks during return voyages.
In the highly unlikely event that both cargo pumps were to fail on board, an emergency pump can be used to empty the cargo pump storage tank so that the main cargo pumps can be removed and serviced.
To date, thousands of Cryodynamics cargo pumps have been delivered and Cryodynamics is not aware of any of our emergency pumps being used in service, a testament to the reliability of the design.
To meet the growing demand of LNG fueled vessels, Cryodynamics has developed low-flow, high-head LNG fuel pumps. These submerged pumps are designed to meet the rigorous conditions of marine fueling applications. The rugged construction of these pumps allows years of uninterrupted service, even while operating with fuels containing some amount of contamination.
Cryodynamics also provides dual duty pumps. These machines offer two points of available operation, one being the spray duty and the second being the fuel duty, adding more versatility and scope to your cryogenic equipment.
