Ebara Cryodynamics is proud to be recognized as the foremost producer of submersible pumps and expanders for the ever-growing liquefied gas industries. Recently exceeding 6,500 units installed aboard LNG Carriers and land based installations, Ebara is represented at the vast majority of LNG operations in liquefaction, marine transport and re-gasification applications.
Ebara’s Submerged Motor-Generators are designed to operate in non-conductive liquefied gases eliminating rotating seals and all associated concerns. Sharing a single shaft with the pump or turbine element, alignment and safety are assured as the unit is segregated from hazardous classified areas.
Ebara Cryogenic Pumps are applied in three distinct configurations:
- Serving aboard most of the world’s LNG Carriers as Cargo, Spray and Emergency Pumps are Model EC units stationary mounted at tank bottom with complete power feed and deck penetration assemblies by Ebara.
- Suction Vessel Mounted Pumps (Model ECC) are utilized as single stage transfer pumps or multi-stage for vaporizer feed and send-out service.
- Model ECR Retractable Units are designed for LNG storage tank installations via columns which contain the pump and provide a discharge. The pump weight opens a spring loaded suction valve as also supplied by Ebara. This allows a system for pump removal from a loaded tank with the column being safely innerted.
In addition to Cryogenic Pumps, Ebara Cryodynamics’ Expanders exemplify our drive for advancing LNG process technology and productivity. These machines directly produce approximately 5% increased plant output while generating substantial electricity as a peripheral benefit. These innovative machines, recently advanced for both Single-Phase (liquid) and Two-Phase (Gas/Liquid) applications, can also be provided with variable speed technology. Ebara’s Client-Partners have worked closely with us to optimize performance and reliability to reap the outstanding attractive results of this technology. Ebara Cryodynamics’ Expanders are becoming the specified standard in LNG production trains around the world.
