Lincoln 1/2" Aluminum Diaphragm Pump - 85633

The Lincoln Diaphragm Pump is driven by compressed air. The directional air distribution valve and pilot valve—the “air end”—are located in the center section of the pump. Liquid moves through two manifolds and outer chambers of the pump—the “wet end”. Generally, check valves are located at the top and bottom of each outer chamber or on a common manifold. The two outer chambers are connected by suction and discharge manifolds. Lincoln’s double diaphragm self-priming design offers many advances over other pumps.

Product Features

• 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
