Cryogenic pump selection, LNG & air-separation applications, CO₂ skids and delivery — answered by SANJING engineers.
What cryogenic pump types does SANJING manufacture?
SANJING engineers submerged pumps, centrifugal pumps, reciprocating (piston) pumps, vaporizers, cryogenic storage tanks and skid-mounted pump systems for LOX, LIN, LAr and LNG service.
Which cryogenic pump is best for LNG refueling stations?
LNG and L-CNG filling stations typically use cryogenic reciprocating (high-pressure) pumps or submerged pumps. Submerged pumps reduce boil-off, while reciprocating pumps deliver the high pressure needed for vehicle filling.
Can your cryogenic pumps be used in air separation plants?
Yes. Our centrifugal and reciprocating pumps are widely applied in air separation units (ASU) for filling liquid oxygen, liquid nitrogen and liquid argon, with stable pressure and low maintenance.
Do you supply CO₂ and LCO₂ pump skid systems?
Yes. SANJING provides LCO₂ pump skid systems and high-pressure CO₂ cylinder-filling pump skids for carbon capture, utilization and storage (CCUS) projects.
What is your lead time and export experience?
With 30+ years of manufacturing and exports to 80+ countries, standard pumps ship in weeks; engineered skid systems are quoted per project scope.
