Product Details
4 GPM 3:1 Polypropylene Air Operated Low Pressure Diaphragm Pump with 1/4" NPT Inlet, 1/4" NPT Outlet by Lincoln®. Diaphragm pumps are 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 advantages over other pumps.
Notes
- The pump exhaust should be piped to an area for safe disposal of product being pumped in the event of a diaphragm failure.

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
