ACD 50mm Complete Pump Skid — 75 HP 460V LNG

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

The listing does not provide flow, head, or NPSH specifications for this unit. For a 50mm LNG pump, these parameters depend on impeller design and speed; you'll need to request the original pump curve or nameplate data from the seller to confirm rated performance. The 75 HP motor size suggests substantial flow capacity, but without the cold end assembly present, verification against OEM specifications is essential.

What seals, materials and drive does it have?

The unit has a 75 HP 460V motor, but seal type and wetted material specifications are not listed. The cold ends are missing, so the pump barrel, impeller, and mechanical seal assembly are not included with this skid. You should confirm with the seller what remains of the seal housing and whether the vapor barrier system or any seal support components are present on the baseplate.

What should I inspect on a used pump before buying?

Since the cold ends are missing on this unit, verify what components are actually present beyond the motor and skid framework—check for the pump barrel mounting flange, instrumentation ports, relief valves, and any auxiliary systems. On cryogenic pump skids generally, inspect motor bearings for moisture intrusion, check all piping and valve bodies for impact damage or corrosion, and verify that support steelwork hasn't been modified in ways that affect alignment. Request any available maintenance records and confirm the motor can be megger-tested before shipment.
