This is a Sole Source/Brand Name Justification form from NAVSUP Fleet Logistics Centers documenting a procurement for service and overhaul of two Denison Legacy Steering Hydraulic Power Unit (HPU) Main Hydraulic Back-Up Pumps, Model PVP61H, for a U.S. Navy vessel. The form identifies Denison Hydraulics as the manufacturer and establishes a brand name requirement restriction on this procurement.

The justification cites multiple factors supporting the sole source determination: proprietary data and technical specifications unique to the Denison Legacy 61 Series variable volume hydraulic pumps; the U.S. Navy Technical Manual's explicit identification of Denison Legacy Pumps and Rocky Mountain Hydrostatics (RMH) as the authorized manufacturers possessing specialized engineering data, tooling, and testing procedures required to restore pumps to military-certified condition under specifications MIL-P-17869A and MIL-S-901C Grade A; the requirement for direct replacement parts matching exact physical dimensions, connection interfaces, and performance characteristics of the original RMH-manufactured pumps; and the restriction to sources authorized to perform repairs on the Denison Legacy 61 Series product. The procurement is designated as a minimum requirements request for the government. The form was signed on 02/14/2025 with Activity SRF-JRMC identified as the procuring entity.
