What the government is buying
The Navy is soliciting offers for pumps, rotary through NAVSUP Weapon Systems Support in Mechanicsburg, Pennsylvania. This is a supply acquisition for NSN 4320-class equipment, which covers mechanical equipment used across naval vessels and shore facilities. Rotary pumps move fluid through rotating mechanisms—gear pumps, vane pumps, screw pumps, or lobe pumps depending on the specific application—and are critical components in fuel transfer, lubrication systems, hydraulic power, and cooling systems aboard ships.
NAVSUP WSS is the Navy's primary inventory control point for weapon systems support, managing spare parts and provisioning for afloat and ashore operations. Procurements through this organization typically require compliance with military specifications and standards governing material, performance, and testing.

Who can bid
This solicitation is unrestricted—there is no small business set-aside, meaning businesses of any size may compete. However, small businesses in NAICS 333914 remain eligible and should evaluate whether they can meet any technical, quality, and past performance requirements the Navy establishes.
Key considerations for eligibility:
- Manufacturer or supply-source capability: You must demonstrate ability to produce or source rotary pumps meeting applicable military specifications. NAVSUP WSS typically requires traceability to approved designs.
- Quality systems: Expect requirements for ISO 9001 or AS9100 quality management, plus possibly Navy-specific source inspection or first article testing.
- Past performance: Relevant experience supplying to DLA, NAVSEA, or other Navy components strengthens competitiveness.
- SAM.gov registration: Current registration in the System for Award Management is mandatory, with no exceptions.
How to put together a competitive bid
Understand the technical requirements thoroughly. NAVSUP WSS solicitations for mechanical equipment typically reference specific military or commercial item descriptions. Review every cited specification—MIL-PRF, MIL-DTL, or performance specifications—for material, dimensional, and testing requirements. Deviations usually require advance approval.
Validate your supply chain early. If you do not manufacture rotary pumps directly, identify approved subcontractors or OEMs immediately. The Navy often restricts alternates to qualified sources. Obtain any required source approval or qualification before submitting.
Price strategically with total cost in mind. Unrestricted competitions against large manufacturers favor competitive pricing, but avoid unsustainable low bids. Factor in first article inspection, testing documentation, packaging for military shipment, and any special marking requirements.
Address delivery and packaging explicitly. NAVSUP WSS has strict packaging and marking standards (likely MIL-STD-2073 or equivalent). Noncompliant shipments face rejection. Confirm your capacity to meet required delivery schedules and any drop-ship instructions.
Prepare robust past performance references. Even in unrestricted competitions, relevant experience with defense supply chains differentiates bidders. Document on-time delivery rates, quality acceptance history, and any prior Navy or Marine Corps awards.
