DEF Pumps

DEF pumps are specialized fluid-transfer devices engineered to dispense Diesel Exhaust Fluid (DEF)—a urea-water solution required for Selective Catalytic Reduction (SCR) systems in modern diesel engines. These pumps utilize DEF-compatible components like stainless steel, polyethylene, or polypropylene housings, and EPDM or Viton seals to prevent crystallization and maintain fluid purity. Available in styles such as diaphragm (electric, air-operated), hose-mounted electric, hand pumps, and submersible units, they support safe, contamination-free dispensing from drums, totes, and bulk tanks.
