Counterflow Drum Pumps (also called reverse flow drum pumps) are specialized manual pumps designed to minimize contamination and spills by allowing the pump and hose to drain back into the drum when not in use. This prevents dripping and cross-contamination, making them ideal for chemicals, lubricants, and food-grade liquids.
✔ Self-Draining Hose & Pump – Liquid flows back into the drum when not in use.
✔ Sealed Design – Reduces leaks and exposure to hazardous materials.
✔ Chemical Compatibility – Often made of polypropylene, stainless steel, or PTFE for harsh liquids.
✔ Manual Operation – Typically rotary-handle or lever-action.
✔ Versatile Use – Common in industrial, automotive, and food processing applications.
Tractor Supply – May carry basic models (check online or in-store).
