ACD Complete Pump Skid — 15 GPM 75 HP Cryogenic Pump

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

This skid is rated for 15 GPM flow. The listing does not specify discharge head or required NPSH, which you'll need to request from the seller along with the pump curve. Cryogenic pumps typically require tight NPSH margins due to low fluid density and vapor pressure constraints, so knowing the actual suction conditions this pump was designed for is critical before sizing it to your application.

What should I inspect on a used pump before buying?

Since this unit is missing cold ends and sold as-is, verify the motor windings and bearing condition, check the skid frame and piping for cracks or corrosion, and confirm all mounting points and support structure are intact. On cryogenic pump skids generally, inspect vacuum jacket integrity if present, look for evidence of thermal cycling damage on welds and flanges, verify instrument ports and valves aren't frozen or corroded, and confirm the electrical panel components and wiring are serviceable. Request any available documentation on cold end specifications so you know what you're sourcing to complete the unit.
