CS&P 50mm Complete Pump Skid — 75 HP Cryogenic Liquid Transfer

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

The listing does not provide flow rate, discharge head, or NPSH requirements for this skid. CS&P 50mm pumps typically deliver 150–300 GPM depending on head and service, but you'll need to ask the seller for the actual performance curve and minimum required NPSH for this unit. The 75 HP motor suggests this is configured for higher head or multiple-pump operation compared to standard single-stage centrifugal builds.

What should I inspect on a used pump before buying?

Check the impeller and volute for erosion or cavitation damage, verify the mechanical seal faces for scoring, and confirm the motor bearings turn smoothly without play or noise. On cryogenic skids, inspect the vacuum jacket integrity, all vacuum ports and relief valves, the condition of flexible cryogenic piping, and verify the 2-ICPV200 pressure control components are complete with calibration records if available. If the unit saw LOX service, confirm oxygen cleaning certification is current or budget for recleaning and revalidation.
