DLA Land and Maritime is seeking additional sources for NSN 3010-01-270-6525, currently approved to Dover Pumps & Process Solutions Segment (07524) for part E-4564B. The item has AMC 3 / AMSC C, meaning it is acquired directly from the actual manufacturer and requires engineering source approval by the design control activity to maintain quality because the approved source holds essential data rights or technical knowledge. Interested manufacturers may submit information directly to Contract Specialist Logan McLaughlin at Logan.McLaughlin@dla.mil. Companies wishing to become an Approved Source can apply through the DLA Land and Maritime Alternate Offer/Source Approval Request (SAR) Program, with the burden on the contractor to demonstrate equal or better quality than the OEM.
