Air & Liquid Systems Corporation

Air & Liquid Systems Corporation, operating through its Buffalo Pumps division based in North Tonawanda, New York, is a manufacturer of industrial pumps and related equipment that has established itself as a significant supplier to the Department of Defense and federal government agencies. The company specializes in the design and manufacture of centrifugal pumps, fire pumps, specialty pumps, and associated components including seals, gaskets, shafts, impellers, and other mechanical parts used in maritime and industrial applications. Since its registration in SAM.gov in July 2001, Buffalo Pumps has maintained continuous federal contracting relationships, serving as both a prime contractor on direct awards and as a subcontractor to major defense shipbuilders, positioning itself as a qualified vendor for critical equipment and spare parts supporting naval and military logistics operations.

Buffalo Pumps has demonstrated broad capability in providing specialized industrial components through multiple categories of federal contract awards spanning from 2021 through 2025. The company has received prime contract awards from the Naval Supply Systems Command (NAVSUP) valued in the hundreds of thousands of dollars for complete pump units and assemblies, including a $588,729 contract for a pump unit and multiple awards exceeding $100,000 each for centrifugal pump units, pump end assemblies (SEPA), and specialized pumps such as stern tube pumps. The company has also fulfilled numerous Military Sealift Command contracts for ship-specific components supporting vessels including the USNS Richard E. Byrd, USNS Robert Peary, USNS Medgar Evers, and USNS Washington Chambers, with awards ranging from $20,000 to $83,000 for fire pump parts, shafts, and OEM pump components. Beyond these larger prime contracts, Buffalo Pumps holds an extensive portfolio of delivery orders from the Defense Logistics Agency Land and Maritime, which has been the most frequent awarding agency, issuing over 100 individual delivery orders for items including seals in various configurations (plain, plain encased, and special), gaskets, shaft sleeves, impellers, wearing rings, couplings, retainers, and other pump-related components. The company has also received awards from the Naval Sea Systems Command for components such as flanged nipples and screws. All of these awards were issued on a firm fixed-price basis without small business set-asides, reflecting open market competitive procurements. Additionally, Buffalo Pumps serves as a subcontractor to major shipbuilding firms including Huntington Ingalls Incorporated and National Steel and Shipbuilding Company, providing work on destroyer classes (DDG-141, DDG-142, DDG-133) and performing capital expenditure and material change work related to pump systems.

Buffalo Pumps currently holds six active indefinite delivery contracts with the Defense Logistics Agency Land and Maritime, each with a ceiling value of $250,000 and all awarded as single-award vehicles with total small business set-asides. These IDVs, established between December 2021 and January 2022 with completion dates ranging through December 2022, cover the procurement of specialized industrial components on an as-needed basis to support DLA's global logistics missions. The first IDV, with NSN 4610085200, is designated for seal special components and has generated four delivery orders totaling $14,110 for items delivered to North Tonawanda. A second IDV under NSN 4610084744 addresses gasket procurement and has resulted in eight delivery orders totaling $2,560 for various gasket configurations delivered between June 2022 and February 2023. A third vehicle, NSN 4610084326, covers plain encased seals and has supported multiple delivery orders ranging from $48 to $192 for items delivered through February 2023.
