Transfer compatible liquids quickly and efficiently with this manual rotary 55 gallon drum pump. Designed for standard 15 to 55 gallon drums and barrels, this high-flow hand pump helps move liquids from large containers into buckets, tanks, jugs, sprayers, and smaller storage containers with less lifting, tilting, and spilling. The manual rotary mechanism delivers up to 10 gallons per minute, making it a practical solution for faster fluid dispensing in fleet maintenance shops, agricultural operations, warehouses, janitorial supply rooms, workshops, garages, and industrial maintenance environments. This drum pump includes a 2-inch drum bung adapter with locking screw for secure installation on many standard drums with 2-inch drum openings. The locking screw helps stabilize the pump tube during operation for improved control and easier fluid transfer. Designed for compatible low-viscosity fluids, this pump is suitable for detergents, cleaning solutions, water-based cleaners, diesel, DEF, compatible coolants, and many common shop or industrial maintenance fluids. The corrosion-resistant construction helps improve durability during repeated use in demanding work environments. No electricity, batteries, or air compressor are required. Simply install the pump onto the drum, rotate the handle, and dispense fluid with smooth, controlled flow wherever drum storage and transfer are needed. For compatible low-viscosity liquids only. Always confirm chemical compatibility before use.
