The US Coast Guard requires 15 units of a specific centrifugal reverse osmosis boost pump assembly (NSN 4320-01-547-3986, P/N 70-0027) with a Viton mechanical seal for saltwater applications, and the part number must be marked on each pump. Offerors must quote the brand name part or an equivalent that meets the salient physical, functional, and performance characteristics, with the Coast Guard determining acceptability. Quotes must comply with strict military packaging standards (MIL-STD-2073-1E Method 10) using specified wooden or fiberboard boxes, with skid mounting required for boxes over 50 lbs; standard commercial packaging is unacceptable. Award will be a firm fixed-price contract on an all-or-none basis, lowest price technically acceptable, using simplified acquisition procedures. Offerors must be registered in SAM, have valid DUNS numbers, provide their TIN, and submit required representations including the HSAR inverted domestic corporation disclosure.
