Dual Pump Skid — 51 GPM Cryogenic Pump Skid

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

This skid is rated for 51 GPM flow rate. Head capability and NPSH requirements are not specified in the listing and should be requested from the seller, as these parameters are critical for system integration and depend on the specific pump model and impeller configuration.

What seals, materials and drive does it have?

Seal type, wetted materials, and motor specifications are not detailed in the listing. Cryogenic pump skids typically use mechanical seals rated for low temperatures with austenitic stainless components in the flow path, but you should confirm the specific seal design, materials of construction, and drive motor voltage and horsepower with the seller.

What should I inspect on a used pump before buying?

Check mechanical seal condition for leakage or damage, inspect impeller and volute for erosion or cavitation pitting, verify shaft runout and bearing play, and examine valve packing and instrument ports. On dual skids specifically, confirm both pumps rotate freely, inspect all cryogenic piping joints and flex hoses for cracking, verify pressure gauge and relief valve certification dates, and test the control panel if installed.
