Lincoln 85630 1/4 in. Diaphragm Pump

Lincoln 85630 Diaphragm Pump

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.
