Why This Product
Direct Drum Transfer — No Decanting Required
Drum pump design transfers liquid directly from 55-gallon drums and totes without tilting, pouring, or manual handling. The pump tube submerges in the drum and pulls from the bottom — maximizing product recovery and minimizing manual handling.
Multiple Fluid Tube Options
Polypropylene, stainless steel, and PVDF pump tube options cover compatibility from water and mild chemicals to concentrated acids, solvents, and aggressive process fluids. Select the tube material matched to your fluid.
Portable Operation
Portable pump and tube assembly transfers between drums without tools — insert the tube, connect the outlet hose, and start pumping. One pump serves multiple containers throughout the facility.
Stainless Steel Construction Option
Stainless steel tube and wetted parts for pharmaceutical, food-grade, and high-purity chemical transfer where contamination from plastic or non-stainless metals is unacceptable.
Electric Drive — Consistent Flow Rate
Electric motor provides consistent flow rate regardless of operator fatigue — unlike hand pumps where output varies with operator effort. Suitable for high-volume drum dispensing operations.
ATEX-Compatible Options
Available in configurations for use with flammable liquids where ignition risk from static discharge or electrical arcing must be controlled. Consult AMT for explosion-proof and ATEX-rated configurations.
