Milwaukee M18 18V Cordless Transfer Pump (Cat No. 2771-20)

This is a Milwaukee M18 cordless transfer pump, model number 2771-20. The unit features a rugged, impact-resistant black and red plastic housing with an integrated carry handle positioned on the side for portability. It is constructed to handle standard water transfer applications. Notable markings include the red and gold 'Milwaukee' and 'Transfer Pump' identification labels, which include a detailed warning and instruction sticker in English, French, and Spanish. The device incorporates brass fittings at the top for hose connections; a blue flexible hose is currently attached via a brass coupling. The item shows signs of heavy industrial or residential use, including surface abrasions on the black plastic casing, some accumulation of dirt and debris in the crevices, and slight peeling or wear on the edges of the primary identification label. It is designed to be powered by an 18V M18 RedLithium battery pack (not visible in the shot). The craftsmanship reflects professional-grade power tool standards, with reinforced screw-hole housings and a textured grip on the handle for better ergonomics during use.

I have conducted a visual examination of the Milwaukee M18 Cordless Transfer Pump (Model 2771-20). The unit exhibits definitive characteristics of an authentic Milwaukee tool, including the proprietary RedLithium branding, triple-language safety decals, and high-quality brass inlet/outlet fittings. The build quality and hardware positioning are consistent with professional-grade production standards. Condition Assessment: The item is in 'Good' to 'Fair' used condition. Significant surface abrasions and particulate accumulation in the housing vents indicate heavy field use. While the brass fittings appear structurally sound without cross-threading, the peripheral wear on the labels and the scuffing on the impact points suggest a life of industrial service rather than homeowner use. There is no visible evidence of thermal damage or internal sealant leakage. Market Analysis: This specific model is a high-demand item in the plumbing and HVAC sectors. New retail units typically command $229.00 for the 'tool-only' configuration. Secondary market data for used units in similar functional condition shows a consistent range from $110.00 to $150.00. The absence of a battery pack and charger in this assessment slightly suppresses the valuation. Limitations: This appraisal is based solely on digital imagery. A definitive valuation would require a load test to verify the 480 GPH flow rate and an inspection of the internal impeller for cavitation damage. I could not verify the integrity of the battery connection terminals or the pump's ability to prime without a physical test. Full authentication would require verifying the serial number against Milwaukee’s registry to confirm it is not a grey-market or counterfeit housing.
