The Flux Pumps F425 liquid saver pump can efficiently pump out 99.98% of the contents of a 55-gallon drum, leaving less than 1% residual. The pump features a foot valve that can be closed with minimal effort before removing it from the container. This ensures that any backflow of fluid is captured, preventing it from being left in the barrel. As a result, this pump can help reduce expenses on costly media and minimize cleaning and disposal costs associated with handling hazardous chemicals.

Fluid examples:

  • Acids
  • Alkalis
  • Petroleum products
  • Flammables
  • Solvents
  • Fuels
  • High value liquids
