2014 ACD Nikkiso TC-34-KA LNG, LIN, LA

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

This pump is rated for 51 GPM at 1175 feet of head with an NPSHR of 3.1 feet. It operates at 7200 RPM with a 6.00-inch impeller and delivers 236 PSIG discharge pressure at 20 PSIG suction pressure. The maximum allowable suction pressure is 50 PSIG.

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

The pump operated in LNG service. The listing states the unit is unused and manufactured in 2014, but does not specify accumulated running hours—ask the seller for service records or actual runtime if this is critical to your evaluation.

What seals, materials and drive does it have?

The case is bronze/stainless steel construction, and the unit is driven by a 14.7 HP motor at 7200 RPM. Specific seal materials and type are not listed—ask the seller for seal configuration and materials of construction for all wetted parts, as these are critical for your intended service.

What should I inspect on a used pump before buying?

On cryogenic submersible pumps, inspect the motor windings and insulation for any degradation from thermal cycling, check shaft runout and bearing condition, and verify the impeller for erosion or cavitation damage. Inspect all seals and O-rings for hardening or cracking, confirm the sump and discharge instrumentation are functional, and request pressure test records if available. Since this unit is listed as unused, verify storage conditions and preservation measures taken since 2014, as prolonged storage can affect seals and motor components even without runtime.
