Lincoln 1/2″ Polypropylene Diaphragm Pump 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.
Key source specifications include Air Inlet Threading: 1/4″; Pump inlet/outlet: 1/2″ / 1/2″; Maximum Inlet Pressure: 100 psi; Model 85626.
