Lincoln's double diaphragm self-priming design offers many advances over other pumps.

  • Pump abrasive and sheer-sensitive materials - Low interval velocities move abrasives easily with no damage. Gentle pumping action does not sheer fragile materials.
  • Pumps viscous materials - Even heavy or solids-laden materials can be pumped.
  • Environmentally friendly - No motors, seals or packing to leak.
  • Self-priming - Able to dry prime under most suction lift or flooded suction conditions.
  • Variable flow - Regulate the inlet air supply to adjust flow.
  • Runs dry without damage
  • Deadheads against closed discharge - Excessive back pressure stops operation without damage until discharge opens. Eliminates bypass systems or relief valves.
  • Explosion-proof - Eliminates sparking concerns of other electrical or rotating pumps.
