Questions buyers ask
What service has it been in, and what were the running hours?
This unit is new and has never been removed from the original crate, so it has zero running hours and has not been in service. It was manufactured in 2021 and has been in storage since then.
What seals, materials and drive does it have?
The pump has a pressurized oil lubricated drive with integral oil pump and reservoir, and features what the manufacturer describes as a "state-of-the-art internal sealing design," but specific seal types and wetted materials are not detailed in the listing. The drive is powered by a 150 HP 460V 3-phase inverter duty motor rated Class 1, Div 2, Group A,B,C,D. For liquid hydrogen compatibility, wetted materials are typically austenitic stainless steels or special alloys; confirm the exact materials of construction and seal configuration with the seller.
What should I inspect on a used pump before buying?
This unit is new, but on used triplex cryogenic pumps generally inspect the plungers and packing for scoring or wear, verify the vacuum jacket integrity with a vacuum gauge reading, check the drive end for oil leaks and bearing noise, and examine all wetted parts for corrosion or embrittlement from previous cryogenic service. Confirm the suction and discharge flanges, relief valve settings, and motor insulation resistance, and request service records documenting what cryogen was pumped—cross-contamination history matters for hydrogen applications.
