Air operated diaphragm pump
Lincoln
1/4" - 2" Air-Operated Pumps
Basic Design Features
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 advances over other pumps.
