Frequently asked questions

Find answers to common questions about our products and services

  • This pump is designed exclusively for DEF (Diesel Exhaust Fluid). Compatibility with other fluids is not specified for this product, so it should not be assumed suitable for other chemicals or lubricants without confirming with the manufacturer.

  • No — this is an air-operated diaphragm pump, meaning it runs on compressed air rather than electricity. This makes it well suited for environments where electrical power sources may be limited or where spark-free operation is a practical consideration.

  • DEF is a corrosive urea-based solution that degrades many common metals and polymers. Polypropylene is a DEF-compatible material, which is why this pump is constructed from it — ensuring the fluid path resists chemical breakdown during transfer.

  • Both the inlet and outlet ports on this pump are 3/4", so you will need 3/4" hoses and fittings on both the supply and discharge sides of your DEF transfer setup.

  • This pump delivers 14.8 GPM, so a 50-gallon DEF container would take roughly 3 to 4 minutes to fill, and a 100-gallon tank approximately 7 minutes, helping you plan your dispensing workflow efficiently.
