  • Strong vacuum/Self-priming to 25 feet
  • Handles air and fluid without damaging cavitation
  • Low Shear
  • Ability to pump thick, viscous fluids
  • Steady, measured flow at constant pressure
  • Can run dry
  • Handles abrasives well
  • ATEX Zone 2 Category 3 Rating
  • Rapid Delivery
  • Only a 3 feet NPSHR usually
