Wilmar Corporation W54285 Rotary Barrel Pump Def

Product Description

The WILMAR CORPORATION W54285 is a hand-operated rotary barrel pump designed for transferring diesel exhaust fluid (DEF) and a range of other liquids from standard bung-fit drums and pails. The rotary lever action delivers approximately 7 gallons per 100 revolutions, making it practical for regular fluid transfers in fleet maintenance, agricultural, and industrial settings. The pump body is constructed of polypropylene with PTFE vanes, providing broad chemical resistance. A built-in one-way check valve helps prevent backflow and product contamination between uses. Licensed mechanics, fleet techs, and shop personnel typically deploy this pump for routine DEF handling and fluid management tasks.

The W54285 fits all 5-gallon to 55-gallon pails and drums equipped with a standard bung fitting, covering the most common drum sizes in commercial and industrial environments. Its chemical resistance profile extends to gasoline, diesel, machine oil, alcohol, and acidic fluids, making it a multi-purpose transfer tool beyond DEF alone. It is well suited for fleet shops, agriculture operations, construction sites, and any facility that handles bulk fluid storage in drum format.

Installation Notes

Installation requires inserting the pump inlet tube into the drum bung opening and securing it per the bung fitting threads. Ensure the drum is stable and on a level surface before pumping to prevent tipping. Flush the pump with a compatible neutral fluid between uses when switching between different fluid types to avoid cross-contamination. No special tools or trade licensing are required for standard installation, though proper chemical handling practices should be followed per applicable facility safety guidelines.
