Offload Cryogenic Pump Connection / LNG / Cryo

What flow and head is this rated for, and at what NPSH?

The listing does not provide flow rate, head rating, or NPSH specifications for this connection assembly. Contact the seller for the specific performance curves and inlet requirements. Cryogenic pump offload connections are typically matched to the pump they serve, with flow capacity ranging from 50 to 500+ GPM depending on the pump model and application.

What service has it been in, and what were the running hours?

This unit is listed as new condition from 2014, meaning it has not been in service. Ask the seller whether this is new-old-stock that was stored since manufacture or if it was briefly installed but not commissioned. On used cryogenic connections, verify what product it handled, as contamination from incompatible fluids or moisture ingress during storage can damage seals and seats.

What should I inspect on a used pump before buying?

This is a connection assembly, not a complete pump, so focus on seal condition, flange face integrity, and freedom from corrosion or moisture contamination. On any cryogenic equipment stored since 2014, inspect all elastomers and soft seals for age-related hardening or cracking, verify that protective caps were in place, and check internal passages with a borescope for oxidation. Request documentation showing proper storage in a climate-controlled environment, as thermal cycling and humidity will degrade seals even on unused equipment.
